They upgraded the sound quality and installed new items in my Hallett 270 in my driveway! Worth the wait and highly recommended.

Horrible people to deal with. Not neighborly and doesn't care about the general public and people just trying to do their job. They may put on a false persona to their customers idk but if you're not a customer and just passing by they're a complete @ss. read more

Taken many vehicle from boats, RV's and vehicle there. Always great work, very clean and sounds amazing.

Marks Audio- video recently installed a Tv, replacement of indoor and outdoor speakers on my travel trailer. His craftsmanship was outstanding and his customer service on the type of products I should have was outstanding. I dropped my trailer off on a Thursday and got it back the following Thursday . They clearly outlined the amount of work that was needed, the time that it would take to accomplish the work and as well a very very good price on the overall project. If you are looking to upgrade a television or replace those standard speakers in your Rv or trailer , I highly recommend Marks Audio-Video for your project. read more

In the age of quick fixes and sloppy work it's nice to find a shop that puts quality first. Mark's Audio-Video is located in an unassuming business center, but that doesn't stop people from searching them out -- they know good work when they see it! We heard about Mark's from our RV repair shop. They refer all of their AV work to Mark's, and for good reason. These guys take their time to listen to what the customer wants and then comes through with flying colors. We wanted to have a portable satellite radio and additional speakers installed in our RV, and we couldn't be more pleased with the outcome. They even found upholstery material that matched our dashboard! Thanks so much for working with us to make our RV more functional! You guys are the best!! read more

I recently had my Level III stereo system replaced and upgraded in my Hallett 240 boat. Mark's Audio installed the original system which lasted 19 years, and the new JL system is quite amazing. Justin and his crew were very professional, and their experience, quality and workmanship has gone beyond our expectations. If you have a boat that needs some tunes, Mark's Audio is the place for you. -Tony Fortunato read more

My husband and I bought a motor home in December 2015 that has 3 TVs. Only the one in the living/kitchen area was connected to the DIRECTV satellite receiver! We weren't happy with the RV dealer so we needed to find someone to connect all the TVs. We were referred to Mark's Audio-Video and met Justin and his dad, Mark who did a great workaround so that we can watch TV outside and in our bedroom with just a push of a button! A year later, I called Mark's again to set up our home entertainment. He hung our big screen, connected it to DIRECTV and our blue ray. He also installed a SONOS sound bar and wireless rear speakers. Mark and his assistant, Andrew did a fabulous job. They were courteous, they provided a great finished project that we have enjoyed immensely! They cleaned up after themselves and left us smiling! You can be sure you'll be happy if Mark's A-V is called to handle your audio video needs whether it's your motor home or your home. They even provide their service for cars and boats! I recently called him in again to move the TV in my craft room from one wall to another. He pulled wires and accessed electricity, hung the TV and connected it to my VCR (yes, I still have tapes that I want to watch on occasion ). AND NO WIRES ARE SEEN! Call Mark's for all your A-V needs! read more

We recently bought a house and used Marks Audio-Video to install all TV's/Surround Sound/DirecTV in our house. We can't say enough about how ecstatic we are with how everything turned out. Marks Audio-Video is not a flat screen installation service. Instead, they are your one-stop for your entire home entertainment system. Mark came out and told us what TVs would be good for each room we wanted TVs in-and each TV he picked for us is absolutely perfect-amazing picture and the perfect sizes. He also helped us decide which surround sound system would work best in our house within the budget we wanted to stay in. Mark also helped us with our DirecTV set up-and hooked up all our Netflix/Hulu/Pandora/Etc so everything worked perfect from the very first time we used it. Marks customer service is so awesome if you have any questions before/during/after installation. All of the work is flawless. You can't see a single wire or box-or any other equipment-it looks so clean-even the work behind the TV's is also pristine-and you can't even see it! I would highly recommend Mark and his team. The work, products and customer service is incredible and you wont be disappointed. read more

First of all I have to talk about Robert (owner). Not only is he just the most helpful person I've ever dealt with, but he is the most knowledge person I have talked to when it comes to just anything that has to do with Audio/Video equipment. I was looking into installing/upgrading speakers in my 2000 Honda Accord but I didn't want to get ripped off or put some no name brand speaker like all these cheap Asian owned places in the SGV area. I did some asking around from my fellow car lovers and Mark's Audio Video was highly recommended by everyone I asked. I can't ignore highly trusted credible sources, so I took a chance and went there. Robert helped me with find the correct speakers, at a reasonable price. Found some nice Alpines for my rear speakers with great bass. I didn't want to take up trunk space with a separate bass and box. Once I approved the speakers, he ordered them for me. Once he received them, I brought my car back and he had them installed within the hour. I was very pleased with the quality of the sound and the decent amount of bass with just rear speakers. I loved that he didn't try to upsell me on getting a bunch of things I didn't need or want and that he really listened to what I wanted. It wasn't about making as much money off me as he could. Robert addressed what my needs were and met them. Can't ask for better customer service than that. He also helped me with installing audio output so that I can hook up my iphone to my sound system so that I didn't have to rely on using my outdated CD player anymore. Who plays CD's anymore nowadays? After more than a year, speakers are still working like they are brand spanking new. I will definitely go back to Mark's Audio Video when I buy a new car in the future and upgrade the speakers. He also can install any aftermarket head units/monitor/GPS, the works. If you are interested in home entertainment installations, you can go to them also! If you want to go somewhere that is easy to deal with, no bull, no "care sales" type aggressive ploys, clean and professional work, you have to go to Mark's Audio Video. read more

I was in need of installing a backup camera on my vehicle since I have this huge bumper blindspot. After doing much research about where to go (Al & Eds, The Carshop, Audio Crafters, Six AutoSound), I decided finally on Mark's after getting a friend referral and meeting Robert, the owner of the car division. Not exactly sure why there have been no yelp reviews, but I must say, this place is probably one of the best well known kept secrets in the SGV area. My guess is because most of the existing patrons are not yelp / technology people (mid 50s?) and in addition to cars, many of them have work done to a theirs boats, which I can't speak to because I only have a car (my income bracket). I decided on this place in the mind because the price, although not the cheapest, offered the best combination of quality (if anything is wrong, I can bring it back anytime) and value (competitive pricing). I think if you are like me and purchase cars from CarMax, and don't want to haggle all day and don't want to risk a poorly done job, this place is for you. I once tried to have a GPS system installed in those east LA area vendors and not only did it only work some of the time, it almost caused a car fire, because yes, if wires are not properly organized, can cause very serious problems. Look for Robert, you will enjoy talking to him. read more

We are so happy with our new Fusion radio in our Hallett 255. Justin is fantastic! He took the time to explain every detail and also worked with us to pick the perfect system for our boat. We had concerns about getting remotes that would replace the old remotes since they were a different shape. He sent us pictures and made sure we were happy with the look before installing. They came out perfect. He was able to make them fit so you would never know they used to be a different shape. Justin also spent a lot of time going over how to use the new radio and remotes. I would highly recommend using Mark's Audio-Video! read more

I have been looking for someone to update the electronics in my 2008 Winnebago Voyage. Tried several "RV shops" and everyone was to expensive or couldn't understand what I wanted. A couple of our neighbors bought new RV's, in conversation with them they explained they bought the basic new coach then had everything added locally, I also checked with my local RV repair shop. All 3 recommended Mark's Audio-Video. So off I go to Mark's with my wish list in hand thinking I would be lucky to get half done. After several visits and conversations with Mark (the owner of 40 years) and his son Justin I have my list complete, new Samsung 39" LED up front, new Samsung Blu-Ray Surround, new HD satellite receiver, 280 watts of solar on the roof (was originally 160 watts but Mark found a deal and passed the savings to me) they even re-mounted my rear TV on a pivot so I could access extra storage. All for far less than I had imagined. Even the wife thought is was a great deal and much cheaper than buying a new RV! I had a lot of confidence in this shop when I dropped off my RV and they DID NOT let me down, the progress reports and pictures every couple of days via text, the open shop where you are welcomed on the shop floor, the always positive attitude. If you work on my stuff I am always there, like it or not. I was always welcomed with open arms, always walked through my RV to check progress and make sure everything was to my liking. After owning my RV for 6 years this was the best experience I have had. I would highly recommend Mark's Audio-Video for ANY home audio work and any electronic upgrades/repairs to any vehicle, RV or boat. Absolutely worth every penny invested. Thank you Mark, yea Justin too ! You guys are awesome. read more

The home theater surround sound receiver went out in my motorhome. My mobile RV tech recommended Mark. Marks knows RV's very well, as he owns one. He worked with my sometimes difficult extended warranty company to get the receiver replaced. He did an outstanding job and took almost an hour demonstrating the use of my new receiver with me. I also like the fact that he had room inside his building to keep my RV secure overnight. Mark was a delight to deal with. He also took the time to help diagnose a satellite issue that I had. He is now my go-to guy for anything audio/video related. read more

I purchased a motor home in December 2015. The first thing I had to add was a satellite system. So I went over to Benlo in Irwindale and he referred me to Mark Audio. So I drove around the corner and spoke to Justin and we struck a deal. Everything was done in one day and my family loves the set up. read more

My experience with Marks Audio couldn't have been better! Unlike the two other negative commentaries, I found Marks to be very professional, provide a very clean install, have a spotless shop, and take the time to brief the customer on the use of their new equipment. Justin provided a personable & knowledgeable level of customer service. If ever I would have an issue with Marks Audio - I am fully confident they would work diligently to make it right! Give them your biz - you won't have any regrets! read more

Perfect find for my stereo/ TV situation on my recent motorhome purchase! I met both Mark and Justin who work well as a father/ son team. Justin gets the praise for this first phase of having an upgraded stereo installed along with a current status on my TVs that already were in the coach. As they are RV 'ers themselves, they guide you thru the process and help you make a decision that meets your budget. Justin was extra detailed on teaching and showing what I had/ what was installed/ and what the next options look like. My trust level for Mark's Audio-Video is important/ crucial and now very strong for future RV upgrades as well as our personal vehicles. Now its time for summer getaways! read more

Having just finished building our custom home I feel compelled to share that you need to speak with Mark's Audio-Video. They can help whether you are looking to make small upgrades or are in the process of new construction or a remodel. Your electrician might think he can handle the low voltage but don't be fooled.You will be very disappointed and have a brand new home that is significantly outdated. It is much cleaner and more cost effective to pre-wire and plan the home infrastructure. This is a must have for an updated home and will become a standard you will want to have. For us that included a central media center, built in televisions, outdoor speakers, surveillance cameras, smart thermostat, smart lighting, and my favorite - the Lutron collection of blinds and shades. Mark's Audio Video does it all, they are beautiful and discrete and used everyday flawlessly. Mark and his team are experienced in designing, installing and making it all easy to work. They have sourced and are familiar with the quality products that right for the specific application. I feel that the entire audio, video, blind and lights are the most used and best finishing dollars we spent. A big thank you to Mark's Audio and Video. read more

Mark's Audio-Video is a first-rate shop. Mark and his team put together the whole sound system and network system for my home and they did a phenomenal job! Very high quality workmanship and their service is terrific. They are like Nordstrom's. Their price is reasonable and their quality is excellent. Mark has a knack for listening to his clients' needs and providing what they need in a very practical and effective way. I highly recommend them. read more

I had satellite issues with my RV and needed to get it fixed within two days. Justin diagnosed the issue, told me my options and my RV was up and running within time and for a lot less than I was expecting! read more

Do not do business with this place, you will have technical problems!!! I had a device installed in my car. They reinstalled it three times. Every time I was in there a customer was in there with a problem as well. I do not know how they stay in business. read more

This is not a flat screen installation service. They design and install fabulous home theater systems! We are so pleased with their service! They arranged for the new cabinet and integrated some of our existing equipment in the new design. Now all the equipment works with just one remote and we have a sleek, magnificent home theater with great sound and and a flat screen with the most beautiful color ever! Our installation was in September and everything works great! And if you're wondering, yes, the wires in the equipment racks were the neatest ever. Mark asked for our wish list when we started the project and he met them all! read more

Mark's Audio-Video has been doing work for my family since 1997. Mark and his team have been nothing but good to us. He has done everything for me including my motorhome, boat, sand car, and our cars. Mark and his home theater team just recently did an entire a/v system in my house that has been nothing but excellence. They added 20+ in ceiling speakers throughout my home, 5 TV's and programmed 2 Universal remotes. Mark and his team were very professional and made sure they still kept the house clean (possibly made it even cleaner). He did a full demonstration for us to make sure we knew how everything works and showed sincerity snd passion in his work and that is why I would recommend Mark and his team to anyone that I know for a/v work! read more

I wanted my RV analog TV replaced with a flat screen but wasn't sure were to go, I knew it was going to be a big job so I was referred to Marks Audio Video. After reading all the positive testimonials I knew this was the right choice for me. I met with Justin he told me what they were going to do, so he and his team went to work and the end result was better then I could have imagined, it looks better then factory. Mark, Justin and all the talented people at the shop you are true professionals and the customer service is simply the best. read more

I went here for quality service and quality workmanship. I got great quality service with no doubt at all. I was referred by many "auto" people to come here because this was the best. I knew it would be pricey and I was good with that because I knew I would not only be getting quality service and quality workmanship. I didn't even research any other places. My gut told me I would have zero issues. So, I got my vehicle done here. Paid for it and it was pricey but again, from the outside my vehicle looked sweet. So, about a year later or so, I decided to do a full frame off restoration to my vehicle. Obviously, I had to take my vehicle apart to start the project. What I was found was astounding. Nothing was done clean whatsoever as far as wiring etc etc etc. It was a complete mess. Wiring was crammed into places behind the dash, wiring was exposed to possible rubbing without the right protection, and there were many more issues. It was pretty ugly. Another example is that the wiring on the floorboard was installed underneath the Dyanamat. There were few zip ties and not a clean install by my opinion and by many many hot rodders and auto guys which came by to see it. They were absolutley shocked that Mark's Audio did this work. They did not believe me. They were actually dumbfounded. Again, the system worked excellent and the customer service was great, but the quality workmanship behind the dash and underneath the floorboard was absolutely appauling not only to me but the "auto" crowd that has stopped by to see it. It was a complete ugly mess. In my belief, if one is paying for this expensive type of service, quality workmanship should be a given inside and out. I will definitely not be going here again and I will be doing my own wiring now during the process of my frame off restoration and take my loss as part of a life experience. I do have to say very strongly that Robert is very nice and professional. read more
