I wanted to move the subwoofer/amp unit from my old car to the new one. And I came to Yelp with trepidation, looking for a trustworthy store to handle the removal from the old and installation in the new. My concern is that those car audio installation places are a gamble. Will your installer be a kid with little or no experience? Would someone do a hack job cosmetically? Or worse yet create the preconditions for a short circuit in my electrical system? Looking for a local operation, I came on 12 Volt Technologies. What's this? My first reaction was "Sure. I really want a nomadic installer working on my new car!" But my preconception of a fly-by-night operation dissolved pretty quickly when I started to read the reviews here. Glowing comments and 5-star reviews. The word "confidence" came into my mind more boldly as I read down the first set of reviews and then pressed on for more. The story everyone was telling was that they came to David looking for a solution to a specific set of requirements. And that he listened and made those things happen. David arrived ten minutes before our first appointment. I showed him the subwoofer/amp module and he told me that the car dealer who removed the unit from my old car didn't unplug the connector from the car stereo; they merely snipped the wire in a convenient location. Sure, I got the hardware back but David couldn't install the unit without either ordering the connector cable or fabricating his own. I apologized but he was not the least bit put out. He told me he'd check with the distributor and get back to me as soon as he knew which solution he'd adopt. And no charge for the visit-- which was supposed to have been a longer than typical appointment. A few days later he texted me to announce that the distributor had shipped the cable and he'd be back to me as soon as he had the tracking number. A couple days ago David came by with the connector cable and mounting parts. Again he arrived ten minutes early. Again a warm smile. He got to work and I am now enjoying subtle low bass augmenting the standard factory stereo system. I can't imagine that I might have driven my car up to a garage door in an industrial area and hoped for the best. Based on my experience with David's 12 Volt Technologies, I want to use his services in the future as I further enhance my sound system. I consider myself lucky that I live in his service area. And I will be recommending him to friends and family. read more

Twelve Volt Technologies - Install in progress. - Car Stereo Installation Near Me

The kid that runs this business is on point. Every meet someone and they just have that hustle like you know its not about the money they just love to do what they do? Thats what you get with David . First he was on time, like clockwork, was there when he said he'd be there. Second he told me it would take 45 minutes to install and he was done 46 minutes later. He did a fantastic job, it was quick, it was easy, it was affordable and then he sat and explained how everything works right after. For the price, you cant beat it, he comes right to your house and does his things, talk about convenience. If you need audio work on your car this kid will absolutely earn your business. read more

David installed an upgraded stereo in my car. He showed up early and worked for over 7 hours to get everything installed and dialed in. For the amount of work he did and the hours he worked his price was very fair. He gave me 3 different quotes. He also offered a couple of bundled options to save me some money. I would highly recommend him for any project you have. read more

David is awesome. Always professional, excellent communicator. Not only does he do meticulous work, he also provides multiple price quotes and different install options. I will use him for all of my car audio needs. Can't say enough about this guy. Keep up the great work. read more

I had David1 and David2 install a vhf/uhf ham radio in my 2021 toyita tacoma. I supplied most of the materials due to the non standard installation (transceiver behind rear seat, speaker, microphone, remote head unit, antenna). They did a fantastic job. It looks like a factory installation. They used seat covers to protect the interior during the installation. All cables were run in existing wire runs. The under the hood wiring isn't even noticeable. Three hours and they were done. If you want any after market electronics added to your ride call them. read more

I've had David out three times now for a range of projects on my 2006 Tacoma I'm rebuilding / upgrading: Car stereo followed by a amplifier/subwoofer, rear video camera, remote door lock/alarm, off road lights and pre-wire for an electric radiator fan. All were well done on time at a fair price. He's careful to cover up my seats so there is no damage. Been very happy. He tuned the amplifier / sub-woofer and it sounds great. Highly recommend. read more

David was prompt with his responses and answers to my questions. Did all the work requested and everything works perfect!

David goes above and beyond! He installed my car alarm system and my backup camera system in my conversion van. Very reasonable prices and he is so professional and sooo nice. He did a totally awesome job. I highly recommend him! He's flexible and his online system for booking an appointment is slick. He requires a $60 deposit up front but that goes towards the service when you pay. I was nervous at first to use the online booking system to fork over money without even meeting him first but don't worry..... he's completely legitimate! AND he comes to YOU. read more

For a mobile install business to have this many 5star reviews,you know they are doing something right. Dave recently did a great install for a blue tooth stereo and subwoofer on my truck in great order. From the get go he communicated great, let me know what was going on thru each step heading up to the appointment itself (showed up on time, crazy I know), and even fixed an electrical demon that I had with a PA system. All in all, Dave and 12Volt Tech are a great choice for your mobile electronics need. Great Service, fair price, quality work. read more

Dave is the best. Friendly, on-time, professional AF digitally and in-person, takes care in what he's doing and installed everything super clean without any mess or any issues - right in my driveway. I installed a Carplay interface in my 2017 Audi A3 and it works beautifully. He had to improvise a bit to run a new USB port thru my glove compartment and he did it quickly and it's super clean. Beautiful work Dave thanks a ton! I consulted with nearly 10 other local shops and Dave was the best solution all-around - cost, mobile installation, professionalism, convenience, responsiveness, customer service, and his knowledge. Definitely recommend. Hit him up! Thx again Dave awesome work! read more

David's a true professional and I highly recommend him to anyone. His honest and detailed communication and advice helped me figure out the best solution for my needs and I appreciate that level of customer service without a pushy sales pitch or vague double talk. The fact that he's mobile is a big plus and while he was here he was very professional and gained my full confidence with his work. He's also a nice person with a great attitude. read more

My Jeep had some issues with a speaker not working. Dave came out and within minutes found some loose cables under the dash. Very professional and quality workmanship. Took the time to straighten out the mess of wires and got everything working great. Very responsive and polite. I will be using his services again in the future. read more

David's work and how he communicates to his customers is on a different level compared to similar businesses. From the start when I was requesting quotes, I asked 6 other businesses. Two didn't respond. The other three had that did respond had no other recommendation and a "as low as" price quote. Of course the quote ended with "come in so we can better quote you". David immediately started asking probing questions what I actually need. I thought I could get away with speakers with good mid range bass but he recommended a couple subs within my price range. His recommendations was followed up with an invoice so you arent surprised with those surprise/hidden charges that happens in those auto shops. Davids installation was flawless and the speaker works great. He knew my biggest issue was taking up space in the trunk so he recommended a rockford fosgate 10inch sub that is easy to take out if I need more room. Already gave a couple of his business cards he left with me. read more

Great service from a very friendly and helpful owner David. Had a two channel dash cam installed and David arrived prompt and on time, did a thorough job with the finest of detail and cleanliness.

Thanks for your stellar work! read more

I highly recommend him for car stereo purchases and installations along with other automotive projects. You won't be disappointed with 12 Volt Technologies. A+++++ read more

David was super responsive to my requested quote. His bid was on par with other local shops but the great thing about 12v is David comes to you! On time, with a courtesy text the day of service. Easy to use appointment tool and don't be concerned about the 60 PayPal down payment. It was taken off the bill as promised. When done David provided a full explanation of the completed job, did I also mention he does a before systems check which is good for both his protection and yours. The new alarm works perfect and now I finally have keyless entry. Thank you David. read more

Had David install a new head unit in my truck. He arrived on time, gave me a fair quote and did an excellent job. Really a professional experience. He wired up a front facing camera and was meticulous in testing everything before he was done. Highly recommend. read more

I just had David install a backup camera on my Nissan nv3500 camper van. The install was perfect and looks super professional. Was great that he comes out to the customer instead of having to drive somewhere and I really appreciate that he stands behind his work with a lifetime guarantee. I had some other questions about my van electrical system that he was happy to answer and I may have him come install a DC to DC battery charger for my lithium battery setup in the future. I highly recommend 12 volt technologies for your cars electrical needs! read more

Don't hesitate to hire this guy! Fantastic service, super knowledgeable. He has installed a 4 channel amp and an alarm for me on an old Land Cruiser with no issues. Goes above and beyond to get the job done clean and right. Great prices as well for service that comes to you. Highly recommended. read more

This was a great investment. New sound system and back up camera in a 2001 Yukon. Everything went perfectly. The technician was on time, was amazingly brilliant with every step. This is an amazing business owner. He is friendly and extremely knowledgeable. The pricing and options I was given were exactly what became a reality. Highly recommend this business to anyone wanting to upgrade their vehicles technology. Can't say enough positives to describe the experience. Every penny well spent. read more

Couldn't be happier with my experience. David installed a new head unit and fixed the installation errors made by a previous shop. Also, not having to leave my home to get my car stereo worked on is priceless--especially with this pesky pandemic going on. Speaking of: David was very professional along those lines by always wearing a mask and gloves. He also admittedly has a passion for this line of work, so you know that he puts his heart into it and are guaranteed to receive some quality service. I know I did. I'll definitely be hiring David again for my next project! read more

Absolutely FANTASTIC! Contacted David via Facebook about getting a remote start installed on my old truck.1st I called dozens of shops to see what they would charge for a SUPER BASIC remote start with lock/unlock. Man, I got prices from $250-$500! 12VTech BLEW THEM OUT OF THE WATER! PLUS the price quoted was for him to come out to me! No need to wait hours for my truck to be done. All me car install items will be done with David from 12vTech! Thanks again man! read more

Tech came in van to my home and installed an excellent new stereo in my F-150 in my driveway in about 1 hour. Then he took time to show us how to use it. Superb service! read more

David is a consummate professional in all aspects of his business. He is thorough in explaining all of your options. He offered me three options and recommended the most practical one for my situation, not the most expensive. He isn't pushy or aggressive, he truly cares about your wants and needs and most importantly, your satisfaction. He recently installed brand new speakers in my truck and they sound great. He arrives on time and does what he said he would do. He was on time and he was also willing to go the extra mile and fix somethings that weren't his fault or of his concern. He communicates well via email/text and accepts forms of digital payment (huge plus). I wouldn't hesitate to recommend David to anyone. I look forward to working with David again. read more

Hands down the best, no bs, no hassle just an extremely knowledgeable person with a great personality and a great business. Thank you for fixing all of my years of taking the car to the wrongs guys. The online schedule is by far the easiest way to set up your appointments. Highly recommend Twelve Volt. read more

Great quality work, on time, super clean in how he works in the vehicle as well. Really liked the experience and this is my third install through David. Top Ranking. read more

I talked to David at a car show and he was really friendly,BUT when I called the next Monday there was no answer so I left my contact info. David did not call back at all. I waited a week and tried again thinking he just forgot to call me. I called and got his answering machine, it has been 3 days since that call. David has NOT CALLED BACK!!! not very inpressive for a young business. I was hopeing David was the real thing NOT!!!! read more

David, wanted to follow up with you and tell you how happy we are with the boat. For the first time we we're the ones running the music all weekend while on the sandbars! Stereo never has sounded better. Thanks again! read more

Best of the best in the area, look no further! I've started looking for someone to come over my place and install new car stereo. After back and forth with several Car Stereo specialists around San Diego I made a choice - and I was absolutely right. David is a real professional! He is quality driven service provider and did top notch work installing new radio on my SUV. I liked that all the wires have been soldered, not crimped or kept together by some "magic". He was nice to chat and most importantly he does enjoy what he's doing. read more

David replied extremely fast to my questions and was able to work on my stereo the next day! He was on time and quick. I have had my new radio for a week now and everything sounds great! He did a very job and I would recommend him to anyone looking for a replacement of their radio. read more

David does outstanding work. He has done 3 different dash cam installs for me including my most recent one where he installed a custom on and off button since the dash cam didn't originally have one. He is an expert in knowing the electronics for your vehicle and can do some amazingly creative work. The best part is he comes to you! I've used Best Buy and other vendors in the past but David is by far the best in San Diego County! If you need the best of the best for your dash cam or other needs, this is the place to call! read more

David was early and finished the job within his estimate of installing a replacement headlight on my 4Runner. Excellent work, David! I'll dbe sharing your name with friends, neighbors, and family. read more

David was phenomenal with my install on a very complicated and time consuming project with my 2016 WRX. His attitude and genuine care for the customer, product and experience was the best I have come across from a Audio install. Have no concerns about your inquiries, he'll take great care and guide you appropriately. Can't wait to recommend to all my friends! read more

My highest recommendation for Twelve Volt Technologies. We had an after-market Bluetooth Handsfree Kit installed in approximately 1 hour (at our house--super convenient!!). David is extremely professional. The online booking process is great and the entire process is seamless. read more

My second review- I recently had David out a second time to install a Viper security alarm system on my same Honda Accord LX. Again, he arrived on time and completed the installation in the specified time. Another flawless experience. His prices are lower than competitors and he comes to you! I've already recommended him multiple times. It's a no-brainer. This young man is service oriented to what your needs and wants are and after explaining different options, let's you choose what best suits your needs with different price breakdowns. NO pressure to purchase a more expensive product. Another 5 star review! read more
