So I was referred here by my employer. When I initially called about replacing my stereo the sales…read moreperson was amazing. Answered all my questions. 1. When I brought my truck in today at 3pm and did t leave until after 6pm I was a little irritated because I was told last week it would take an hour. 2. The salesman who talked to me on the phone last week didn't say hello or give me the time of day(store was empty). He only told me he didn't have the part to fix my back up camera. 3. Salesman and receptionist promptly left at 6pm and I was told the guy installing the radio would come and get me. I would think the salesman would stick around. 4. They shouldn't leave transaction history up on their computer for everyone to see after they tore out of there. 5. The poor guy that installed the stereo was very nice and walked me through all the new gadgets. He was the best customer service I had there in 3 1/2 hours. 6. I truly felt after they got my $ they had no obligation to give me basic customer service. So far the new stereo is pretty cool! Do better Muntz staff.

Yelled...literally YELLED at me for doubting his work. He gets "offended when people ask him to double check his work" and needed a prepayment to take a look and see what might be wrong. Took it to the dealer prior and they told me they couldn't help and go back to the after market install guy. Idk why he yelled at me that the camera HE INSTALLED stopped working. What good is a 1 year warranty if you're gonna make me pay again anyways? Ps - dealer charged me $0 to take a look. Poor customer service and treatment. Would not reccomend. In reply to Bruce - I was hoping my 2nd guy was the kind of guy to fix it. Jokes on me. Thanks for the extra electrical tape!

So here is my long history with Sound World - most of which I kept to myself until recently with…read morethe straw that broke the camel's back. Now I shall tell all. We had Sound World install a home theater system and multi-room sound system in our house roughly 8 years ago. Overall the installation was good until I caught the installer drilling a large hole in the ceiling and stapling a large cable along the entry door from the garage (had they discussed options with me first, I would have informed them that we had a chase installed for the purpose of running cables to the attic). I was also unimpressed when he seemed oblivious to the multiple black fingerprint smudges on the ceiling when he installed the speakers. We later had a receiver go bad which they replaced under warranty. Turns out the replacement was used (I found this out when I was programming it and found someone else's internet info stored in it). Fast forward to 2020. With technological changes since our initial installation, we wanted to make some modifications to our system so I stopped by their store to schedule an appointment. They wouldn't even pencil me into their appointment book (2 months out) without a credit card on file! I can understand confirming payment arrangements prior to sending a technician an hour away, but how about taking care of it with a phone call while verifying the appointment perhaps the day before the scheduled installation date? To be unwilling to even schedule an appointment without a credit card on file was absolutely insulting to me - especially after we had previously spent $12,000+ with them!!! I told them as much and told them I would look elsewhere. Now for the straw.... We needed a new bulb for our projector. It seems it is something we have to order from a dealer so I contacted Sound World early on December 27. I was told someone would get back to me. By the afternoon of the 28th, I had not heard back. After an internet search, I found a company called Jaspertronics. I called them, gave them my make/model number and they knew what bulb I needed within seconds. I received my order from them on the 30th. Jaspertronics provided me with excellent, friendly, and efficient customer service. Those are the qualities Sound World is lacking. 24 days and counting - I HAVE STILL NOT RECEIVED A CALL BACK from Sound World!! I obviously don't recommend them.

Extremely painful Extremely long wait…read moreExtremely unorganized Extremely bad management Extremely horrible communication Extremely unreliable Extremely disrespectful Extremely expensive Extremely corrupt The list can go on but "Extreme Audio" I didn't get. Over 4 months and they still can't get the job done! I didn't ask for anything wildly crazy. I just needed to replace my dead audio radio. I thought supporting a small business would be nice. WRONG! On 12/21/21, I called to get a replacement radio for my car. I was quoted $300. The next morning, I went in to put down 50% deposit. I told them I need my back camera to work. Chris told me I needed to upgrade to a $500 radio in order have back camera. I agreed and put down $400. I was told they will call me once my radio is delivered. Nothing for 3 weeks! Not a single phone call. On 1/22/22, I called to follow-up on the status of my radio. The guy on the phone couldn't find my order. He put me on hold for a long time. When he finally came back, he told me the radio hasn't arrived yet. I'm sure this was went they finally ordered the radio. On 2/4/22, I called again. Still no radio. I asked to talk to the manager, Chris. I was told he already left for the day. I asked that he called me back on Monday. Monday came and no call. On 2/8/22, I got a call to schedule a time to install my radio. We scheduled for 2/11/2022. I thought the drama was over. Not even close! On the day of installation, I was told they didn't know I needed my back camera to work. I reminded them why I upgraded my radio. They said they have no records of such a request. Suddenly, they change their story to needing an adapter to make the back camera work. Since I already paid for labor, I agreed to buy the adapter for an extra $65. I waited for Chris to place an order for the adapter. I was told it would take at least 2 weeks to get it delivered since it's coming from Florida. On 2/22/21, I called to follow up on my adapter since no one called me. Once again, the person on my phone has no clue. He said he will call Chris to get the status. On 3/8/21, I called again to follow up. I was told Chris said the adapter hasn't arrived. Shit! They might as well order the dam part from China! It would be here already! On 3/15/21, I called again to request a refund. I was told Chris is on vacation and I should call back tomorrow to talk to him. On 3/16/21, I called at 1PM and finally talked to Chris. His excuse was that he was on vacation. We scheduled a time to finish installing my back camera the following week. On 3/23/21, I arrived at 9AM to get my camera installed as scheduled. The guy at the front looked puzzled and couldn't find anything scheduled in the computer. He left to the back and came back with a lame excuse that Chris will need to reschedule for tomorrow morning since his kid is sick (I'm almost sure Chris is sitting back there in his little office hiding). Being a parent, I understand about sick kids but it's not that hard to just call and let me know so I didn't have to drive across town in rainy bad weather. I left with no real schedule on when exactly I should come back and they never called me to follow up either. No surprise! This shit show has gone long enough and I have been as understanding as humanly possible. I'm done chasing them to do their job! They have a disclaimer on their invoice stating, "NO REFUNDS and all sales are final.... Anything not picked up 90 days will be sold or thrown away." I'm guessing they want to stall my installation so they can keep the extra money without doing any work, or they have been lying and never got the part to install my back camera. If you can afford to wait months and chase them down like little kids to get "part" of your work done, go right ahead and contact them. My biggest regard is thinking a small business would do a better job and deserves to get paid. I wasted so much time and ended up paying over $700 for a simple car radio replacement. NEVER AGAIN! EXTREMELY CORRUPT!!! Not to mention... the entire experience felt sexist and racist too. Stay far away, women and minorities.

However, after speaking with Matt at Xplosive, I left better informed and confident that I was going to enjoy my experience with his company. From my initial consultation, Matt treated me as an equal, though he knew everything and I knew nothing. He waled me through what would give me the best "bang for my buck". I am no spendthrift, so walking me through an expense I deem a splurge was no easy task for the poor guy. Never did I feel bad about a question. And he used every means of communication, from in person, to email, to eventual phone. All the while, he guided me through the process. And with a time crunch, he even obliged me an early install. My car was dropped off at 9am and completed by 3pm (do NOT hold him to that kind of speedy delivery!). Matt fit the subwoofer and amp addition within my budget and completely the work with aplomb. I HIGLY recommend the novice AND the knowledgeable. Matt will take care of you. Thank you, Matt and Xplosive!

I met these guys at Wisconsin Harley Davidson during the 2018 Milwaukee H-D Rally over Labor Day…read more They installed a Rockford Fosgate TM400X4ad Amplifier and Rockford Fosgate speakers on my 2017 Road Glide. At the time I questioned the use of "Velcro" as an install method for the amp. They told me it was the only way to do the install and make it fit. This week I took the inner faring off to have it painted and noticed the windshield was cracked at the base by the mounting screws. It would be hard to prove in court but I did see them use a drill driver to put the screws back in and I am sure that did not do my windshield any good. I also noticed the amp had fallen of the Velcro and was a little banged up. That explains the rattle I was hearing. After the initial install, I ended up asking for all the extra parts from the kit. They did not use the heatsink or mounting bracket for the Amp. This is a 400 Watt amp and I believe the engineers at Rockford Fosgate included a heatsink because it needs a heatsink. It is a good thing I saved this stuff. After watching a 15 minute you-tube video by Rockford Fosgate on how to properly install this, I reinstalled it correctly myself. It took about 30 minutes. I also noticed that they ran the power wiring over the gas tank rather than lift the tank to rout the wires properly in the factory H-D wire tray. I need to fix that next. I am sure these short cuts saved time but the result was a very crappy install. And let me point out they charged me plenty for that install. I have found no fault with the Amp and speakers, they are a big improvement over the stock Harley amp and speakers. One last tip, the Rockford Fosgate instructions tell you to set the amp to hi pass (this will limit the base). I believe they may be trying to prevent speaker failure. When I reinstalled mine I set the amp to "All Pass" and WOW!! did that wake up the system. It sounds awesome now. The guys at Extreme audio seem knowledgeable and were very nice, but they are taking shortcuts that they simply shouldn't take. They would do well to follow the Rockford Fosgate installation instructions. Contrary to what they said, everything fits just fine under the faring when installed per the instructions. If you have them work on your bike, tell them to skip the Velcro and do it right! Good Luck.

I explained what I wanted and how I wanted it to look. But I later realized I forgot to explain a key detail. Fortunately that detail was not overlooked by the staff. They did exactly what I had wanted anyway. The work was done better than how I explained it and the results exceeded my expectations. I expected to pay more than I did. I am very happy with the quality of the work and with the knowledge and how friendly the staff is. I'll be back for another project later this month. I made it to Extreme Audio for that second project and they did another great job with it. Very impressed. So what do I do? I go ahead and cut a wire by accident. Fortunately I realized what I had done and they fixed it for me no charge. Great service, very helpful and I am very pleased they are around!
