Why leave your car at shop when you can have an expert install at home. David had excellent communication, called to check if ok he could come 15 minutes early and did expect difficult install quickly. The best. Thank you David read more

David approached my request for a quote with 3 possible options (detailed w. exact model, the relevant differences, labor and equipment costs, and total amount it would cost). That alone made me want to go with him. He has an efficient scheduling system, followed up with me, showed up on time and did an excellent job installing Apple Car Play in my 2012 Prius C. Since he is Mobile, he came to my work and worked out in the parking lot. I did not have to take any time out of my workday to get it done, and was able to interact regarding a couple of his questions during the install. Highly recommend him! read more

Second time used. Fixed a backup camera issue that another shop screwed up. Very reasonable and will use again. Gave me options which I like. Referred to friends. read more

Awesome job and thank you for answering my questions. I will be doing more business with him in the future

You won't find a better mobile installation service! David provided great customer service, was very helpful, on time, and got my Viper alarm system installed in my truck in less than 2 hours in my driveway. Highly recommended. read more

Just wanted to say thanks to David for the awesome job he did on the installation of my Touchscreen stereo. He was on time and very down to earth and friendly and easy to talk to.

After reviewing multiple car stereo places, I am very glad I choose David to help me out with my car project, as he was very reliable and did an amazing job. He is awesome in what he does, and very quick in communication. If you are questioning your multiple ideas and trying to make a decision, do not hesitate to ask him and he will definitely help you decide and pick the best option for your project. I strongly recommend him, and I will definitely use him for any future car stereo projects come my way. read more

I just had a service visit from David at 12 Volt Tech. Called this morning to report a problem with my car alarm. He came out today and fixed the problem. He's super friendly, was on time, efficient, and knows what to do to fix the problem. I won't hesitate to call again if we have a problem! read more

David is the man! From start to finish, everything was professional, friendly, and I never felt pressured. I couldn't be happier with my new stereo. He helped me choose a new setup for my Civic and the system is amazing. He went out of his way to make sure my installation was clean and that I was happy with how everything looked. Can't recommend him enough. read more

David is very knowledgeable and honest. He showed up on time and walked me through what was going on with my car. He provided me a copy of my diagnostic report to share with my mechanic since there were no audio issues he could find. I would definitely consider giving David a call for your audio/electrical needs. Definitely a credit to his profession. Thank you David. read more

David did a great job repairing my 10 year old alarm system. He not only took care of all the issues I had with it, he was able to add a remote start feature to my existing remote. No more chilly starts for my early commute! I will recommend his service to anyone in need. read more

David was timely, knowledgeable, and delivered. Really can't ask for more than that. I had a set of components installed and migrated a single speaker from the rear to the front as a result of blowing the previous one. It's great to have someone focus on just your request as opposed to having to leave your car in a shop for days on end and painfully slow progress. Highly recommend his services to anyone that doesn't require a total custom job. I'll be using his services in the future for sure. read more

The owner, David, just installed a new radio and backup camera. Excellent: On-time arrival, knowledgeable, friendly, clear explanation of the choices and issues, reasonable prices, clean and neat installation. He hit some unexpected challenges while installing, but he did not charge extra to solve those problems. His use of email and online scheduling system saves my time. read more

It was great to work with David again. Just a few months after he installed a new stereo into my 2006 Ford Explorer, we decided to find a more reliable vehicle. I contacted David, and he was out within a week, right on time, to move the stereo from the Ford to the Chevy Avalanche. He was kind and smiling, and even willingly chatted with a lonely little neighbor boy that hangs around our front yard. Thanks again. read more

David really provides a valuable service for those looking for quality car electronics work. David was able to cut metal from my doors to install some specific mid-bass woofers I wanted placed in my doors. He also installed midrange speaker pods on my pillars. As well as a rear view camera and rear view mirror screen for it on my 2016 Honda Civic. He followed all my requests to the T. Best part is that he was able to do it while I was at work. He accomplished all this in my work parking lot. Very convenient! Thank you David for your hard work. read more

Excellent service. Twelve volt technologies had great communication on appointment time and follow up reminders. David was able to get my new stereo system tuned in and sounding great. Quick and knowledgeable. read more

David was awesome, a true find! He installed a two way radio in my jeep. Scheduling was easy, he was in time, and the work product and value were great. Highly, highly recommend and will be using again. read more

I am so happy i gave them a call. David did the most professional install of my system that i had ever seen and had done to any of my vehicles. His prices were cheaper than a bunch of other places i checked out, and he comes to your location no extra charge! i set up a quick appointment and he communicated extremely well when i was describing what i needed done and was on time and installed my subs and amp quick. Thanks for answering all my questions, letting me watch and explaining everything as you went on!! Will definitely be returning soon for the speaker install!! read more

I had angel eye rings and contacted many shops for install which weren't willing to do it. Luckily found David in the process, he is very knowledgeable and passionate about his craft. Was very professional and does high quality work. Will definitely reach out for future projects. read more

Very, very happy with David and Twelve Volt. Excellent communication, professional and personable, and did a fast and efficient install at my work. The vehicle (and stereo) were a surprise gift for my wife so the mobile installation and the professional insight into options was awesome. He gave me several options and we ended on a system that could be upgraded in the future if needed. Besides that, he helped us diagnose a (dealership installed) alarm issue that was completely unrelated to the stereo or the install. I would not hesitate to recommend Twelve Volt to all of my friends, and I'll be calling David for my next car audio install! read more

Thank you David for a great job. You even figured out my older car issues. Highly recommend you.

David is awesome! He was extremely quick to respond to my initial message about getting a powered subwoofer installed in my car. His work is outstanding. The install was super clean and there were no issues. His prices are extremely reasonable. The best part is that he's mobile, so I didn't have to worry about dropping my car off at a shop and finding a ride or sitting around a shop for hours. I lounged in the comfort of my own home while he did the installation. The subwoofer sounded so good, and he did such a great job, I ended up buying the same powered subwoofer for my other car and had him install it. read more

I reached out to 3 different companies before i decided to work with David on my project. I wanted to replaced the stock HU on my 2017 jeep JKU but with few very detailed concerns about the process and the installation. David knew exactly what i wanted and was able to provide me with all answers to addressed all my concerns. He showed up at my work 20mins before our appointment time and waited till i was ready. He completed the work within the time frame and even helped fixed some minor problems with my light bar(wiring problem). I'm very pleased with his work and communication through the whole project. I will be referring him more business in the future as great/reliable mobile auto installer are very hard to find. Thanks again! read more

See all

The front speakers in my 06 Sequioa were blown and I wanted to replace them. I didn't want to spend much since I just wanted to have if not the same sound as factory a little better. Normally, I would do something like this myself but after watching some DIY videos for my car I decided to have a pro do it. Apparently, my car has an uncommon front speaker size (7") for budget speakers so replacing them with the next size that fit would need some customizing to fit right in the door. After doing a Yelp search I found 12 Volt Technologies. Not only was David, prompt with his responses to my questions he came in at the lowest price. Best of all, he's mobile so he comes to you. He gave me options from entry level to high end. After doing some shopping, I decided to go with the mid-level upgrade. Scheduling was easy on his site and you get friendly reminders. David arrived on time at my house and he opened with 'I had a problem with my supplier and the speakers we talked about were on backorder'. My initial thought was, I'm probably going to get a lower end model since he knew my budget. I was wrong. He said he paid the difference to get the next level up which were the 7" speakers and wouldn't charge me since we had agreed on a price. How awesome is that!! That's great customer service. I asked him if it was ok for me to hover and watch him work because I myself like to learn. David welcomed it and was very nice about answering all my questions. As I watched him work and we talked, I could tell that he's very passionate about what he does and truly enjoys his craft. He even taught me a NASA splice solder technique. His install was clean and he is very meticulous making sure everything works properly before buttoning everything up. In the end, I was super happy with the install, the sound, and David's work. If I ever decided to expand or upgrade, I know who to call. Thanks David!! read more

I found this company after sending out some requests for quotes via Yelp for a broken antenna on my 02 4runner. I was shocked by some replies I got back and a majority wanted $$ even for a quote. Then David emailed me, figured out options, sent me quotes for all of them, was so nice and willing to work with my schedule and didn't pressure me in anyway about my choices. I have no clue if this was the "cheapest" option and really don't care because David was awesome and so helpful and installed my new antenna in like an hour. I'd give him like 20 stars if I could :) read more

David was awesome with my head unit and system installation on my restored 1963 Cadillac Eldorado convertible. His mobile service was on time, professional, clean, and courteous. I was extremely pleased, and will be notifying members of the classic car community about his great services. Highly recommend, and I will be using him again for future audio needs. read more

David worked with me to come back and modify the wiring on a prior head unit installation to allow the mirroring app to work the way I needed it to. Once again, he was easy to coordinate with over email, appointment setup was easy via his online site, he arrived a few minutes early, got the job done without incident and there was no complications with payment. Knowledgeable and friendly guy who is trying to build his business. I'm recommending him. read more

It was a pleasure doing business with David, who is very friendly and knowledgeable about the audio industry. His mobile service was convenient for someone who works during the day. He showed up on time and was very responsive to all my messages leading up to my appointment. I hope to use him again soon for upgrades. read more

It is rare to find someone so intelligent, personable, professional and knowledgeable in one person. David Talman of 12 Volt Technology fits the bill. I had an extremely difficult installation because of a bad prior job that screwed up my audio electronic system. David analyzed the problems, and fixed them in a reasonable amount of time for a good price. And, now everything works perfectly. For my next system, you can be assured, David will be the one to do it. read more

David did a superb job, starting with emailing us before the job to make sure we had the rights parts on hand to do the job right. He showed up on time, did a very professional job on the install and reviewed with me all the details of my new stereo once it was in. Fast friendly and professional, and cheaper than having Best Buy do the install!! What more can you ask for? Two thumbs up...highly recommended and would not hesitate to use again! read more

David is a real professional. He got the job done in good time with my truck, and has great customer service skills. This is the 2nd time I used his services. If and when I have a problem with my truck or Jeep I'll be calling him again. read more

David arrived early and communication was easy and direct. He was able to diagnose the problem (poor installation from Stereo Depot) and gave me a number of different options to solve the issue. He had everything fixed and put back together within an hour and a half of arriving and walked me through everything he was doing while answering all of my questions. It's awesome that he comes right to your house. After dealing with some shady audio dealers in the past (Stereo Depot), I will be using David and 12 volt for all of my future audio needs. I highly recommend his services. Thanks David! read more

Outstanding service! David recommends systems for your goals and budget. Top notch credentialed tech. I've found my perfect installer. Can't recommend him enough. read more
