I have a base-model C6 Corvette and wanted to give the audio system a little more punch. I left with way more bass than I thought I needed and, more importantly, spent way less than I expected. The whole team was friendly, knowledgeable, and never made me feel like I was being difficult. If I had a garage full of cars and unlimited money, every one of them would be coming here. 10/10 -- highly recommend.

Shopped around but went with them because I was assured a good price and expedited service. Those things are important. Single mom with a TIGHT schedule. I gave the down payment on Friday and was promised it'd be done by Sunday. Sounds great right?!?! NOPE! It ended up taking a couple of weeks. Long story short, products weren't in stock when I was told they were, wrong parts were ordered, and timelines were miscommunicated. Soooo frustrating. BUT LET ME TELL YOU HOW THEY TURNED MY FROWN UPSIDE DOWN. The gentleman I originally dealt with was let go (he was bad for business)....Damian the great stepped in and worked his magic! The manager drove to LA to pick up the part I needed, Larry prioritized my vehicle because I had already been waiting and Joshua finished up the job when I was able to return. These gentleman went above and beyond to make me the customer satisfied. I am glad I gave them a chance. Stuff happens, I get it but not all companies are willing to take accountability the way Advanced Car Stereo did. Thank you guys for taking care of me!!! Go with these guys, they will not disappoint.

I was recommended and subsequently introduced to JR by Chris Tusow over at SubiWorks / RFC…read moreIndustries when I mentioned I had a showroom condition 1983 Datsun 280ZX Turbo that needed some pretty specific electrical work. I had a really negative experience with another auto electrician near me and Chris has been my go to mechanic for all things Subaru and has become a friend as well, so I asked if he knew anyone willing to work on my classic car. He gave me JR's phone number, so I gave him and call and booked an appointment to bring my car in the following week. I live about 50 miles away, but I'm not afraid of driving long distances for solid work. I also own a business so I love connecting with other business owners who are really good at their trade / industry and learning about how they handle their workflow. JR was super kind and kept me informed the entire time. Carlos, one of the employees is awesome too. They helped me with everything I needed to get done in terms of electrical on my Datsun...from backlights, censors, gauges, reviving a working OEM vintage tape deck, and much more. The whole process took about a week. JR and Carlos also installed a new dash cam on my Subaru Forester. I was able to hang out at the shop, get to know them, meet Coco, and chop it up with them. If you need electrical work done, go see JR and Carlos. Thanks again for all of the help with my vehicles and being awesome people.

Completely unprofessional and now I have to drive back over to get my deposit back. I asked to speak to the owner and he has yet to call. Would not recommend this place.
