In the context of this review, I would like to provide some background information. I had a friend…read morewho recently purchased an Alpine ILx509 halo head unit, AudioControl D-5.1300D Series 5-channel amplifier, and a JL Audio 10TW3-D4 10" subwoofer in a JL Stealth Box for his 2023 Toyota Pro. He had previously sold his 4Runner for an F250 and had all of these brand-new and almost plug-and-play components. There were a few Maestro units that I had to use to utilize some of the stock controls. Additionally, one item was defective and brand new, and they were able to get it warrantied. They also had to reflash my Maestro RR because it was specified to a JBL audio system and had to be a non-JBL system. Previously, I had upgraded the stock speakers with Focal all around. I visited CA Car Sounds and informed them about my requirements. It took a few trips to determine if I needed any additional components that were not already installed. They provided me with a quote, which was reasonable given the complexity of the work. They mentioned that they would need the vehicle for 1-2 days, which was acceptable to me. I wanted the work to be completed without any rush. My specific needs were to have the amplifier bolted to a plate under the passenger seat and to avoid bolting the amplifier to the floorboard if possible. I also wanted to use the same SiriusXM stock antenna on my vehicle and retain my stock microphone as well as the steering wheel controls. I was somewhat apprehensive about how the setup would sound, but I was assured by Raymond, Austin, and others that I would not be disappointed with the Stealth box and the subwoofer. When I picked up my vehicle, Raymond accompanied me through the controls and demonstrated how it sounded. I was thoroughly satisfied. Everything looked and sounded excellent. They met my needs and addressed my concerns. The quality of work they put into customers' cars is exceptional. I would like to say thank you to Raymond, Austin and their installers

I worked with California Car Sounds to plan an installation of Focal speakers in my truck. We…read morediscussed the setup in advance and agreed on a specific product and installation plan. When I dropped the truck off and later picked it up, I was told after the fact that they had installed a completely different set of speakers because the Focal speakers I had purchased were back ordered by about a week. Instead of calling or texting to ask whether I wanted to wait or reschedule, the shop decided on its own to install a different brand and type of speaker without my consent. This is not acceptable. As a result, I had them remove everything and return the truck to stock. My weekend was spent shuttling the truck back and forth, the door panels were removed twice, and I am left exactly where I started weeks ago except with wasted time and frustration. What is hardest to understand is the decision making process. There was no phone call, text, or email before making a material change to the agreed upon work. Installing a different product without customer approval is baffling. Unfortunately, I will be taking my business elsewhere.

They ordered the part for me and were very transparent on what would best fit my car without trying to up charge me. 3-4 weeks later they took my car in to install the part and the guys working were equally kind and also showed me how to use the CarPlay. It works so well and I'm truly so happy as this has been a game changer in just the one day I've driven with it so far. It definitely bites into your wallet but the price was fair for Bay Area level. I feel like at mechanic shops and places like it can be intimidating and people will try to up charge if you're a student or just not knowledgeable but I never felt that way here. Would definitely come back for future services!

They took the time to explain everything, answered all my questions, and never made me feel pressured. The install was super clean and professional, and the sound quality is unbelievable. Everything sounds crystal clear and the bass hits perfectly. You can tell Mike and his team take a lot of pride in their work and treat your car like it is their own. What really stood out was that even a year and a half later, when something sounded a little off, Mike was there for me right away and made sure everything was taken care of. That level of customer service is hard to find these days. If you are looking for someone to upgrade your audio system, I highly recommend Mike and the team at Top Notch Tunes. Great customer service, great work, and great results.

I paid this installer $150 per hour to install my car audio system. While the system functions, I…read morewas disappointed with several aspects of the installation quality and attention to detail. The amplifiers were mounted inside the wheel well area, but when it came time to reinstall the trunk floor cover, it would not sit flat because the amplifiers were mounted too high. Instead of redesigning the installation so everything fit properly, the subwoofer enclosure had to be forced into the trunk, leaving a noticeable hump in the trunk floor. For a professional installation, I expected all factory panels and covers to fit correctly when the work was completed. I am also concerned about the amplifier placement because the amplifiers become very hot after driving on warm days. While I understand that amplifiers generate heat, mounting them in a confined area with limited airflow does not seem ideal for long-term reliability. Another concern is the grounding configuration. The capacitor was grounded directly to the battery, and both amplifiers were grounded through the capacitor rather than using a local chassis ground. While there may be technical reasons for this approach, it was never explained to me, and it differs from what many installers typically do in trunk-mounted systems. Better communication regarding the design choices would have been appreciated. Overall, the system works, but the fitment issues, equipment placement, and lack of attention to the finished appearance left me disappointed. For the price charged, I expected a cleaner installation, proper fitment of the factory trunk components, and a more professional final result.
