    Helix controller damaged and inoperable
    Nick K.

    I thought this was gonna be a good little shop. And at first it was. I went to talk to talk to AJ about doing a tuning and time alignment on my car with a helix ultra processor. He said they didn't have a lot of experience with it, but they would do their homework and get it done, and get it done Well. I made an appointment for the following week at 9 AM. I showed up at 9 AM, but the installer that was doing the work, didn't show up until 10 AM. I gave him a quick demo of my set up, how everything worked, where it was located, And a basic rundown of the controller interface. Everything working and perfect. 3 1/2 hours later, they notified me that they couldn't get it done. When I showed up to pick up the car, they had damaged the controller interface, making it in operable. It was fine when I dropped it off and when I demoed it to the tech. But it was broken when I came to pick it up. I had to go round and round with AJ about Responsibility for the damage. He didn't want to take responsibility for the damage that was done to my car while it was in their possession. Ultimately he came out after making a phone call and essentially threw $200 at me to replace the controller, and all but walked me out the back door. Leaving me, responsible for ordering it, and getting it installed. Awesome! If you're looking for a simple speaker install, they can probably handle it. If you're looking for something more than that, I would look elsewhere if it were me.

    Dash cam installed with no ugly wires hanging

    I received a dash cam for my birthday and didn't know much about the installation process. I requested quotes online and Advanced Stereo Motor Sports was able to provide me with the service that I needed in just over an hour. The shop has displays of stereos, and equipment as well if you don't have the equipment on hand (like I did).

    Came in for Android Auto for my 2013 Acura RDX. They provided me a great wireless option! It works flawlessly! Google navigation, pandora, more apps all integrated into car's original 8" screen! This car is now modernized! Best part is Al, the owner, beat other Riverside stereo shop's pricing by about 100$. He beat Advanced Stereo - the other Riverside shop (original one) by $200! Would definitely reccomend!

    10/10. Got a head unit and small sub installed in my son's car. Reasonable cost and great service. Excellent work done. Whole process was smooth and install only took a couple hours. Shout out to Al and the boys. Very professional and knowledgeable. Will def be back!

    Great Deals and services. So very outstanding…read more Knowable to people's individual needs and expectations. I'll recommend you go to them first and last.

    I was once a happy customer, but unfortunately my experience with Advanced Car Stereo has gone…read moredownhill. I had a system installed in my Polaris Slingshot about a year and a half ago, and since then I've had to return to the shop at least 6 times for ongoing issues with the equipment. I don't live nearby, so every visit meant arranging and paying for an Uber after dropping off my vehicle, which has been extremely inconvenient. I also want to be clear--I spent a lot of money here. Not just a small amount, but a few thousand dollars. For that kind of investment, I expected quality and reliability. Instead, I'm now being told my equipment is basically no good anymore. So what does that mean--I'm supposed to spend thousands of dollars every year and a half just to keep a working system? That's unacceptable. The biggest issue is the quality of the equipment. I was told I was getting aqua/marine-grade products, but that clearly hasn't been the case. The system has not held up the way it should, especially for what was promised. Customer service was also disappointing. When I asked to speak with the owner/manager, I was given multiple excuses before I was finally able to speak with him in person--and even then, it was excuse after excuse. Instead of solutions, I got no real accountability. On top of that, the initial inspection and diagnosis were not thorough. I was told over the phone that they would "call me back again after doing a more thorough inspection," which raised concerns about how carefully things were being handled in the first place. Lastly, the warranty they promote doesn't seem to actually exist in practice. When issues came up, there was no real support or accountability. Overall, I'm very frustrated. What started as a good experience turned into repeated problems, wasted time, and added expenses. I would not recommend this shop based on my experience.

After four hours we had a working LineOutConverter, capacitor, epicenter, amplifier and subwoofer. The cable work was dealer quality. He installed most of it within compartments of the trunk which is far more attention to detail then I requested. Worth every dollar plus a tip. Will come back for a custom fabrication. Thank you!!!

It's nothing against them, I was always satisfied with the results and products but just the experience I had at Azteca was just that good that they now get mine and my family's business from now on. The owner Tony is very personable and friendly and accommodating. We had a nice conversation the entire time he was working on my car as if we were friends for years. Most importantly he was diligent, knowledgeable and the price was more than fair. I'll be going right back in a few days to have them do another job. This place is a hidden gem and 5 star spot, I highly recommend I may have prematurely misjudged this place after one experience. I went back to have them do a system installation and the guy never showed up and would not even answer my calls, after scheduling an appointment with me for the very next morning. I was there at the agreed on time and waited for an hour and a half before it became obvious he wasn't going to show or take my calls. Business must be pretty good for him to treat customers so poorly but he won't be getting anymore from my friends or family and this can be considered a formal rescinding of my 5 star review. It is now 1 star.....
