    Took my 2020 Porsche 911 here to get the sound system upgraded. Felipe suggested changing the…read morespeakers and adding an amp, both from JL Audio. Total cost was about $6k and I went ahead and did it. After I got the car back, I was disappointed as the sound quality was about the same as before or perhaps marginally better. Additionally, there was rattling in the door panels and I would also hear an occasional popping noise. I mentioned both of these to Felipe. Additional sound deadening was added for the rattling, but the popping noise couldn't be resolved. Even after the additional sound deadening was added, there would still be rattling in the door panels. A couple months later, I moved down to LA and decided to bring the car into another shop down in LA. The shop informed me that the speakers used are JL Audio C2 speakers which are OEM replacement speakers. They told me they are not sure why anyone would replace the stock speakers with those as they are not much of an upgrade. Additionally, the new shop said what my system needed was a Nav TV device to convert the audio to digital output as well as add a DSP (digital sound processor). They said it is clear that the previous installer (i.e. Felipe) does not know much about car audio given the recommendations that were made. To make matters worse, when the new shop started working on my car they informed me that a number of things were broken such as the clips that hold down the center piece of the backseat and other clips throughout the car. The feedback was that the overall work was shoddy. I trusted Felipe with my car and the net result was a sound system that wasn't an upgrade. I spent $6k spent for nothing, wasted my time, and the worst part is I now have damaged components throughout my car. I have since spent an additional $8k on top of what I paid Felipe to redo the sound system entirely. Felipe is a nice guy and it was nice to work with him. He did help me install a dash cam on my other car and from what I can see that installation was fine. However, for car audio systems, I would not recommend Felipe.

    Second time Felipe has done an installation for me. First time work was done under a strict budget…read more Felipe didn't try to up sell me. End result within budget was great. Second installation was equally great results. I made few changes that wasn't expected but Felipe was more than happy to accommodate my requests. Clear and concise communications throughout the process. Simply amazing service.

    I was able to schedule an appointment through Yelp on short notice. They were very responsive and…read moremade the process quick and easy. Initially, I had purchased a 10-inch subwoofer from Amazon and planned to have them install it. However, after listening to one of their 12-inch subwoofers, I was very impressed with the bass quality and decided to go with their setup instead. The employee was knowledgeable, professional, and never pressured me into making a purchase. He took the time to answer all of my questions honestly, which helped me make an informed decision. Although the installation took a little longer than expected, the finished work was clean and professionally done. The sound quality is excellent, and I am very satisfied with the results. I would highly recommend them to anyone looking for quality audio installation services.

    I'll give Precision 5 stars on installation and friendliness. Sayed and Sam, as well as the…read moreinstaller, are all nice guys - courteous, professional. However, the "flat" quote changed to "oh, you need a $100 power harness cable." I understood the need. The amp/sub power cable alone would never reach the battery. But $100 is excessive. Not a showstopper, but a surprise. Second, they charge full tax on labor. Not cool. Didn't hit me until I got home and looked at the detailed receipt. Again, not a showstopper. But still ... Overall, I would recommend Precision. Just know what to expect.

    My brother and I have been going to Guru Electronics for our Car audio & Electronics needs for over…read more20 years. My last car was rear ended & considered a total-loss. I replaced it with a used Subaru Impreza that didnt come with a reverse camera. My mom uses the car alot, so she's going to need the reverse camera :) I arrived 15 minutes before closing on Friday and since I didnt want to keep them after closing, basically told them what model car I just bought, and what I was looking for. Double din head unit w/ reverse camera, and some aftermarket replacement door speakers. They asked if I wanted to keep the steering wheel control functions, which I did... so he mentioned what else I needed in order to keep them functional with the new stereo. He asked if Android Auto / Apple play is important to me, and if i wanted it wired/wireless. This day in age, we want everything wireless and convenient, so I said yes to the wireless feature! I mentioned I was interested in component speakers for the front doors, and he suggested where to install the tweeters, and also told me I would need some mounting plates for the dashboard for the tweeters. This way I dont have to drill a hole in the door panel. All in all... Its nice to have someone ask the right questions to ensure I had everything I needed to complete the installation over the weekend, because I would not have had the tweeter mounts if he didnt ask about my installation. I would like to mention that I wanted to have everything I needed for the weekend installation project, so I didnt check around for lower prices, but when I got home... the "Asian habits" in me decided to check prices on Amazon, and Guru's prices were either on par... or slightly below Amazon's prices! Thank you Guru and your staff for hooking me up! Tip - Bring CASH!!! ;)

    TLDR: Make sure to go inside and around the right for Guru (the owner)…read more The actual labor and installation of the audio is 5 stars. Customer Service is 2 stars... it needs a lot of work. I didn't know what to expect coming here... I waited at the front of the garage for about 15 minutes. There was a guy smirking in the front, doing something with cables, 2 other people working on a car, and another guy going in and out doing some kinda repair work on a truck outside. None of them said hi to me. But I know they all saw me. It was very weird. Finally after about 10 minutes of waiting (I figured maybe the owner was on lunch, since this was about 1pm), I walked up to the smirking guy and asked if the owner was here. Then he just nodded and pointed to the right, which was a very small aisle BEHIND a big stack of boxes. It was very off-putting. But I was here, and I had a time crunch. The actual owner was nice... he asked about my car, and then showed me some models. I made a purchase, and he told me to come back in 2 hours. I walked to a nearby Carls Jr, about 7 mintues away. 2 hours later, right on the dot, I get a call to get my car, and they close sharp at 4:30p. The same guy who was walking in and out (remember fixing the truck), was the one who showed me how everything worked, helped me pair my phone. I paid about $950 after taxes. I don't know if that's a good deal, but everything works well, no scratches around the dash. If it weren't for the unwelcoming first impression, this would be a 5 star for me. I wanted to give them 3 stars, but this is clearly a small business owner. My hope is they read this and work on their welcoming attitude.
