I've been to about 6 different audio shops over the years. I've been over charged, had horrible installs, and even stuff broken. Glendora auto sound is the best shop I've been too. Francisco and his brother always take care of me. Their work is always clean and the prices are great. If I ever have a problem they don't hesitate to fix it. I had another shop ruin a sub box and They were able to repair it same day to work with my schedule. Francisco even came in on his day off to finish up the job. I will never be going to another shop again. Don't hesitate to take your car here. You will not be disappointed. read more

Took my truck to have a backup camera installed and a stereo. These guys did an outstanding job !!! Prices were the best in town. These guys are friendly and very knowledgeable. I will be going back soon for more upgrades. You cannot go wrong with these guys. Highly recommended read more

My first five stars go to Yelp for directing me here in the first place. Francisco is awesome and I would highly recommend this business to anyone. I first went in with a cd stuck in my player. He removed it at a very reasonable fee and I went back for a new stereo installation which he did while I waited. He showed me all the features on new unit and when the Sirius radio antenna shook loose during a road trip, he fixed it on the spot in about ten minutes. No BS with these guys. Go there. read more

Haven't actually done business with these folks so can't comment on their products or service. However, after 2 inquiries and 2 no answers, they don't seem to be worthy of my business so will never know how wonderful they are! read more

I went in after hours and they promptly took care of my car. Fair price. I would recommend them

Put an Avital alarm in my 2015 Tundra, these guys did an amazing job and went above and beyond my expectations! Will be back for speakers and a subwoofer. Thanks Glendora Auto Sound! read more

Best store I've ever been to! Personalized work that's done here is immaculate, Francisco is a professional highly recommended.

I very much recommend anybody looking to upgrade their sound system to come to Glendora Auto Sound. I've got nothing but praise for their knowledge in the car audio industry as well as their profession. I took my 2015 Honda Civic to this place not knowing what to expect. I needed to get my amp and sub installed in my car under the condition that they would keep everything in the car looking 100% factory and that's exactly what they did. I'm definitely coming back in the future for their services. read more

Came to get my amp and speakers connected, quick and simple set up. Pricing was very competitive with past shops I've been to and the 2 brothers provided me good information with respect to some HID's for my vehicle. Since their local, I'll be sure to come back for any future work I may need done on any of my vehicles. Keep up the good work! read more

Glendora Auto Sound - Car Stereo Installation Near Me - Glendora, California

I have a 2017 Honda Ridgeline. This place is very honest and friendly I appreciate the kindness and patience of the gentleman's that helped me. When I asked for pricing and quotes these guys are pretty honest and it seemed kind of high at that moment. That's because they were being fair and truthful in writing me a list of what my truck needed. Unlike places that I've gone to that said " oh you'll need this, that and quote a lower price" only to have more parts needed and charge me more. l ended up buying my own stereo a Kenwood and having these guys install it. They did a very good job and I recommend this place read more

I saw them at offer up and I asked if they do installation on my alarm they did not even respond back to me it so simple to reply by just saying yes or no. But no respond at all. Thumbs down they do want business then. read more

Really good service and professional advice! Took my track Honda S2000 to fix my poor speaker, after he checked my speaker, he said this unit is pretty good and he didn't recommend me to replace new speaker unless I want to do something $250+ high end for only 2 speaker, so I just let him to fix it and tight it , my speaker is back! Really good price, too! read more

As some of the reviewers mentioned, when you see their small shop you kind of want to go elsewhere but Francisco and his brother are great at what they do so don't judge a book by its cover! I took my 2008 Chevy Uplander Minivan to have my roof mounted DVD player installed by them. I was nervous that the headliner would not support the large unit but Francisco assured me that he would get it on there securely. I left the car with them convinced this wouldn't work out well and 4 hours later I was AMAZED how well they did. The DVD player is on there like it was meant to be. Their work was perfect and its on the roof super secure. The wiring work was done perfectly and they work clean! Very Impressed and Super Happy and BTW a good deal too! I will be back for more work on my other cars and I hope you all will give them your business too. read more

I just moved from San Diego to Covina and I didn't know where to get a fair price and honest and professional stereo shop installers. Francisco did an amazing job in my car. He was super honest and didn't offer me to get the most expensive equipment but instead the one that suits me and my baby better. It's hard to keep my son distracted. I appreciate the way they treated me and how friendly these guys are. read more

Great install on my speakers . Wouldn't go to any other shop. Thanks again Glendora Autosound. read more

Took my sons car to get speakers,amp,sub and double din installed. When my car was ready I showed up and all he said was the stereo wasn't working properly, didn't bother showing me what he had done. Then he said I had to pay tax on top of what he originally had quoted me. Got home and realized the subwoofer wasn't even working. Would not recommend! read more

My brother's car had an aftermarket light system installed on his car and one of the light bulbs went out. Francisco at Glendora Auto Sound Stereo ordered him a new kit had it installed the same day. My brother was so happy that he asked me to write the review about his experience since his review is always filtered out by the people at Yelp. So if you are in the area and in need of stereo or lighting needs, please looks these guys up. They are located behind the Arco gas station, next to Bank of America. A+ to them for their honesty and quick service! read more

I don't post all that often on Yelp but in this case I felt that I had to. I was looking for someone to install a small subwoofer in my Jeep. I had already checked with Best Buy and they wanted an exhorbitant amount and on top of that they couldn't get to me for 2 weeks at least. I checked on Yelp on my phone and came across Glendora Auto Sound. I called and spoke with Francisco. He was very friendly and professional and invited me to bring my jeep right over. Installation price was so fair that I decided ask about changing out my head unit. Francisco offered me a used unit for a very good price so I also decided to add speakers. I got all of this work done including the speakers and "new" head unit for the same price that Best Buy had quoted me just to install my subwoofer. The install was done cleanly and quickly. I highly recommend this shop to anyone looking for a fair price on car stereo installation. read more

I found Glendora Auto Sound through Yelp and I decided to give them a shot simply based on all of the awesome reviews they got. I am very happy with my decision!

Glendora auto sound is awesome! Came in for an alarm install. They offered a great price and install was fast. After a couple days of the alarm install, I felt like the sensitivity was a bit high. I drop by the shop 30 mins before they close and explain my situation. They adjusted the sensitivity to my standard. Thanks again GAS! read more

I just had new pioneer speakers plus a radio installed all together into my car for a very fair price compared to the other places in the area, Francisco and his brother did an amazing job, they were very friendly and helpful, they knew what they were talking about, also they made the car look like nothing has been removed, they put the peices back together perfectly and well done, i would reccomend this place to any one that is thinking about getting a sound system for their car, Job Well Done, Extremely Satisfied (: !

I came to Glendora Auto Sound after visiting several other local stereo shops, and ended up buying stereo and speakers from Francisco. Talk about great experience from discussing different options, recommendations, purchasing and installation. I can't thank him enough for the price, quality of workmanship and great customer service. Will be coming back with my other car soon to get DVD player. I would highly recommend this company to my friends! read more

Had some work done the other day. They are great here... as they were installing I changed my mind a few times. Most shops would get upset and give attitude but Francisco was really calm and assured me they would do what ever I want to my car. They are great here, prices good, no pressure to upsale and do great work. read more
