Francisco is awesome! I just came by for first time regarding a car alarm and he knows his stuff! But also hes so kind and humble! Will be coming back to get alarm fixed and looking forward to using their services for future car audio stuff!

This place is great!! They took my car from squeaking to bumping 😁Great service and extremely Fair prices! Ill be taking my other car back to them ASAP to get a new head unit and a sub. Dont forget to ask them about the awesome rear view mirror/cam they have, it looks amazing!

This is my go to stereo spot!! They have everything you need to make your car sound amazing.They also install alarms and have some really cool new tech to keep us safe out on the road!By far one of the best stereo places around!

Great family business. I got a fair price for the labor on my stereo

Went here to find some speaker grille covers for my car, the owner hooked it up he got me everything I needed and made me feel like as if I was a recurring customer and this was my first time here. If you want to be treated right this is the place for you. Amazing customer service.

Horrible wireing job. Had to get it fixed and done right by professionals. And still charged labor like they did it right. Horrible work....... No I was told there is no need to run another power wire by you for the sub and there was another way.As I am not very knowledgeable on the wireing and all that I took your word for it.. So took it to a very reputable shop and they shown me all that was wrong with this and had to fix it and do it the right way... and you guys never shown me wat work u did on my car before i left as you left early that day and you did not work on my car....When i got home and took out my seat and thats when i seen this horrible job if I knew this was how it was gonna be done I would of said no thanks. And you guys had the nerve to charge 125$ labor for this joke of a job

Best Shop hands down. I have known these guys for close to 8 years. From the small shop they had to the one they are at now. I have had multiple cars done by them over the years. Today i took my wifes 2009 pathfinder in. We got a Alpine touch screen radio, a back up camera, a new Alarm system, and a set of new LED head lights. My wife was super impressed and absolutely loved the out come. I always love and appreciate the high quality of work they do there. I have plans to bring it back and have all speakers and tweeters changed along with they building a custom box to add a sub. Thanks again guys. Appreciate the hard work, quality of work, and dedication you have to your business.

I was very pleased and had a great experience in doing business with Francisco. He was very easy to do business with, and they do a great job.

I took my truck in to have them install a power inverter and they did an amazing professional job. I was beyond impressed with their work and would highly recommend this place. These guys surely know what they are doing and how to do it.

If you know car audio, then you’ll know these guys know what they’re doing. Best in so cal hands down

This brothers are beyond great! I love their work. They take care of your care and give lots of options and ideas on how to make your car sound better and look better. They are very careful in small details and do an exceptional job. Besides being super friendly, they are not pricey at all. I definitely recommend Glendora Auto Sound. Thank you guys!

Excellent customer service and prices!! Definitely recommend!!

Very helpful.... they fixed a bad alarm install I got from a different shop in less then 20 mins... don’t go to any audio shop go to this one you will not be Disappointed.. dudes know what there doing.

Prices are reasonable. They didnt try to upsell or recommend unnecessary services.

These guys did right by me. Another large audio installer couldn’t get me an appointment for three days, so I called these guys. They got me the in same day, had me out within an hour with a new radio install. Good price, great customer service, everything works great, highly recommended!😀👍✌️✝️.

Just visited today and was greeted professionally. Was offered a range of estimates for different products, all offers were honest and fairly priced. All in all, Im a very satisfied customer!

Excellent, courteous service at a fair price.

Great work done here

These guys are professional and do great work. They fabricated a custom dash kit for my headunit and set up 6 new speakers, 2 amps, a sub and DSP. Took a little longer than expected but their work is clean and my system sounds amazing! Very friendly and great customer service. Highly recommend

Great place if you are looking to upgrade sound systems car headlights etc. I totally trust this guys since the first job they did to me I keep on going back. 👌

Excellent service and knowledge. Unlike other installers, these two bothers won’t pressure you sure into buying something you really don’t need. This is my place for all types of installation from now on.

Saw this in the internet and stop by because he was close and had him look at a radio that a friend put in that doesnt work and he said he would check it out and get the right box and he gave me a very good price and was very very nice

Great people, super excellent service,very satisfied.. great job guys...
