Custom Audio & Electronics

Automotive audio system upgrades are a great way to enhance the driving experience and improve the sound quality in your vehicle. Whether you’re looking to replace factory speakers with aftermarket speakers, add a subwoofer or amplifier, or upgrade the head unit, there are a variety of options available to fit your specific needs and budget.

Aftermarket Speakers

One of the most popular car audio system upgrades is replacing factory speakers with aftermarket speakers. These speakers are typically higher quality and can handle more power than factory speakers, resulting in improved sound quality and volume. Aftermarket speakers also come in a variety of sizes and styles, making it easy to find a perfect fit for your vehicle.

Subwoofer Enhancements

Another popular upgrade is adding a subwoofer to enhance the bass output and give a more dynamic and powerful sound. Subwoofers come in a variety of sizes and styles, including sealed, ported, and bandpass enclosures, and can be powered by an amplifier for even more output.

New Head Unit

Upgrading the head unit can also significantly improve the overall audio experience. A new head unit can have features such as a larger display, more options for audio sources like Bluetooth, USB, or even Streaming. It can also have the capability to connect to a smartphone and access the phone’s music library and streaming services.

"Highly recommend them."
I have an older F 250 like new. Had Billy put new stereo, alarm, keyless entry, back up cam etc. Everything was perfect except the key FOB. FOB kept failing. Every time it failed Billy had me bring the truck back in. They finally figured out the issue. Its been almost two years since and keyless entry/FOB, alarm etc working flawless. Billy always professional and stuck it out until they solved the problem. Could not be a happier ending. Highly recommend them.

"Billy and his team exceeded my expectations..."
Went to Audio Toyz to have a JL Audio Stealth Subwoofer, Amplifier, and navigation override installed on my 2017 Cadillac Escalade. I met with Billy and felt very comfortable with his product knowledge and and experience in the field of car audio among other auto related things. Billy and his team exceeded my expectations and added some things that I didn't even think about to add to the vehicle at a cost much less than his competitors. I would recommend Billy and Audio Toyz to anyone in Orange County that's looking for any and all car audio upgrades. Thanks again Billy and Audio Toyz!

"Honest and quick service!"
What do I received? Honest and quick service! The only thing that was not so great was the waiting list time . But considering that they offer services on place with limited staff, it's totally understandable (and also seems they have a lot of work).

"Excellent service from everyone."
I thought I'd add another 5 star review to the Audio Toyz collection. I was originally working with another shop nearby to have some auxiliary power supplies installed. Now I'm glad they never got back to me with an appointment. I found Audio Toyz closer to my house, service far more personable, and they installed the power supplies along with a dedicated plug for my air compressor all for a fraction of what the other shop wanted to charge just for the power supplies. Excellent service from everyone. I highly recommend.

"Will come back here for more upgrades without a doubt."
This place is amazing and filled with knowledgeable people that know and understand what they're doing. I knew nothing about inverters, installation or how they work until Billy (owner) was able to break everything down for me and explain in detail of what I can run when I'm camping. I set up my appointment and the following week they were ready to accommodate me. Excellent job. The work is just so clean and beyond professional and the price is very reasonable. Will come back here for more upgrades without a doubt.
