Why Choose Us

Because we’re a family-run crew of gearheads who know exactly what you’re looking for.

For over 10 years, StreetFighter Motorsports has been Phoenix’s pit stop for custom car audio fabrication and speaker box installations. Here’s why.

Locally Owned, Community Centered

Being family-run means we hold ourselves to a higher standard. Get craftsmanship backed by accountability.

Real Audio
Specialists

We don’t just drop a box in your trunk. We design, measure, and tune every custom subwoofer enclosure for your vehicle.

Impeccable Fit,
Every Time

Our boxes fit snugly, panels align perfectly, and wiring is routed cleanly for a seamless, professional look.

Built to Take
a Beating

Our boxes and components are chosen to handle real-world performance, not just showroom demos.

Loud and
Proud

We tune your system to create a true driver-focused soundstage. Don’t just hear it. Feel it.

Premium
Components Only

From the custom-built sub boxes to the amp to every connection in between, we only use components designed to handle full power without clipping.

Performance
Meets Safety

Every installation is tuned to deliver maximum output without stressing your vehicle’s electrical system. Loud doesn’t have to mean risky.

Modern Tech for
Modern Builds

Whether it’s a classic ride or a modern daily, we integrate DSP, Bluetooth, and advanced audio tech into custom boxes.

Drive Through the Custom Subwoofer Enclosures We Install

Does your current setup sound like a muffled radio from the 90s? The right subwoofer enclosure makes all the difference.

Here’s a list of the custom-built sub boxes we install:

Sealed Speaker Boxes

Sealed boxes are airtight enclosures that produce tight, controlled bass.
Best for: Tight, controlled bass for all types of music

Ported Speaker Boxes

Uses a vent or port to move more air, which creates deeper and louder bass than sealed designs.
Best for: Bass lovers who want low-end for hip-hop, EDM, etc.

Bandpass Speaker Boxes

Bandpass boxes place the subwoofer inside a chamber with a ported output section.
Best for: Extreme bass output

Custom Fiberglass Subwoofer Boxes

Fiberglass speaker boxes are hand-shaped to fit specific areas of your vehicle, such as trunk corners or side panels.
Best for: Custom builds with limited spaces

Single-Cab Truck Sub Boxes

Speaker boxes for single-cab trucks are designed to fit under or behind pickup truck seats. They use low-profile designs that save cabin space while still delivering solid bass performance for larger vehicles.
Best for: Under/behind truck seats

Our Custom-Built Sub Boxes Installation Process

Consultation
& Design

We start by assessing your vehicle, subwoofer type, and music goals. From there, we recommend the perfect custom sub box style to match your preferences and available space.

Custom Box
Fabrication & Selection

We select or build a box tailored to your vehicle. Every enclosure is crafted for optimal bass performance and durability.

Precise
Installation

Our technicians mount the custom-built sub boxes securely, run wiring cleanly through panels, and integrate it seamlessly with your amplifier and audio system.

Testing &
Fine-Tuning

Before you hit the road, we test the subwoofer and box, calibrate gain and EQ settings, and make sure your bass is distortion-free.

Why Our Clients Love Streetfighter Motorsports

They did a great job! They were super friendly and fixed my HIDs quickly. They even replaced my rusted hood pins with some new chrome ones without me asking 😊 definitely recommend going here!

− Erin C

Great service & knowledgeable. Rebecca always takes care of us. Communication is awesome. Have brought multiple vehicles all makes and models. Highly recommend if you are searching for someone that specializes in their craft.

− Nick Rodriguez

Whole team is super nice and they do quality work! Very happy with how everything turned out. Dropped my car off in the morning and it was done that afternoon. These guys don't drag their feet. Highly recommend Streetfighter Motorsports

− Justin Dean

Had the stock woofer taken out and replaced with two new ones in my Durango. Streetfighter did a fantastic job. Finished product is completely hidden and sounds perfect. Couldn’t be happier. You definitely get what you pay for with these guys. Am going to use them again for a few other jobs. Highly recommend.

− Joe Moley

Got me scheduled quickly, identified the cause of the issues:
- Stereo cutting out when turning or driving on a bumpy road. Caused by lose screws on one of the door speakers (my fault haha)
- Subwoofer not putting out any sound. Caused by my 15 year old amp not doing it's job ...

− Aaron Treptow

They had an excellent turn around time for work, helped me install some sound deadening after I got in over my head on it. Price was very reasonable. Owners are nice people, my car is very quiet now on the freeway. I’d definitely come back here for work in the future.

− Carter O'Neill

I had an incredibly horrible experience with Audio Express. Someone referred Rebecca at Streetfighter Motorsports LLC for my Mercedes. She knows her stuff and was so incredibly helpful. I got a new stereo, amplifier and speakers I am thrilled to death with my service and this business. Added a viper car alarm while I was at it! Thank you Streetfighter Motorsports LLC
