Start from the source. Your head unit sends the audio signal, so let's make sure it sends a clean one.

Start with what you want to hear.
You don't need to know the equipment yet. Pick the result that sounds closest. We can sort out the parts after that.
Blown speaker? Or just know the factory setup should sound better? I'll replace or upgrade the speakers in the locations your car already has.
Choose this directionThat's why I'm here. From punchy bass to "disturbing the peace," let's bring the bass.
Choose this directionWhether you chase every detail or you're just tired of the car missing notes your headphones hit, I'll build the system so every part works together.
Choose this directionNot for the faint of heart. Built to disturb the peace or compete. Let's get loud.

Tuned, not guessed.
When car audio is rushed, you hear it. Distortion. Noise. Gear that never lives up to its potential.
When every part is installed and tuned to work together, it hits different. That's what I chase for every vehicle I touch.
Why I do it this wayMeasured tuning
Every gain is set with an oscilloscope instead of a guess.
Wiring that lasts
Connections and runs are treated like they need to outlive the car.
I come to you
The tools, parts, and attention to detail come to your driveway.
Your sound first
The build follows what you want, not whatever box needs to be sold.
Brands I like to work with
Final gear depends on your vehicle, goal, and budget.

How it works
No mystery under the dash.
You tell me the sound you want. I look at what the vehicle needs. Then we plan the system instead of stacking random parts.
- 01Tell me what you want
Cleaner sound, more bass, a full build, or a problem you need traced.
- 02I look at the vehicle
Existing gear, wiring, space, electrical needs, and anything already modified.
- 03We plan the system
We match the system to the goal, the vehicle, and what is worth changing.
- 04I install and tune
I route and protect the wiring, measure the tune, and show you what was done.
Current work
Small details. Real signal.
The photo library is still growing. The site will use what is real instead of pretending quantity is proof.
Low end
Subwoofer installs
Punch, depth, enclosure fit, power, and electrical reality all belong in the same conversation.

Better drivers only matter when the install, fitment, wiring, and source are handled together.

Ready when you are
Tell me what you want your car to do.
You don't need a parts list. Tell me about the vehicle, the problem, and the sound you're after.
Plan your systemBefore we start
Straight answers.
Where do you work?
Grung Audio is a mobile service based in the Bitterroot Valley, MT. I bring the tools, parts, and installation to you. We confirm the job and appointment time before scheduling.
Do I need to know what gear I want?
No. Tell me what sounds wrong now and what you want to hear. I'll help narrow the system down from there.
Can you look at an existing install?
Yes. Tell me what the system is doing and anything you know about the existing equipment or wiring. I'll be straight about what's worth keeping.
Is the date I request guaranteed?
No. The form starts the conversation. I confirm the job, location, and actual appointment time with you before anything is scheduled.
