Who We Are

We Don't Just Sell Gear.
We Build Experiences.

Amp Revamp started with a simple belief: your car's sound system should match the effort you put into everything else. Located right here in Wahiawa, we've spent years helping drivers, audio enthusiasts, and everyday commuters turn their vehicles into mobile listening rooms.

Whether you're looking for a clean factory upgrade or a full-blown competition-level build, we treat every project like it's our own ride. That's the standard — and the reason our customers keep coming back.

What We Do

Services Built Around
How You Listen

Every project starts with a conversation. Tell us what you hear — or what you wish you heard — and we'll make it real.

Custom Amplifier Builds

Bespoke amplifiers designed for your exact power needs and sound profile. From Class D efficiency to Class AB warmth — we build the heart of your system.

Complete Car Audio Installation

Head units, speakers, subwoofers, and everything between — professionally wired, tuned, and tested. We make it look clean and sound filthy.

Subwoofer & Enclosure Design

Custom-fabricated enclosures that match your vehicle's space and your bass preferences. Sealed for precision, ported for pressure — you choose.

Signal Processing & Tuning

Time-alignment, crossovers, and EQ — the invisible art that separates good sound from great sound. We dial it in so every seat sounds perfect.

Sound Deadening & Acoustics

Reduce road noise and resonance with professional-grade damping materials. A quieter cabin makes every note hit harder — and your music sounds richer.

Repair & Diagnostics

Blown amp? Distortion in the bass? We diagnose and repair all major car audio brands. Honest assessments, fair pricing, no guesswork.

What People Say

Our Customers Drive
The Proof Home

"I brought in my setup thinking it was fine. They rebuilt the entire signal chain and now I'm hearing details in songs I've had for years. Absolute game-changer."

Marcus T.

Wahiawa, HI

"They built a custom enclosure that fits perfectly in my trunk — no wasted space, no compromises. The bass is tight, punchy, and doesn't rattle a single panel. Impeccable work."

Jenny L.

Pearl City, HI

"Honest, knowledgeable, and they actually care about the result. I've taken three cars here over the years. Each one sounds better than the last — and I always leave smiling."
