What Sets Us Apart

01 / 04

IASCA Champion, SPL Record Holder

Our president built competition systems that set SPL records and won IASCA championships. That acoustic knowledge is in every install — from a head unit swap to a full custom build.

02 / 04

OEM Integration Done Right

Factory steering wheel controls, backup cameras, factory amplifier bypass, and CANBUS interfaces — handled correctly so nothing breaks six months later.

03 / 04

Wiring That Lasts

Proper gauge wire, inline fusing within 18 inches of the battery, heat-shrink connections, and clean routing through factory channels. No wire nuts, no shortcuts, no fire hazards.

04 / 04

Tuned for Your Car

We set gains, crossover points, and time alignment for your specific vehicle interior — not a generic flat EQ. The difference between a good install and a great one is the tuning.

Frequently Asked Questions

How much does car audio installation cost in Miami?

Cost depends on the scope — head unit swaps, subwoofer and amplifier installs, and full custom builds are all different jobs with different requirements. We provide itemized quotes before any work begins — no surprises at pickup. Contact us to get a personalized estimate.

How long does car audio installation take?

Head unit swaps: 2–3 hours. Subwoofer + amp installs: 3–5 hours. Full custom builds: 1–3 days depending on scope. Most standard installs are same-day if you drop off by 10am.

Do you install equipment I bring, or only equipment you sell?

Both. We install customer-supplied equipment all the time. The only condition: we won't install equipment that's clearly damaged or counterfeit, and we'll let you know if something you've brought isn't compatible with your vehicle before we start.

Will a new head unit work with my factory steering wheel controls?

Yes — for virtually every vehicle made in the last 15 years. We use OEM interface adapters (iDatalink, PAC, Metra) that retain steering wheel audio controls, factory amplifier signals, and backup camera outputs.

Do you do competition car audio builds?

Yes — competition SPL and SQ builds are part of our roots. Our president is an IASCA champion and SPL record holder. If you're building for IASCA, dB Drag Racing, or World Finals, we know the rulebooks and build requirements.
