System paths

From daily-driver fix to reference-level sound.

We help you prioritize the upgrades that create the biggest improvement for your budget, in stages if you want.

Start here

Factory system improvement

Targeted speaker, subwoofer or integration upgrades that keep your factory radio and controls.

  • Door and component speakers
  • Powered or loaded subwoofer
  • Factory integration with AudioControl
Most builds

Performance system

Matched speakers, amplification, subwoofer, sound treatment and tuning.

  • Kenwood eXcelon head unit with CarPlay
  • Amplifiers and MESA Wire wiring
  • JL Audio Stealthbox or custom enclosure
No limits

Custom high-end system

Purpose-built fabrication, advanced DSP control and detailed acoustic tuning.

  • Custom trunk, door and A-pillar fabrication
  • DSP processors, time alignment, EQ
  • Show-level finishing and lighting

Installation standard

Designed to perform and stay serviceable.

Clean wiring, correct fusing, secure mounting, ventilation and thoughtful integration matter as much as the equipment.

Evaluate

Listen to the factory system and define your priorities.

Design

Select compatible components and an upgrade path.

Install

Clean, protected, vehicle-conscious installation.

Tune

Verify operation and tune the system for the cabin.

Build your system

Start with what bothers you. We tell you the first fix.

Most systems should be built in stages. Tap the thing you notice most and see where the money goes first.

First upgrade

Add a subwoofer and a mono amp

Factory speakers are not built to move air below about 80 Hz. A single 10 or 12 inch sub with its own amplifier fills in the bottom end without touching the rest of the system. Keep the factory radio.

The GTO build, spot by spot

What a custom trunk looks like when nothing is off the shelf.

This Pontiac GTO came in for a sound system and left with a trunk built around it. Tap the dots. Every panel, the lighting, the enclosure and the wiring were done in our bay on Hammer Lane.

Pontiac GTO trunk build: JL Audio amplifier on a custom back panel with purple-lit angular cutouts, subwoofer flush in the floor, wrapped side panels
1 of 5 · Amplifier

JL Audio amp, mounted where it can breathe

Centered on the back panel with open air on every side and the terminals reachable. Heat is what kills amplifiers. An amp buried behind a sealed panel runs hot and dies early; this one is on display and cool.

Before any car leaves
  • Tested with you in the seat
  • Factory functions kept
  • Power and ground metered
  • No rattles at full volume
  • Interior back without marks
  • Photos for your records
