SYSTEM PLANNING

Tell us what you want it to do. We’ll build the system around that.

You do not need to show up with six part numbers and hope they make a system. Tell us what sounds bad now, how loud you want it, how much bass you want, what space has to stay usable and where you want the project to end up. The factory signal, speakers, enclosure, amplifiers, electrical, fabrication and tuning get chosen after the goal is clear.

WHAT DIRECTION ARE WE GOING?

Start with the complaint or the goal—not a random shopping cart.

Better Than FactoryFactory system flat, harsh or missing bass?Fix the weak links with the right speakers, mounting, power and bass without overcomplicating the vehicle.Daily upgrade
Sound QualityWant the music organized up front?Front-stage layout, DSP, amplification and sub integration are built around controlled listening.SQ direction
Loud / Bass / Pro AudioWant more output? Good. Build enough system for it.More cone area, amplifier power, crossover protection, enclosure and electrical support all have to move together.Build it big correctly
Full CustomWant audio, fabrication and Lit FX to look like one project?Packaging, CNC, acrylic, lighting, racks and tuning are designed together from the beginning.Complete project
REAL SYSTEM PLANNING

The photos make more sense when you see the decisions connected behind them.

2022 Jeep Wrangler JL Interstate AGM battery and under-hood power wiringWrangler JLSpeaker tower and bass are only half the picture.This project also included battery and power work, amplifiers, speakers and DSP. The electrical and audio system were planned together.2018 Ford F-150 system correction and DSP retune2018 F-150Frustrated with an install done elsewhere?Speaker choice, amplifier gain structure and the DSP tune all needed correction. Fixing one piece by itself would not have fixed the system.2020 Silverado Bose Mosconi DSP integration2020 SilveradoFactory Bose signal first. New system after that.The OEM source had to be understood before the aftermarket signal path and final tune could be built correctly.2022 GMC Denali enclosure for four 8-inch subwoofers2022 DenaliWant four 8s under the seat? The space gets a vote.The truck’s usable volume and driver geometry had to be worked out before the final bass layout made sense.
PLAN IN THE RIGHT ORDER

Goal first. Vehicle second. Hardware after that.

  1. 01What do you want different?

    Listening goal, vehicle use, budget, space and future plans.

  2. 02What does the vehicle give us?

    Factory EQ and routing, speaker locations, enclosure space and integration requirements set the system layout.

  3. 03Match the connected parts.

    Speakers, bass, amplifier channels, impedance, power, wiring, battery and charging support are not separate decisions.

  4. 04Install it, verify it and tune the finished system.

    Fabrication, polarity, gain, crossovers, DSP routing, timing, EQ and final listening finish the plan.

START THE PLAN

Tell us the vehicle and the result. We can figure out the hardware from there.

Send the year, make, model, trim, factory package if known, current equipment, useful photos, goals, budget, space requirements and future plans.
