Car Audio Tools & System Builder
Professional-grade calculators and tools to design, wire, and optimize your car audio system.
Build Your System — Step-by-Step
Plan My System
Pick the right subs, speakers, and amps before you spend a dollar.
Subwoofer Selector
Find the right sub for your goals, vehicle, and budget — no more guessing or buying the wrong size.
Subwoofer Amp Matching
Get the exact power range your subs need. Prevents blown subs from overpowering or weak bass from underpowering.
Speaker & Amp Matching
Match your mids, highs, or components to the right amp channels — so every speaker gets clean, full power.
Design My Install
Size your enclosure and make sure your electrical system won't let you down.
Subwoofer Box Calculator
Get exact enclosure dimensions, port specs, and a cut list you can take straight to the shop. Wrong box = wrong sound.
Electrical Load Calculator
Find out if your alternator and battery can handle your amps before you blow a fuse or kill your battery.
Power Wire Calculator
Get the correct wire gauge for your amp's current draw and run length. Too-thin wire = heat, voltage drop, and fire risk.
Wire & Configure
Get your wiring right the first time — bad wiring is the #1 cause of blown gear.
Subwoofer Wiring Diagrams
See exactly how to wire your subs to hit the right impedance — with visual diagrams for every common config.
Impedance Calculator
Calculate your total load for series, parallel, or mixed wiring. Wrong impedance = clipping, overheating, or damaged gear.
Amp Gain Calculator
Set your gain by the numbers instead of by ear. Protects your subs from clipping and gets the cleanest output.
