Cable & Wire

Shop power cable, ground cable, speaker wire, RCA cable, and complete amplifier wiring kits for car audio and high-current electrical installs. Cable is available in 1/0 AWG, 2 AWG, 4 AWG, and 8 AWG for runs from the alternator and battery through to amplifiers and distribution.

Undersized cable is one of the most common reasons a charging upgrade underperforms. A 400 amp alternator cannot deliver what the wiring between it and the battery will not carry, and voltage drop across a long thin run shows up as dimming and clipping under load.

Browse Big 3 upgrade kits to re-cable the alternator, chassis ground, and engine ground, or read our Big 3 wiring guide before you order.
