Authorized dealer · Car Audio Bargain
Most single-amplifier systems land in the range where 4 AWG power wire is the practical choice: heavy enough for a capable mono sub amp, light enough to route easily through a car. Shop Full Tilt 50-foot OFC power and ground cable in teal, lime green, white, purple and clear, Full Tilt 4 AWG OFC amp kits, 100-foot tinned OFC spools in black and silver, and Sundown Audio and XS Power options.
Orders leave Newton, North Carolina, and shipping is free on orders over $250.
4 AWG sits in the middle of the range. In OFC it comfortably feeds amplifiers drawing up to roughly 100 amps on a short to moderate run, which covers many mono subwoofer amps around 1,000 watts RMS and most 4-channel and 5-channel amps. To check your own system, divide the amplifier's RMS rating by about 13.8 volts and then by its efficiency. A class D amp is often near 80 percent efficient, while class AB designs are lower and draw more current for the same output.
The 4 AWG power wire spools and kits shown here are labeled OFC, which carries current with lower resistance than copper-clad aluminum. That matters at this size because CCA of the same gauge performs closer to a smaller copper wire, and an undersized feed shows up as dimming lights and an amp that cuts into protection. The tinned OFC spools add plating over the copper strands that helps resist corrosion, a plus in humid climates or under-hood routing.
Fuse the cable near the battery with a fuse no larger than the 4 AWG run can carry, using a holder from fuses and fuse holders, then finish each end with matching terminals and lugs and 4 AWG heat shrink. To buy everything at once, the 4 AWG kits in amp wiring kits bundle the core pieces. Not sure of your current draw yet? Pick out your amplifiers first, then return to Cable & Wire for the rest.
