Smaller amplifiers do not need the bulk of 4 AWG or 1/0, and 8 AWG power wire is easier to route behind trim and under carpet. Choose Full Tilt 50-foot OFC power and ground cable in teal, lime green, white, purple, clear and red, Full Tilt 8 AWG OFC amp kits, and 250-foot tinned OFC spools in black and silver, with Sundown Audio and XS Power options too.
Add matching lugs and heat shrink to the same order.
8 AWG is meant for modest loads. In OFC on a short run it is generally comfortable with amplifiers drawing up to around 40 to 50 amps, which covers compact 4-channel amps, small mono amps for a single subwoofer, and amps added to a factory system. Estimate draw by dividing the amp's total RMS power by roughly 13.8 volts and its efficiency, or look at the amplifier's fuse rating: an amp fused at 40A or below is a reasonable match for 8 AWG on a short run.
In any of those cases, move up to 4 AWG or larger.
The 250-foot tinned OFC spools make sense for installers or anyone wiring several vehicles, and the tin plating helps keep exposed strands from corroding. Full Tilt's 50-foot spools hold enough 8 AWG power wire for a typical power and ground run, with color choices to match your build. Full Tilt 8 AWG OFC amp kits gather the main pieces in one order; check each listing for contents. Whatever you choose, favor OFC over copper-clad aluminum, since CCA has noticeably more resistance and leaves little margin on a gauge that is already small.
Fuse 8 AWG close to the battery with a fuse rated no higher than the wire can carry. The ANL fuses in fuses and fuse holders are aimed at bigger feeds, so confirm any fuse you choose suits 8 AWG. Crimp 8 AWG terminals and lugs, seal them with 8 AWG heat shrink, and run signal with RCAs. Browse the parent Cable & Wire category for everything else.
