The one-step "Big 3" upgrade kit
If your aftermarket audio system is putting a strain on the rest of your car's electronics, you might want to upgrade your factory wiring. Rated to 250 amps, this "Big Three" grounding kit will boost your electrical system's performance.
XS Power's Big3XP kit includes heavy-duty 1/0-gauge copper-clad aluminum cables that replace (or augment) your vehicle's battery ground-to-chassis wire, the chassis-to-engine block wire, and the wire connecting the alternator's positive output to the battery's positive terminal.
Another bonus is that the 8.5 mm ring terminals are already crimped to the wires, so you won't have to replace the stock grounds unless you want to improve them or double up. Extra ring connectors are included, so you'll be able to trim the wires to length and replace the terminals if needed.
This Big3XP kit includes:
1 6-foot XPFLEX 1/0-gauge power cable
2 4-foot XPFLEX 1/0-gauge ground cables
8 XS Power heat shrink tubes
8 1/0-gauge crimp terminals (already crimped on the wires)
10 wire clamps
10 zip ties
Warranty: 1 year
