About the XS Power BIG3XS
The one-step "Big 3" upgrade kit
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 350 amps, this "Big Three" grounding kit will boost your electrical system's performance.
XS Power's Big3XS kit includes heavy-duty 1/0-gauge oxygen-free copper 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.

Customer Q&A
Q
Do I replace the wires in the car with this or should leave them connected and just connect these on top? I figure this way there will be an extra connection on each line so maybe better?
A
Leave the original cables connected.
