Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

The XS Power RK2GA-1 Cable Kit delivers a compact, focused big 3 upgrade solution for single-battery systems that need stronger charging system wiring without a full dual-battery layout. Pre-terminated and matched in gauge throughout, this amp wiring kit companion makes the most critical wiring improvement in car audio simple and approachable.
Upgrade Your Charging System Ground Up
The stock wiring in most vehicles was never designed to support aftermarket amplifiers, and the RK2GA-1 corrects that gap with quality OFC power cable runs sized for real current demands. Replacing undersized factory cables with heavy battery cable conductors lowers resistance, steadies voltage, and gives every component in the system more consistent power — benefits that are audible from the very first listen.
