Pro Amplifier Wiring Kit 4000W

The WUQ EA-PROK4 is a complete 4-gauge amplifier wiring kit built for car-audio installers who need a single package to power and connect a high-output amplifier. It delivers 100 percent tinned oxygen-free copper conductors throughout for low resistance and corrosion resistance.

Brass ANL fuse holder and quad connectors

A solid brass ANL fuse holder protects the vehicle electrical system while quad brass connectors, 4GA ring copper terminals and ferrules create secure, professional terminations. The kit also supplies heat-shrink tubes, butt connectors, spade terminals and zip ties for a clean, finished installation.

4000W maximum power rating

The kit is rated for 4000W max power, making it suitable for amplifiers that demand high current on 4-gauge cable. Systems requiring more current capacity or a different cable gauge will need a separate wiring solution.

Questions about this item

What current load does the 4-gauge oxygen-free copper power cable support in practice?

The kit includes a solid brass ANL fuse holder rated for 4000 W maximum power, which sets the practical limit for the 4-gauge power and ground cables.

What length of 4-gauge power cable is supplied for routing to the battery?

Seventeen feet of 4-gauge tinned copper power cable and three feet of matching ground cable are included for the battery-to-amplifier run.

How do you properly crimp the 4-gauge ring terminals without damaging the tinned copper strands?

Strip the insulation cleanly, insert all strands fully into the barrel, and use a proper 4-gauge crimp tool — pliers or a hammer crimp will leave loose strands and high resistance.
