DS18 AMPKIT4 4 Gauge Amplifier Kit

The DS18 AMPKIT4 is a complete 4 gauge amplifier installation kit designed for car audio enthusiasts adding a single amplifier to their system. It bundles every wire and connector needed for a clean, professional install in one package. This kit suits DIY installers who want matched components without sourcing parts separately. It is not for builders running multiple amplifiers or systems requiring larger gauge power wire.

Super-Flex-Twist Cables and Included Hardware

The kit supplies 17 feet of 4 gauge red CCA power wire and 3 feet of matching black ground wire, both using Super-Flex-Twist construction for easier routing through tight vehicle cavities. A 100 amp AGU fuse holder with fuse, 6 feet of split loom tubing, and assorted connectors, terminals and wire ties are included. The pre-measured lengths reduce waste but limit placement options for batteries mounted farther than 17 feet from the amplifier.

Upgrades from 8 Gauge Kits and Basic Wiring

This kit replaces 8 gauge wiring kits when amplifier current draw exceeds the capacity of smaller conductors, providing a safer power path for mid-power amplifiers. The included shielded twisted-pair interconnects and dedicated remote turn-on wire eliminate the noise and reliability issues common with improvised signal cables. The jump is worth it when installing a new amplifier that specifies 4 gauge power requirements or when previous installations suffered from voltage drop or alternator whine.

Questions about this item

What current does the 100 Amp fuse in this kit cap the 4 Gauge power wire at?

The included AGU fuse holder contains a 100 Amp fuse, which limits the maximum current draw on the 4 Gauge power wire to 100 Amps.

What physical space does the 204-inch package length require for storage or routing?

The kit ships in a package approximately 204 inches long, so you need at least 17 feet of straight or coiled space to store or route the bundled cables.

How are the Super-Flex-Twist cables installed, and which connection step is most often missed?

Run the 17-foot red power wire to the battery, the 3-foot black ground wire to a clean chassis point, the 17-foot speaker cable and interconnects to the amp, and the remote turn-on lead to the head unit; the step most often missed is securing the AGU fuse holder within 18 inches of the battery terminal.
