Dual-Amp Kit for Jeep JL and JT

This vehicle-specific kit provides all wiring and hardware to install two aftermarket amplifiers and a subwoofer in 2018-Up Wrangler JL and 2020-Up Gladiator JT models. It includes cut-to-length 4AWG marine-grade power and ground cables, 4-channel and 2-channel RCA sets with remote wire, speaker wire, a fuse holder bracket with two MANL T-Spec® fuse blocks, two under-seat amp racks, and a factory radio T-harness. A detailed instruction book guides the installation.

Buyers adding a 4-channel amp, sub amp and subwoofer

The kit suits owners who want a complete, cut-to-length wiring solution for a dual-amplifier system while retaining factory speaker wiring via the included T-harness. Installers who only need a single amplifier or who prefer to assemble their own cable lengths and fuse distribution will not use the extra channels, racks and hardware supplied here.

Two under-seat amp racks included

The kit supplies two black powder-coated racks designed to mount amplifiers beneath the front seats of the compatible Jeep models. This fixed mounting approach determines where the amplifiers can be placed; builders who need a different amp location or a custom enclosure must source alternative mounting hardware separately.

Questions about this item

How do I route the 4AWG marine-grade power cable from the battery to the under-seat amp racks in a JL Wrangler?

Use the supplied vehicle-specific fuse-holder bracket with its two MANL T-Spec® fuse blocks as the distribution point near the battery, then run the cut-to-length 4AWG V10 cable under the carpet and through the factory grommets to the black powder-coated amp racks mounted beneath the front seats.

When will the MANL T-Spec® fuse blocks need inspection or replacement?

Inspect the two MANL T-Spec® fuse blocks during any major service or after deep-water crossings; replace a block only if its housing shows heat damage, corrosion, or a fuse has blown and the block terminals are pitted.

What is the first limitation I will hit when running both amplifiers hard on long trails?

The 4AWG power and ground cables set the current ceiling; sustained high output from the 4-channel amp plus the sub amp will eventually hit the ampacity of that 4AWG run before any other kit component becomes a bottleneck.
