Dual amplifier kit for Jeep JL and Gladiator JT

The Heise JP-18AMP-2 is a complete installation kit that lets owners of 2018-up Jeep JL and 2020-up Gladiator JT models add a four-channel amplifier, subwoofer and sub amplifier using small form-factor amps. It includes a factory radio T-harness so original speaker wiring remains intact. The package also supplies two black powder-coated under-seat amp racks and all mounting hardware.

Factory-amplified vehicles

This kit is not compatible with vehicles that already have a factory amplifier, so buyers with that configuration cannot use it. It is designed only for aftermarket radio installations and requires small form-factor amplifiers; larger chassis amps will not fit the supplied under-seat racks. No provision is made for retaining any OEM amplified audio system.

4 AWG power and ground

The kit provides cut-to-length braided 4 AWG T-Spec V10 fully tinned marine-grade power and ground cables, which define the maximum current the installation can safely carry. Four-channel RCA, remote and speaker wire plus two-channel RCA, remote and 12 AWG speaker wire are also included. Two MANL T-Spec fuse blocks on a vehicle-specific bracket complete the power distribution.

Questions about this item

Which kit version do I need for a 2020 Gladiator JT?

The single kit listed covers both Jeep JL 2018+ and Gladiator JT 2020+ models.

What does the 4AWG power cable actually deliver in my Jeep?

Marine-grade tinned copper handles the current for a 4-channel amp plus a sub amp without voltage drop.

How does the factory T-harness affect the install?

It plugs into the stock radio connector so you keep the original speaker wires and avoid cutting the harness.
