Amplifier with/ or without Subwoofer Installation Guide ’18- ’23 Jeep JL Wrangler/ ’20- ’23 Jeep JT Gladiator
Installation video by Trail Seven, to be used with the written instructions below:
1. Remove Radio-
If connecting to a factory radio, see the PAC module installation instructions covered in step 2. If you’re connecting to an aftermarket radio, you’ll need to expose the RCA’s on the back of the radio or connect the RCA harness to the radio to connect the amplifier to. NOTE: if you’re connecting to an aftermarket radio, and your jeep is non-factory amplified, your 9-wire harness will not have plug and play connectors pre-terminated. You will connect the blue amp on wire (which we’ve connected a pink bullet connector) to the amp on wire at the back of your radio. You will also need to connect the 8 speaker wires which will match up color to color. Be sure to disconnect the speaker wire connector from the head unit so you don’t send the amplifier signal into the head unit. The 9-wire will connect to the wires which will face into the jeep harness which directs to the speakers. We have included 8 pink male and 8 pink female connectors for you to strip and connect the wires with.
3. 4 or 5 Channel Amplifier-
We have fully prepped the amp wires for an easy plug and play installation. All power, ground, remote, and speaker wires have been pre-terminated with fork connectors to easily attach to the appropriate ports on the amplifier. NOTE: proper speaker dedication is referred to as AMP1, AMP2, or SUB on some amplifiers. Amp1 is in reference to the front speakers, Amp2 is in reference to the rear speakers, and Sub is of course the subwoofer.
