Use an 18mm socket to remove the four seat bolts.
-
Use a T45 Torx to remove the seatbelt bolt (if needed).
-
Tilt or fully remove the seat for better access to the amp location.
Step 2: Route Power and Ground Wires
-
Power Wire:
-
Route the 4-gauge power wire from the battery through the driver-side firewall (use the factory grommet or drill a small hole if necessary).
-
Run the power wire along the driver-side trim panels to the amplifier under the seat.
-
-
Ground Wire:
- The 5-Channel Amp Ground: Use the factory ground point under the driver seat (near the transmission tunnel).
-
Ensure a solid connection by removing any paint at the contact point.
-
Remote Turn-On Wire:
-
Route the blue remote wire from the PAC module (if using a factory radio) or from the remote wire of an aftermarket radio.

Step 3: Remove Radio & Access Signal Wiring
Factory Radio Installation (Using PAC Module)
If connecting to the factory radio, install the PAC AP4-CH41( or PAC AP4-CH42) module behind the glove box. Use the provided T-harness to connect the PAC module to the radio harness. If your Jeep isn’t factory amplified, make sure DIP switch #4 is DOWN (On Position) on the PAC module.
- Connecting the 9-wire harness:
- Connect the "bare-ends" or Ferrules to the Amp to the corresponding wires and channels
- Connect the PAC proprietary plug into the T harness of the PAC AP4-CH41 that located behind the head unit.
- Connecting the Bypass harness:
- Connect the "bare-ends" or Ferrules to the Amp to the corresponding wires and channels
- Unplug the harness plugs from your OEM amplifier, located behind the OBD2 port under the steering wheel, and connect the matching plugs from the Bypass harness to the plugs you removed from the Amplifier (there is one plug you will leave in the amplifier, due to canbus validation for the Jeep.
- Connect the blue remote turn-on wire from the PAC module to the blue amp remote wire (pre-terminated with a bullet connector).
-
Run RCA cables from the PAC module to both amplifiers:
-
RCA's from PAC → routed to the 5-channel amp under the driver seat.
-
Amplifier Speaker Wires:
-
Front speakers → Channels 1 & 2
-
Rear speakers → Channels 3 & 4
