Description
PAC APH-CH01 — Chrysler / Dodge / Jeep / RAM Factory-Amplified Speaker Connection Harness
On the supported Chrysler-family system, AmpPRO gives us the clean signal and APH-CH01 gives the new amplifier a clean way back into the factory speaker wiring. It connects at the compatible factory-amplifier location so we can reuse the vehicle’s original speaker circuits instead of cutting the harness or running new wire through every door.
CH01 and CH03 are different amplifier-connector families. A Jeep, RAM or Dodge badge does not decide the part. The actual factory amplifier, trim and audio package decide the harness; use CH01 only where that connector is specified. Similar vehicles can land on CH03 instead.
PAC’s APH layout also lets the system stay flexible. Speaker circuits being moved to the aftermarket amplifier can be routed through the long leads, while selected channels can remain on the factory amplifier where the application and system design allow it. The factory amp stays connected when AmpPRO needs it for vehicle-data communication.
Published details: 18-inch harness; used with applicable PAC AmpPRO systems including AP4-CH21 and AP4-CH41 where specified. PAC recommends tone-testing the speaker circuits before final connection because OEM channel assignments can change by year and trim.
Harness only. AmpPRO interface, DSP and aftermarket amplifier are sold separately.

Where this fits in the build
This is a system-control or DSP component. The correct choice depends on the signal path, channel count, routing, retained features and the rest of the amplifier and speaker plan.
Plan aroundVerify the source signal and vehicle architecture first.
Match itPlan inputs, outputs, summing, routing and gain structure as one signal path.
Finish itTune after installation, polarity, crossover capability and levels are correct.
