Features
Overview: This vehicle specific harness simplifies adding the Focal Impulse 4.320 amplifier to a compatible vehicle. The ISO extension cable (item number 091IMPEXT1, sold separately) must also be added to connect the amp. This adapter supplies the amp with a speaker level signal input, power, and ground, and connects the amp's output to the factory speaker wiring. (Power and ground for the amp are connected using the attached crimp connectors.) Please enter your vehicle information to confirm compatibility.
