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.

Q
Can this harness be used on a 2019 VW GTI as a splicer to get signals to hook up a line out converter for an amp to run a subwoofer?

Greetings Ryan. Thank you for your question. This can, however by design it is made for the Focal Impulse amplifier to be a direct plug in. What you would need to do is cut off two plugs and hardwire, or tap in rather than cut off.

Greetings Mike, and thank you for your question. We are not showing this harness fitting a number of Volkswagen vehicles from 2020-2023. The best answer you can get would be direct from Focal at this point. Their number is 888-340-4403.
