The BMW 2.1 IMP HARNESS connection cables are dedicated to the connection of BMW speakers and the IMPULSE 4.320 four-channel digital amplifier. These four-meter-long cables amplify the front channels of a vehicle on two channels, and amplify the two BMW subwoofers on two other amplifier channels. Connections are simple; no soldering is required.

The Focal Inside IW IMP 2.1 car radio adapter cable is designed for the IMPULSE 4.320 four-channel digital amplifier. Without modifying the original wiring, it allows easy connection of the two-channel front amplifier and a PSB 200 subwoofer (two bridged channels). Designed for all types of vehicle, this one-meter-long cable makes Plug & Play installation quick and easy. Connection to the extension cable is via ISO connectors; no soldering is required.

The Focal Inside IW IMP 2.2 car radio adapter cable is designed for the IMPULSE 4.320 four-channel digital amplifier. Without modifying the original wiring, it allows easy connection of the amplifier to two front channels and two ISUB TWIN subwoofers (two bridged channels). Designed for all types of vehicle, this one-meter-long cable makes Plug & Play installation quick and easy. Connection to the extension cable is via ISO connectors; no soldering is required.

Compatible with the IMPULSE 4.320 four-channel digital amplifier, IMP EXTENSION I/O 150 extension cables with Plug & Play connections offer total freedom of installation, as they can link each amplifier channel to any of the loudspeakers. At 1.5 meters long, they are also twisted for effective interference elimination. With these cables, you benefit from an input/output extension: "input" to send the audio signal from the head unit to the amplifier, and "output" to transmit the output signal from the amplifier to the original audio system.
