About the Focal IW-IMP-EXT150
From our tech experts at CEN
The Focal Inside IMP Extension Cable I/O 150 (IW-IMP-EXT150) is a 1.5 m plug-and-play input/output extension cable made exclusively for the Focal Impulse 4.320 4-channel digital amplifier. It extends the wiring loom between the amplifier and its mounting point, giving greater flexibility over placement. Twisted cable construction and a cut-resistant protective shield reduce interference and protect the loom.
Who it suits
This cable is for anyone installing the Focal Impulse 4.320 where the standard loom does not reach. It suits both professional fitters and careful DIY installers who need a clean, solder-free solution.
Our tech experts advise
This cable works only with the Focal Impulse 4.320 and is not compatible with other amplifiers. The double In/Out connector carries both the input signal from the head unit and the amplified output back to the speakers through one loom. Installation pricing varies by vehicle; see our Nottingham fitting page for details.
