In addition to the W206 forum, I am also at home in the mini forum on Motor-Talk. 🙂 In a few weeks, my better half will get their Cooper Clubman from 2020. Since the car only has the standard sound system, something stronger has to be done. I have planned the system as far as possible, but I hope to get some tips about the power sources. In addition to the usual safety box in the engine compartment, I still have the one behind the glove compartment. Are there any other boxes or power distributors where I can tap the current for the amplifier (desirable value in the trunk)? _____ In case you are interested in what I want to install, here is a brief description of my project: Centrally the new sound system is to be controlled by a Match Up 8 DSP. The signals for front/rear channels are picked up directly on the radio. This is done by a quadlock on ISO T adapter and the ISO connection cable of the verse In addition to new Koax speakers in the front doors, the car gets new 2-Ohm underseat woofers, which are actively driven. Accordingly, they are separated from the original wire harness and equipped with a sparate wiring from the amplifier. The old cables are still used to fire the door speakers, since they switch in parallel in the origin. Matching sockets for bridge are already available. Thus, the system is operated over 6 channels. We’re in Cologne!
