Amp upgrade: Factory HiFi wiring harness adaptor?
Hello.. I have a 2010 535i with the factory Hifi system in it... the main cabin speakers (front door tweeters and midrange and rear deck speakers) play from the head unit and the under seat subs play from an amp in the boot...
I've tapped into the wires going into the amp to provide line-level signal and turn-on lead to an aftermarket amp and sub in the boot (while still powering the under-seat subs)... but I remember that there was someone on here that was making harnesses that connected without having to cut/tap into any wires... or if there's another harness tap made by someone else that does the same thing does anyone have any info on these? Thx!! |
