Thread: Balance/Fader Knob + Modern Head Unit

Started 3 weeks, 1 day ago by putin
My dashboard balance knob ( maybe I should say dial ) was disconnected when a new head unit was fitted. I'm mucking around with the wiring at the moment and am wondering if I can find a use for it. Looking at the old wires, it seems to be only 2 channel/stereo, with the original 4 speaker setup sending the same signal to the front and rear speakers. I'm thinking of wiring it to ...

Yeah I get that, no way I can put all 4 channels through it. By the look of it it has 2 earth connections and 4 signals grouped into two sections of (FR, Earth, FL) and (RL, Earth, RR).

You only need a decent pair of front speakers. In my corsa i have it all faded to the front anyway.

Hmmm.. that volume control bodge that Deziac linked to looks neat, gives me an idea. There's a steering wheel control unit for my stereo going cheap on ebay at the moment, think I'll grab it and try hacking something similar up. Thanks guys, I'll post picks if I get anything working.
