Thread: Multi-In, Multi-Out Switch Needed

He's not doing this to a headunit as its an switch selector for inputs to an amp.

The pioneer internal amp is able to bridge the rear two channels to power a low power 2ohm sub. Means that you can't tie the ground outputs together.

I know what he is doing, it might not be suitable to tie the grounds together anyway, better to be on the safe side, right?

Is this what I want?

Rob, I'm really going back to basics with this, do you know of any other sites with Aux in hacks like your that describe it in anymore details?

I'm absolutley useless at reading plans unless they are real Schematics for dummies type ones with every part described in detail, with names as well as symbol and part number.

Nope, sorry, I don't know of any other sites with headunit mods. Every headunit is different.

Damn. OK. As a lot of cheaper ones effectively use a budget CD drive, I wonder if you could hack a relay into the audio outs of the cd drive?

Yep, you can do that. That's basically what I did with mine, except that I tapped into the fm radio lines before the audio processor (so volume, balance and faders still work).
