Aftermarket amp to factory speakers
Hello guys!
Sorry if I've posted in the wrong section.
So, I installed an aftermarket head-unit, amplifier and subwoofer to my B7 A4 (2005, non-BOSE speakers - only the rear speakers are amplified, along with subwoofer)
My rear speakers do not put out as much sound as the front ones, because of the factory amp I guess. As I already have an aftermarket amp (for my aftermarket subwoofer), with 4 channels, is it possible to wire this AM amplifier to the factory speakers? If yes, how?
Or should I just connect the rear speakers directly to the HU (as the front ones are) ?

I did them.
If anyone wonders. I used speaker wire from aftermarket amp to factory amp's connector. There are three pins on the left side (where the + and - are located, right next to those). From left to right: Top: right speaker + bottom: right speaker - (or left? can't remember), next one is the other speaker and the last is the subwoofer. The speaker wire was red-brown (or yellow?) for + and black-brown for - . Then I set my amp to play both high and low frequencies and turned the bass level all the way down, along with the HPF all the way to the max (so it plays the least amount of low frequencies)
