Audio woes

[midlandtech]

Hey guys and gals I am having trouble getting my audio signal to the new amp. I tapped speaker levels at the factory amp yellow and black twisted with brown orange and blue and black twisted with brown and orange then am using the high level inputs on the amp and am getting no signal what am I Doug wrong? I am thinking about getting a LOC and trying that next but I'm getting to the end of my rope

Is that on the outgoing side of the incoming side of the factory amp? I think you want to be on the incoming, non-boosted side of the signal.

Yup those exact wires

So as Static said, you are taking the signal before the stock amp.

Could the amp you purchased have a beef with line input signal from our head units?

[midlandtech]

It might I am doing high level inputs an am thinking of going and buying a heavy duty loc to see if that works... It's a European brand amp was hoping that if I went that route I would negate any conflicts

Whats a LOC?

[midlandtech]

Line out converter... takes speaker level and converts to a RCA level its also called a line level converter

I think you will need a line out converter. The BMW head unit is not putting out a true speaker level out put. I saw a post on e46fanatics where a guy claimed you did not need one, but all the other installs I have seen use them.
