re: I need some help OT (car audio related)

With the line level converter (hi lo), I took out the rear speaker. I then cut the connector off and put spade connectors on it and ran speaker wire from the circuit supplying the rear speaker to the line converter. I then ran speaker wire from the converter back to the door speaker and it doesn't work. I have not hooked up the sub yet, just making sure I can get the converter (checking to make sure all the door speakers are still working, only changed one) to work. Well there is nothing but like one front speaker working.

The converter has inputs for all four speaker front and rear. The instructions say put it behind the factory unit. Two different sets of instructions, one with a harness and one with just the speaker wires coming out the back of the head unit. I thought I could just convert the signal of one of the speakers in line and run it to an amp?

Sense I am only converting the signal for a 2 channel amp for one subwoofer and having all the door speakers work off factory head.

Am I doing it wrong? I am an electrician, but I have never done car audio and only work dc on some instrumentation and it's usually miliamps. From what I think I know, what I did should work. I should be able to tap the speaker wire into the converter and run speaker wire back to the speaker. All I need is one signal for the amp right?

Or do I have to do both sides? Either two in the front or two in the back?

Fffuuuccckkkkk
