at a loss with my new '10 galant
I installed my stereo just fine in my old car ('03 galant), but something just isn't right and I don't know why.
I know I have the power wire secure and fused correctly. I have tried two grounding locations with no problem in either spot.
I have a jbl 300.1 using line level inputs just like in the old car.
I can get signal to the amp, as the lights light up correctly.
But the sub is barely letting any sound out (obviously just carrying the signal from the spliced rear speaker wires)
I thought at first that the fact I have the rear speakers spliced was robbing the sub of needed signal, so I completely cut the rear speakers out and no change.
The only other thing that happens every time I wire up the sub, my anti-lock and TCL comes on.
Thoughts?
I got the wire colors from two different sources (which agree).
I'm about to give up and pay somebody to install it, but I really don't want to.
