I bought a pair of audiopipe subs for my sail panels which im pretty sure are supposed to be a direct replacement. Whoever had my car before had already unplugged the stock speakers because they were blown so I just need a little bass. There are 4 wires. Two sets of red/black and red. Either way that i connect the wires the sub is getting practically no power. It barely moves....anyone know what im doing wrong?

 

Check the wiring at the stock harness, here's what the pos and neg should be (from the Monsoon FAQ):
TAN - right rear subwoofer negative output
RED - right rear subwoofer positive output
LIGHT BLUE w/BLACK - right rear subwoofer speaker negative output
DARK GREEN - right rear subwoofer speaker positive output
It sounds as if one of the wires is not matched up correctly.

 

HINT: You'll have to go a little farther back in the harness to find those wire colors. The speakers have pigtails of just red and black wires that connect to the wiring harness where you'll find the colors listed above.
