The nerdling 7 years ago on Introduction. It is important to get the power from the battery and not the fuse box. That could mean your amp cannot handle the sub. What you want is the RMS of both the subwoofer speaker and the amplifier to be as close as possible. If your amplifier accepts line level signals only, you will need to cut the wires coming from the back of your head unit and splice them to the corresponding wires on a line-out converter.
