Hi - sorry, this is probably a basic question but I haven't been able to find an answer after an hour of searching around the net. I'm hooking a Fusion CP-AS1080 active sub up to a Clarion headunit (CX501a), but cant seem to get sound through it. Power coming through the main line and remote, fuses are good, ground is directly into the chassis. When I unplug and replug the RCAs I get a burst of vibration through the sub, but nothing else comes through.
Any ideas?
