DVC Subs - stupid and confused

So the amp doesn't work but the rest of the system continues to function?  and what model subs are they?

BTW it's a 15 amp fuse, not a 1.5

If you're gonna be using the high-level inputs to send the signal to the amp, you wanna make sure that RCAs are not also connected.  Never use both sources at the same time.  Maybe that's what your problem is?

Also, I'm almost positive that you leave the switch on "stereo" as it appears to be an input select switch.  It says MONO (L ch) and I took this to mean the input.  It's gonna automatically sum the left and right when you bridge the amp anyways.  Others may want to verify this, just check out this pic.

Even if that part is wrong, which I highly doubt, that still shouldn't be causing it to blow a fuse.  You can always try switching over to mono just for the hell of it.
