SOURCE: Keep poping the 40 amp fuse on the amps itself when the volume is up at all it seems
Your units drawing too much current. it could be a wireing problem, a speaker problem, or the amp has a problem. the correct way to troubleshoot this would first do or have the amp bench tested. Or you can remove all the speakers and wires and turn up the amp. If the fuse still pops,have the amp serviced. Good Luck

I would either try a bigger fuse, if possible, or turn the power output dial on the back of your amp down. This can be done with jus a simple flathead screwdriver. I suggestion would be to go out and buy a power monitoring cap. Wal-mart, or Tweeter usually distributes them. It'll have a LED reading on the top, with two wire hook-ups either on the bottom or the top for positive and negative, place this in between your amp and your subs in the wiring set-up.

What sort of problem are you having with it?
SOURCE: Blowing of fuses
The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.
