45A fuse is good for that amplifier the way we're about to wire it.

you need to go to rockfordfosgate.com and fine the manual for that model, or anything similar to it that's 4 channels.
find out how to set the amp to bridged mode.
wire the amp properly using a wiring kit (knukonceptz.com has a 4ga kit for $30) so everything gets proper current.
that being done, you'll bridge the amp to run in 2 channel mode, and put one of the 4 ohm subs on each of the two bridged channels.
this will give you a clean 200 watts per sub, which should really make those blitz subs you got (yeah, no names, but hey if they work....) hammer.

what sort of automotive work do you do?
