I have an MTX 6304 four channel powering my comps and rear speakers. I want to give more power to my focals with an mtx 8302 to match the other mtx amp. Then possibly run a sub off a bridged channel on the 6304. A sub like a JLW3, Focal 27k, something low power because I don't like too much bass. What am I going to have to upgrade in way of wiring, I was thinking a new 120 amp fuse to replace my 60 amp with my 4 gauge wiring kit. What else do I need? Can my car handle it? I have no dimming whatsoever with the highbeams and the AC on while driving with my music on right now.

I would say you would be ok with both those amps. I doubt they would both draw over that much.

Also be careful. Most amps when bridged can only handle 4 ohm loads.

Then again you could just bridge the 6304 and drive just the fronts, rears off deck power, and get a monoblock sub amp. Thats similar to how I have mine setup.

I think 120 amps is a bit much...i'm sure mohawk will correct me, but I ran a JL 500/1 and a PC250 off one 60 amp fuse for a year or so....and it never blew, even when I cranked it all the way up.
