Fuse keeps blowing, Why?

I have a 2002 Ranger Edge pickup.  I have an Alpine CDA7875 Cd player 60wX4 channels.  I have a Profile Califonia 600sx amp bridged with 2 MTX Thunder 6000 10" subwoofers(4Ohm)  The RMS bridged is 450X1 Peak is 600X2, so I am not sure what Peak is bridged.  I have, unfortunatly a 10 guage power cable running approx. 18 ft.  I keep blowing the 30AMP fuse on the power cable when I put the volume past 10, it goes to 35, the gain and bass boost are turned down and the preamp control on the deck is midway.(Bass is at 0)

I am assuming that the problem is the cable size and fuse on that cable (power cable).  Bu ti recently had the same exact setup in a 93 explorer and had no problems like this.  So I am wondering if it would be safe as far as the car alternator and battery are concerened, to put a thick guage power cable and bigger fuse in, and what size fuse I should use?

Or should I just tone everything down and live with it?

thanks for your help

Change the wire size running from the battery to the amp. You should be using at least 8 guage instead of 10.  That's probably why you keep blowing your fuse. I'm assuming that the Ranger has a V6 engine, if that the case then with the V8 of an explorer you probably wouldn't have had this problem because the alternator of the V8 is produce more power to compensate for the bigger engine  than that of a V6.

Also I would think about changing the fuse size from 35 to at least 50, just to be on the safe side.

Don't - I repeat - DON"T use a greater than 30 amps on that 10 gauge wire. DO check that the wire is not shorting at all to ground (where it runs through firewall or next to sharp edges). To me, it seems that you are pulling too much through that wire. For an amp that size, I would run 8 gauge with a 50 amp fuse. Or, if you ever plan on upgrading (or just to be on the safe side) use a 7 ga. w/ a 60 or a 6 ga. w/ an 80 amp fuse. That should solve your problem, and should be the first thing to check/replace.
