im setting up my subs and my amp. they push 600 watts rms and im running 4 gauge power and ground wire. the amp kit came with the fuse and fuse holder and im pretty sure it was a 60 amp fuse. i have think i have blown 4 or 5 fuses which were all at or around 60 amps. do i just need a stronger fuse? i checked the wiring to make sure it wasnt shorting near the battery but its not. thanks for the help.

like what amp. what subs. what your running the amp down to. is the amp playing for a short time then blowing or is it right away. is it blowing as soon as you hook the fuse in. is it blowing when your pounding on it.
if you wired your subs too low for the amp, your amp could be drawing alot of power and blowing the fuse. your amp could have a bad power supply causing a short. you could have a direct short by either pinched power line, screw through it or strands of wire exsposed. too small of a fuse depending upon amp.
too much to keep listing. but you get the idea. list more details.

sony class d amp 1000w at 1 ohm. it is 1ohm stable. i have 3 10" mtx subs wired in parallel for a 1.33... load. 600 watts rms. the fuse blows as soon as i hook the negative terminal back up. i tried to leave it hooked in and put the fuse in last but it still blows as soon as it gets put in.

something is shorting, you dont need a bigger fuse since any fuse blows immediately. take the amp out the car and test it with the negative and positive from car battery, you can use the positive for remote also. If the amp still blows then the amp is faulty. If not then there is something shorting in your car. Try to put the amp on carpet to isolate it from the body of the car.

ok i went and checked all my wiring. i loomed the power wire to make sure it wasnt in contact with anything. it still blows the fuse as soon as it makes contact with the other end at the fuse holder. could it be because i wired it up wrong? or a bad ground or something. i hooked up the rca's to the stock stereo with a line out converter and put the rca's into the mono input on the amp. (its a sony xm-gsd1600) i have the remote wire running to a switch. and the ground wire is bolted to a bolt on the right side facing the trunk a couple of feet behind the brake light. the 3 10" subs are in parallel for a 1.3 load and my amp is 1ohm stable. i hooked those to the speaker wire and to the speaker out on the amp. is this all right?

if you put a fuse in it while it not hooked up to the amp does it still blow with no load to it or does it blow when you contect it to the amp. if that is the case you might have a short in your amp but it blowing with out even being hooked to the amp you just have a short in your wire

ok, disconnect your amp. just the power and ground. tape up the positive end. put a small fuse in. if it blows you have a screw or something contacting your power wire and grounding.
if it does not blow then connect your ground wire to the amp. (make sure your hooking it up correctly. always double check) then hook up the positive. if it blows right away your power supply is shorted out inside the amp. send the amp out for repair or buy a new amp.
