    Why is this amp cutting out??

    Whats up guys? Well i got some loaner subs and amp till my blueprints come in from a freind. They are three Pioneer 8s with a crunch 600 watt amp. We put it in today and ive been driving around listening to it tonight. It plays awsome for like 10 min. then the amp shuts off. If i turn my head unit off and on it starts again then blows a fuse. Im using 25 amp fuses in it but i might go to 30s. The amp isnt getting that hot and is well ventelated. Any ideas? I just want this thing to hang in there for a few weeks till i start running those blueprints! Thanks guys!

    upgrade to a bigger fuse, either 30 or 35 amp fuse and see what happens. If it stil is blowing the fuse make sure all the wiring is done correctly and that the positive wire isnt cut touching the frame anywhere along the way or something like that. If you know ur wires are good and its STILL blowing the 35 amp fuse go up to a40 or 45 but that amp really probably doesnt need that much.

    Yes I agree with Savage..check your grounding point and start with one sub and play it for awhile and move up from there.
