if your fuses and install are correct, you shouldn't have to keep replacing. it should protect your install and amps and other components of your audio system without blowing. and a circuit breaker gets a little weaker every time it breaks. eventually it will offer you no protection. everyone who knows what they are doing uses fuses and there's a good reason for that.
x2 on the second battery...and put some terminals on that box son...no wiring going in\out of the port! that's ghetto!
but especially for a 1st install it looks pretty good. just gotta finish up that box with some paint or carpet.
well then thank god you upgraded. but maybe search that amp for a model number and search for it online? that should tell you the output of them. and for god sakes, get rid of that power acousitik cap...sell it and upgrade your big 3 underhood wiring.<br>
