Keeps blowing, need some help

[strawsy]

I just got my new system, built my own box. I have 2 kicker s12l7s and a hifonics bx1500d. The subs are in a big ported box. but my problem is i keep blowing fuses the amp is 4 guage thats what power wire i have, the inline fuse is whats blowing it was originally 80 but it keeps blowing those, i dont know if theres a bigger fuse i can get or what but somethings wrong....everything is hooked up good. If someone knows what their doing please help me theres nothing worse than having a $1400 dollar system and it not work.

you have a short somewhere on your 12v powerline ... or your amp's power supply is bad.

ok what is the 12v powerline, and how would my amps power supply be bad. If it is one of these how would i check to make sure and what would i do. thanks for taking the time to reply

you kinda have me worried now, your not saying my amp is bad are you?? cause i just bought it

the thick cable that connects your battery to your amp is your 12v powerline. re-check that entire cable run, and make sure the only exposed wire is on the ends where they have solid connections. if you have a voltmeter built into your dash check that your output voltage is between 10-17vdc, because current (amps) is directly proportional to voltage. more volts = more amps, and if it exceeds your fuse rating it'll blow. if you need to, use a stand alone meter to gauge your output voltage.
