Last night, i've wired up everything, from rca cables, remote cable, power cable with a fuse, and the ground(short cable), all leading to the back of my trunk. I wired up the ground and the power to the amp and POOF the 2 fuses on the amp blew, so i went to ralphs and bought 2, 30 amp fuses, and tried again, POOF again, it blew, and i tired this 2 more times. the fourth time, i had the 2 30amp fuses in and the ground cable in, when i stuck the power cable in, my 60 amp fuse POPPED inside my hood,
My question is, what are the steps needed to install the cables without breaking the fuses? Is it ground cable, and then the power? Install everything first and then finally the 60 amp fuse at the end? Please help me out, i greatly appriciate it. thank you from mark
P.S. please email me with the responses, that'll be super!

Fuses blowing huh.... usually means a short circuit somewhere in the power feed line or amp problems internally.
Is this a new amp? What amp is it?
BTW, when installing amps and such in a car, the main power line fuse is the last thing to install.
May have to remove the amp and bench test it with a 12 volt power source, audio signal input and a speaker attached to outputs. Yes, do use an inline fuse when testing as well to protect your 12 volt source. (Car Battery& Battery Charger or a commercial grade power supply that can deliver at least 30A of current at 12-14 volts DC.

oic, my friend told me to take off the negative battery terminal and then wire the amp up and then put the negative back on, is this true? the amp is new, its from alpine. thanks for your help guys!!

if you unplug the negitive cable off the battery you can still gorund out i belive. anyway its god practise to remove the power line fus anytime you work on the amp.
no matter which way you hook it up though usualy you wont blow a fuse if the amp is off... i have only blown amp fuses when there was a short or speakers where wired wrong...
you either have a short in a wire somewhere or this amp is no good. if this amp is brand new never used it could be a factory defect.. as swez suggested this amp should be bench tested to be sure it works....

Yes, disconnecting the Neg BAT terminal is a good idea for beginners who are not very familiar with wiring powered devices. This can present some problems with cars that have anti-theft codes in their HU's. If you don't have the codes, the HU won't work until the proper code is re-established.
Since this is a new Alpine amp, you can either return it to the place of purchase and ask them to test it out or try to diagnose the problem on your own. Not knowing how it was wired up, hard to say what is causing the fuses to blow. Common causes include:
1. Shorted speakers
2. Shorted speaker wiring
3. Speakers wired incorrectly
4. Reversed polarity on power terminal and ground
5. Main power feed wire is grounding out (short circuit)
Good luck,

It definitely has to be a short circuit... check the integrity of all your power cables, grounding cables,reminder cable and speaker wires.. also try running the amp with individual speaker loads one by one.. cause this cud also happen if even of of your speaker is shorted..try doing this.. and let me know i have something else on mind too.. but first lets see if it gets solved by this excersice..
