blown fuses

[sicandtwisted06]

i have a rockford fosgate punch amp, ive had it for over a year now, and all of a sudden it started blowing fuses. i can have the battery, REM and ground hooked up, and as long as i keep my speaker wires out it dosent blow my fuse. i can connect the positive speaker wire, and as soon as i touch the negative wire to the amp the fuse blows, on the back of the amp. ive changed the fuse case on my battery line, and ive checked my ground, but the fuses keep blowing. any suggestions?

1...Are all connections to the respective GROUNDS, not to the FRAME/body..
2. TURN IT DOWN if possible...
3. GAGE of wire being USED?
4. ANY connections that ARNT SOLDERED/COATED/CLEAN...Are suspicious..
5. + to + and - to -...PERIOD...ALWAYS check...OVER AND OVER.
6. BAD speaker.
7. BAD amp..

well for the ground ive always used a small hole on my trunk, i took a wire brush and scraped it clean of paint, and i have a bolt holding the ground wire. i thought my wiring kit might have something to do with it, when i bought it, it was for my previous amp. the kit was only rated up to like 5-550, and my new amp can push out nearly 1000. i guess i will try replacing the whole wiring kit. is there anyway to check if my amp is blown?

A good ohm meter, which most of us cant afford..
Or Direct connection of Speakers, that you know work...
Connect Ground to ground(NOT the body of car) and + to +, USE LOW volume..

where can i connect the ground to, besides the body of the car?

TO THE SPEAKER...thats why there are 2 connections.
Also make sure you are using the correct side of the amp. OUTPUT side.

Hey Sic--

You could also run the ground directly back to the Neg terminal on the battery.
Before doing that, and cross checking all the things that were mentioned before, you may want to check a few more things.

A. Is their any moinsture near or around your amps, or ground wires?
B. Are any of your wires frayed and could be touching something causing you to blow the fuses?
C. Do you have the right size of fuse in your amp

Another good point that was already brought up was the guage of the wire. If your using 16--go to 8. If your using 8--go to 4. If your still blowing with 4, get a new amp or take it to a dealer and have them test it for you. RF makes great amps, but every company can have a few units that go bad.
