My buddy and I are having problems installing his amp and subs into his 05 sunfire. The amp is getting power and all..but is blowing the 30amp fuse on the amp everytime we add power. We can figure out what is wrong. We couldn't get the powerwire ring to connect properly to the battery post because of the way its setup,so i had to strip part of the wire and do a quick rig until we could find a ring that would fit, and so far no find..anyways im thinking that might be the problem with too much power? any suggestions?
requesting help

The problem is not to much power.
If you keep blown fuses, obviously there is a short in the circuit... so the problem, I don't think, Is at the battery post. If the problem was at the battery post, the fuse would not blow.
However, there are aftermarket battery posts made for installing Multiple connections to a batter terminal. No need for crimping connectors, etc.
Trace all your wires, and make sure grommets are installed at any bends through sheet-metal, or any other sharp panels.
Also make sure the ground cable is secure and connected to lots of bare metal, there shouldn't be any paint near the ground connection.

As said, it sounds like a short somewhere, or the amp is bad.

Do you have a fuse at the Battery? If so is it blowing? If the fuse at the battery is fine, then the power wire is fine. If it blows as well, there's a short in it. If only the fuse at the amp is blowing it's sounds like a shorted or dead power supply = bad ampmpholt said:

Not necessarily a bad amp, could be a blown sub. Hook up another amp, if you have an extra one available, and see if it does the same thing. Could be a blow sub causing a dead short across the voice coil(s), thus showing virtually no resistance to the output stage of the amp.

Unless the amp is some $49 p.o.s. it will have short circiut protection and just shut down but not blow the fuse. I can short out any amp we sell and it won't blow the fuse, it'll just go into protection.DetroitBass said:
What amp are you using is the question?
