any funky smell?

no... the amp will turn on as soon as the cars turned on then it shuts off... i usually get sparks when i take the fuse out or something and theres no sparks now so im thinkin it might be the fuse box but im not sure

no... i used a brand new fuse when i put all of it in... but i used a bigger fuse then what i used before so i dont know if that did it or not i used an 80 before and then used a 100A

What load is the amp seeing? I had a kenwood amp that would do same thing if bridged @2 ohms. Get a volt meter and check.

The KAC-9103D is a monoblock amp and cannot be bridged //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Additionally it is stable at 2 Ohms.

Actually it is claimed to be stable at 1 Ohm though I have serious doubts as to the validity of that claim...

MY point was that his amp may not like the load it's seeing and shut off. Or maybe it's seeing a dead short.

Does it shut off when you have no speakers attached? Also try wiring it to another sub or speaker. It could be a short in your subs. If not the amp is probably defective.
