Is it reallt bad if their is no fuse in the power wire between the battery and amp. What will go wrong if their is no fuse?

 

Always run a fuse, about a foot from the batery. You need to have it to prevent your amp from blowing, if there is a surge of any type it will toast the fuse and not the amp!

 

actually, the fuse is to keep your car from blowing up.... not the amp!

 

run a fuse!! I would hate to see you posting pics of a charred f-bod.

 

But there should be two. One under the engine bay closest to the battery. The other should be next to the equipment to protect the amp.

If something goes wrong, normally the amp will catch on fire and ultimately catch the car on fire. Technically, the fuse is to protect the amp.

 

The amp should have at least one fuse on it's back panel, that is to protect the amp from surges. The battery needs to be protected also, get a good line fuse holder and use it.

 

Hopefully you've got enough feedback now to realize running without a fuse is very dumb.

The fuse should be as close as possible to the battery and be as close as possible (but not less than) the fuse rating of everything you are running. Anything up to 80 amps can be handled by a very inexpensive tube fuse holder.

You can also pick up circuit breakers to accomplish the same thing. They cost a little more but offer the convenience of never replacing a fuse and being able easily open the circuit if you're working on the wiring.
