Use a voltmeter and check you have 12v between the positive and earth terminals, and 12v between the remote on terminal and earth when the stereo is switched on. If you have these, then your amp is knackered.

You must be drawing too much current.
Try and connect the eart before you put the fuse in. If it still blows then maybe you have a short in the amp. Try a continuity check between the positive and earth terminals whith the wire removed. If you have continuity then your positive supply is being sent straight to earth when you connect it, this will blow your fuse.

It sounds like the amp may be shorting out internally. You need to use a meter to test the resistance between the positive (red) terminal and negative (black/brown) terminal. I think you will find that you have very little resistance between these, and this is causing the fuse to blow as you are probably putting the live feed to earth.

Not the battery - the terminals on the Amp. I suspect you have a problem with it. If you do, then you may need to have it fixed properly if you are not familiar with electronics.
