Keep blowing fuses

I keep blowing fuses somewhere on my sub line. I usually blow the fuse coming directly off my battery... .sometimes Ill blow the fuse on the amp itself. Either way, the fuse usually goes right when I turn any power on. Iv checked my ground, looks good. Solid connection to battery and solid connection to amp itself. This set up has been working for a few years, now doesnt want to work at all. Any suggestions?

Where is your ground(s)? What gauge cable? You have one ground for the amp, but do you have any other components that need a ground? Also, check for any loose wires or terminations, and look for any wear spots on the + and - cables esp where it goes through your firewall.

Those are all fine suggestions, and they should be checked out. Now for the one that nobody likes. Check the amp itself. This is also them most troublesome to do also, as you need to swap it out with another one. The best way to do it is convince a buddy to let use use his car/amp. Swap amps out and if the fuse in his car blows, it is your amp. If the fuse in your car blows, it is your car. You need to hopefully find one that is comparable to yours. Also, I know that you said that it has been running for a while like that, but check, re-check, and then check it all again.
