Weird...

Okay so my setup involved a battery in the back of my car which I ran my big Hifonics subwoofer amp off of, it's been that way for months. I recently got an old Orion amp to power my speakers, and hooked it up to that same battery. About an hour into playing the new amp it got really hot and shut off. I turned it down some and started playing it again about 10 minutes later, then it blew the fuses. I put new fuses in, it blew them immediately, I changed ground locations (to the same place I grounded the subwoofer amp) and it blew another set of fuses. I even tried unplugging all the speakers in case they were creating to much resistance or something and it still blew the fuses right away. So at this point I thought I needed a new amp, so I ordered one, and it too, immediately blew the fuses. The first amp only needed a 40 amp fuse, this one is only 15 and I'm using good 8 gauge wire. Also the fuses that are blowing are the fuses on the amps not the fuse in the wire next to the battery which is the same size.

Kind of on a side note I was playing around with stuff trying to figure it out and I noticed that if I have the ground off of the speaker amp (I believe it only does this with the ground off) but the power hooked up and the remote wire, which is secured to the same remote wire going to the sub amp, and I try to put a fuse in the speaker amp it turns on my sub amp. Even with the keys out stereo off and everything. I don't get it

 

I tried that yeah, i've been trying it with one also

 

No the other amp doesn't stay on all the time.

I tried hooking up only the power and the ground to the rear battery and the front battery and it blew the fuses both times. Sound like my wire is just fried? or maybe my fuse holder is defective or something? Cause it's still only popping the fuses on the amp not by the battery
