Trouble with Ampand 12" sub, need some help!

[95mustanggt]

I've installed a new Pioneer deck into the wife's 97 Crapolier. It works fine. Now I go to install a Sony Amp and 12" sound stream sub and I'm having problems. Here's what I have:



Here's some background

The system was originally powered by an Alpine 80W amp. I removed the alpine and replaced it with a MONO 1000W@1 ohm amp.

The original power lead was all 8 gauge. I moved the amp and I am using 6 gauge wire. This is why there is a difference in the gauge of the wire. The instuctions call for 4 gauge, but I was told 8 gauge was minimum.

Problem

The deck works just fine.

If I hook up the amp with no sound the power light comes on and no diagnostic lights come on. This is with the sub disconnected.

If I connect the sub, weather there is music or not, there is only a loud fog horn like sound. When I had a smaller (and cheaper) fuse in the system it would blow the fuse. I now have an 80 AMP fuse (which is what is called for). I just yank the wires or disconnect the face plate before the fuse blows.

I measured the resistance across the speaker terminals on the sub box and it measures 1.6 ohms. The sub is a 12" sound stream sub, which if memory serves me right (this was almost 8 years ago) the sub was a 600W sub.

Can anyone help me? I'm going to disconnect everything and re-try the alpine amp, but if you see any major short comings with the circut above please feel free to make some suggestions.

Thanks.
