swift terminal sub wiring
 

I have two rocksford tod212 subwoofers and they have swift terminals on each sub so it has one positive and negative on each sub and a fuse and one side of the fuse says 1ohm and the other side says 4ohm and I do not understand how to wire them at all I have a attrend dual slammer box and the box has one positive and one negative on each side of the box just like a normal box does for two subs I put the fuse to 1 ohm on each sub and wired it negative to negative and positive to positive to the box on both sides and my amp kept going into protect mode and yesterday I fried my amp so I think it was just the way I had my subs wired
