Ok, just built first part of my boot enclosure, i have a jbl gto1202d sub, it has 4 red and black terminals on it and the middle two have a gold thing connecting them together, do i need to wire my amp up to these ones? its a jbl 75.2 amp bridged to one channel.

That'd be the positive from one coil connected to the negative of the other coil. If you wire the other 2 terminals to the amp, then you'll show the amp a 4ohm overall load (which is what you want).
