Manual states minimum impedance bridged is 4 ohms. Per channel 2 ohms. What you're doing when you connect the far left positive and far right negative of the amp is bridging, which will not support 2 ohms. You can use the left pair + and - but the subs are only going to get 200W on that amp any way you safely wire it.
Oh alright , lol that *****. But thanks for the input , Take it to a car audio shop? for the wiring , kinda new at this to be honest. If you blown the amp , what are signs of it?
You can do a small fix right away and that's switching from bridged to single channel. Looking at your amp, just take the - lead off the far right side and move it to right next to where the + lead is connected. See if this keeps your subs from shutting off. If it still keeps cutting off, you need to look into a new amp.

Easiest sign of a blown amp is the capacitors. If they're not smooth on top or there's goop you can't explain formed around the internals, it's blown. Will also smell unpleasant when you pull off the top casing.
Any updates? And what part of LA are you in? If you're close enough I might be able to help you out in the future.
