Your amp cannot be bridged into 2-ohms. The only way to safely use this sub and this amp is to wire the VCs in series for an 8-ohm load and bridge the amp (or wire each VC to an output channel separately, which results in the same net effect.) Will it do the job? Sure. Will it drive the sub to it's limits? No. Will you like the result? It depends, try it and see.

Looks like it's 2-ohm stable, so sure. Is it a Bazooka? You can probably get a better brand than that. How much can you spend?
