amp speakers subwoofer

Hey guys i need some knowledge i acquired a tri-box with 3 Alpine R-type 12's and a Quantum Audio QB1000D MONO 1000W 2 OHM CLASS AB AMP. I have hooked up the left and right one and it sounds great. I want to hook up the middle one but the question is how should i do that? Bridge it? or just plug...

Hello, i got soundstream rbt 653 3ohm speakers 100rms watts, and i got gothic 1200w amp 4ohm and do i connect the speakers straight to the amp? or do i connect them to the stereos to? i already connected my subwoofer and the amp,
