I have a ED Nine.1 and I need help deciding on what subs to get. The amp supposed to do 1200w RMS @1ohm 12.5v. I have a MB Quart 4125 powering a pair of ID CTX65cs comps and a pair of ID CTX65 coaxials. This is all going into a '09 Jeep Wrangler Unlimited. I listen to all types of music. I want something to get low and loud. Would 2 Icon 12's be a better choice than 1 Xcon 12 with that amp?
