One of my subs recently broke. Since the option of fixing it seems hopeless, I now have a box built for 2 12" subs. My budget for new ones looks to be around $300 total, give or take a little, and I already have an 1800 Soundstorm amp waiting, already wired and everything. I was looking at the Elemental Designs 13Ov.2 and was thinking that would be the size I would want. Would I want to try and either add another amp or buy a newer, bigger amp for those, or would my current amp be fine? My current amp puts out about 450W RMS or so and these are rated at 600W RMS
