i was wondering what would be louder? I had a viper 1200d on a 15Q.... I now have a massive audio P3000.1 and was thinkign about hooking two 12Q's up to it.....fist of all which one would be louder? Secondly would the Q's be a good mach for the p3000.1 considering it puts out around 2400rms is what i've heard.

I'd rather go with the 2 12's. More cone area, not going to run into power compression as fast, less cone movement needed to reach a certain level of output resulting in less distortion...pretty much a win-win any way you look at it
