I have 2 dual 2 ohm alpine r's, 12 inch 2005 model. Yeah, everyone copied me.. joking. But i had 2 of the older ones that were 300 rms and this amp pushed them pretty well, but i don't think its powerful enough for these ones. They can take 1000 rms combined and the amp i have (mtx 801d) is usually putting out 500 rms and 800 rms at 14.4. Therefore i think i could use a 1000 rms amp at 2 ohms. Anyone have any suggestions, i have about $500 to spend on it.
