Have a Rockford R1000.1D amp that does 1k rms at 2ohms and wanted to upgrade woofers to get the best SPL and SQ for it and possibly for the price. I know Level 2s are rated at 600rms and 3s at 900rms but ive heard that DC subs are underrated and was curious what would be best? Ive been told to get a Level 2 by a few people already....
