[QUOTE="salad fingers, post: 6667144, member: 612184"] I've got an Alpine Type R 12" dual 4 ohm brand new still in the plastic wrapper from Alpine and a Diamond Audio D3 800.1 that does 600 RMS at 2 ohm and like 800 at 1, so there is some room to grow. $250 shipped for the combo. Retail on the amp new was $499 and the sub is $250. Let me know!! And yea daboyfrumdabx has a valid question, two channel amp is going to do all of it's power at 4 ohm bridged (except special cases like JL slash series and the Zapco amps) and are many times class AB and less efficient than a mono that is class D and optimized for the bass frequencies.
