That's my sub, and it's running off an old Profile Clarus CL800 at 4 ohms (subs rated about 600wrms iirc). I want to find another amp for the sub, still to run at 4 ohms, fairly cheap, and maybe to put out more power at 2 or 1 ohm down the road with a better sub (looking at FIQ15 for example).
Not sure how much it'd matter, but maybe D class this time. The Profile a/b seems a bit inefficient. Also not sure if there's many options for this, but one with bass boost with ability to adjust the boost frequency would be nice (just to try and slightly eq the low end).
Thanks for any ideas
