2 of these and 2 Diamond Adio subs, let me just tell u this ...........THEY BASS, POUND WHAT EVER U WANT 2 SAY .... THEY HIT ,THEY HI HARD :)
This amp is kick a$$... I still have to get new subs for the amp but it even makes crappy Sony's Xplod 12's sound great.. This is the best buy for the price!
Bought this to power a 250W-300W Rms Sub (Infinity Ref 10in, custum inclosed box). Head unit was an IVA-D310...overall this sub was excellent and performed well...unfortunately I am starting to have problems. It may because I am in a 91 civic with a weak alternator. In any case it worked well for about 2 years. I also upgraded to a 10in perfect (@2ohms). No problem to handle this more demanding sub. Conclusion: Good value but quality is not the best neither is longevity, u get what u pay for.
If your low on cash and just need some something to give u 500 watts rms, this is an OK buy. however, one thing it lacks is "Over-Current Protection" meaning if you hook up a bunch of other amps or accersories to your car this amp will fry because the amp raises the current to supply the energy and then youll hear and see a pop and get the most disgusting smell in your car
