trying to settle on an amp for 2 dd9515 4 ohm subs. i was told class a/b amps would be best suited for setup because they are better for SQ? with that being said what amps do you guys recommend?

I dont know bout the whole "class a/b amps are best for sq" thing, but i would try for a class d amp because they dont get as hot.

go w/ a clas-D amp...they are alot more efficient. and w/ the amount of power you would want to run on 2 9515's, you are gonna what efficient amps.

^^^agreed. Class A/B amps I would say are more for speakers and class D are better suited for subwoofers. Overall, i'd personally go with class D amps for everything.

wow, then your system would sound like sh1t!!!!! lol

and don't say "well i would have fullrange Zapco amps"...b/c those cost and arm and a leg

Class D amps were produced for high power applications, thats it.

you can argue technical specs alllll day, but i have heard subs with Class D amps and Class A/b amps....and the class a/b amps just sound cleaner to me...not as sloopy(might be a dampening thing) and not as boomy(might be a BB thing) but overall....they just sound cleaner.

my whole system is run on Class a/b amps...and i can't complain about not having enough power. lol

i agree with marshall though, for the kind of power yu are looking for 4-6kw, class D's will be your best bet.:-)

can someone explain to me why class ab amp would have better sq than the class D on subs?

most likely you are not going to be playing freq above 90-100hz on your sub so what would a person benefit from a class ab?

w/e dude.

it doesn't matter....it more than likely is ALL install and user knowledge. but if you used a class D on components...it wouldn't sound good...and simply knowing that, i can't play my subs with it even though i can't hear the distortion at that low of a freq. CHAD!....

I use all class AB amps in my system, but really you won't her a difference with a class D amp on subs, if you stay below clipping. A class D amp will run cooler and mroe efficiently as well.
use class D for subs, class AB for full range.
