    Default Polk Amp difference?

    I'm researching amps for my second car's system build and I've always wanted Polk amps but never tried them. So I'm looking into them now. Any SQ or power difference between the series? The class D amps seem to be smaller and more powerful but quite a bit more expensive. I love my D Xtant amps in my civic. But am I missing something?

    To be honest with you PA660/880 amps feel very cheap to me. Haven't used them, could be dead wrong but just going to Best Buy and playing around with them left that "cheap plastic" feeling.

    Class D amps - I bought PA4000.4 when they just came out and after lots of tuning back and forth I sold it for a lot less just to get rid of this pos. Sound was very dull and lifeless. My full "review" is on this forum somewhere, look up my posts if you wanna find it. Long story short I will not even consider today's (polk's) class Ds. Maybe as technology evolves it'll give it another shot but for now I'll stick to Class A/B for speakers and D for subs. I'm sure someone will chime in with "there's no difference between new class D and old AB, it's all in your head, people won competitions with full range Ds" but I'm not looking to start this argument, jut stating my own experience with the only full range class D amp I've used - Polk D4000.4

    As for PA500.4, 200.4, 250.2... i LOVE these amps. Had just about every one of them at one point or other, still used 500.4 and 1200.1 in my car for about 4-5 years I think and never had a single issue. Awesome full, loud, detailed sound, built tough, no cheap plastic feel, heavy grade yet slick looking. One downside is their size but I'll take that over lifeless music anyday.

    I've also used old Polk/Momo Carbon 300.2 amp which was nothing short of a damn beast. Lots more wattage than its rated for, insane brickhouse metal construction. Other amps from Momo series I'm sure are as good, cant go wrong with them unless you are looking for very small in size amps that weight next to nothing.

    The 660, 880 and that series arent that great. Id avoid them. Their new D line of amps seem to be pretty good. Im a big fan of class D amps because theyre so much more efficient and best of all, theyre so much smaller. Makes it much easier to install them. So yeah, Id highly recommend going with their D line of amps.

    I loved the first PA line of amps. Very powerful but gargantuan! Man those suckers were huge.
