[QUOTE="Jeffdachef, post: 8512615, member: 650438"] so how do you explain why my JL 6600 amp has a lot more midbass and upper end sparkle but only puts out 75ish watts vs the ppi which is closer to 140 watts from a direct swap as in with the first swaps it was flat EQ just to see the difference, then the next swaps were done fully time aligned, crossover matched, straight up SQ tuned, the ppi never could even get close to how the JL sounded. PPI was crazy amounts louder in the midrange but lacked top end detail and midbass impact no matter how much you try to boost. However the JL, you'd actually have to attenuate the midbass. Even my buddy's setup he heard huge differences swapping straight from a ppi 600.2 to a soundqubed 90.4(unbridged) everything SQ wise improved. All your amp choices were class A/B and not that bad on amp tier list. Try a cheaper class D amp and you'll be begging to come back to those amps. There's a certain threshold of quality you want to go over with amps. These cheap class D amps put out power as passmag and a lot of other people have clamped and dyno'd but the sound is just hollow. Even DereckBigDwiz who amp dyno'd a rockvill 2 channel making 600 watts said that even though it puts out a lot of power, the SQ is not there in a real setting vs other amps. Again i stand by not every watt is created equal, not one bit. How the amp amplifys and filters the signal is why higher end companies have R&D teams dedicated to work on those aspects vs cheaper companies just making things put out loads of power on the cheap.
