Polluting Residentials
Keep in mind, that a direct swap of generally comparable subs will likely only gain a few tenths on meter, and might not be audible.
It is a fallacy to make a blanket statement that all 2.5s will be louder than 3s on low power, but the reason I made that claim is that we are talking about strong motor subs. Ultra, fu 750 and ill add the twisted tsx in there.
All 3 of those will be louder than something like a lvl 3 on ~1400w.
Your best bet is to add power. Go up to a legitimate ~2500w amp. Your SAs will actually keep gaining well above 700w a piece. I had 2k on 1 and it was way louder than when i had 750w on 1. I went from 139.1 on 750w to 142.2 on ~2200w (trunk car)
