As u may know same company owns all 3 brands but for the obvious reason that the PPI is 1500wrms as opposed to 1200 for the other 2 - i'd say PPI (though IMO its the ugliest of 3 -lol !)
yea accually there all pretty ugly but w/e lol and i been lookin up stats and none of them say 1 ohm just 2 ohm which is 1000 rms but thats all i need for a 15sx
also i just traded in and got the p7700 it looks really nice and sounds alot better than the boss but the bass is very muddy i cant get it to be punchy again i think i have to tune my amp right because its not the eq on the HU
