i have no problem with multiple amps its just that i want to hear everyone's opinions because i avent heard much about kicker but i hear lots about alpine and i used to have a pdx1.1000 and im kickin myself in the *** right now for selling it lol, its jus i dont know how 4 is a good idea, too bad alpine doesnt have a pdx 1.2000 i would buy 2 right now lol, and yes i realize they have the mrp m2000 i was thinking of getting 2 of those but i dont know where i would put them. the pdx's are stackable and quite a bit smaller. but im just here to get the expert's opinions on which product and company is the better buy.
