Got one, thx for the input tho.
I haven't even hooked up the 1800 yet, I've been going on reviews and opinions from other owners. I just wanted a nice matching amp for my setup that started out being s single sub on 500 watts, to 2 subs on 1800, another 4 chan amp, etc etc etc.
And yes, **** that 900.4 is small. It's weird being back in car audio after a 15 year hiatus. 4 gauge power wire was freaking huge back then, if you needed that bigt of wire, you had a serious sub amp in the trunk.(I'm talking 800 watts at least)
