what could i put for subs if i want 2 12" about 500 watt peak and amplifier
is MTX good enough i dont want expensive **** mild stuff will do

 

MTX does make some nice subs (and some crappy ones) ... there quality is probably comperable to other brands at the same price points. Find a place (store/shop) where you can audition different brands of subs and see what kinds YOU like. My advice: don't rush into anything and spend some time shopping around. Also, don't buy a speaker because of the brand, or color, or because this sub is rated at 400w and that one is only 200w ... buy it because you like the way it sounds.
