get:

a 2 chan for fronts OR a 4chan for all 4 speakers.

AND

get a monoboc for your sub duties, not two 2/4chans for each sub.


now that you want 2 subs i dunno what voice coil subs to suggest for you cus i dunno what amp you're actually gonna use and what its stable down to...

wouldnt you rather 1 better & higher quality sub than 2 cheaper, lower spec subs??
