you can look at the sq post, many of them are not running rear speakers so why dont you buy a spr 60
and a four channel amp bridge two channel for an small sub with a nice hu?
i do some homework maybe you like this
hu.- pionieer deh 80 prs $235
speakers alpine 60 c $ 150
alpine PDR F 50 $ 300
alpine swd 8d2 $ 100
total 785 (
amazon prices)
nice componets for the bucks, running them active all, you can set all your xovers, and time aligment the way you need
how?
tweets directo to hu yes tweets will be getting 22 watts each
mids to two channels of the amps getting like 80 watts
sub two channels bridged getting 280 watts
i think its a nice set up for you to start in sq world,
well thats my opinion and options
