Re: will these amps work good with these speakers/subs?
First setup is fine just be sure to get the right ohm subs. You would want dual4's.
Second setup like bett said above not going to wrk. Get a 4 channel amp and then yes it would wrk. Need amp that does 100x4@ 2ohm as those GTO's are 2ohm which is fine and will be good for u as a cheaper amp can be used.
