I have two audiobahn 1800e mono amps (2 ohm stable )and 4 audiobahn 10" aluminum DVC (daul voice coil) subs. As of now I have the subs in a sealed box and are run in series/parallel (4 ohms). Could anyone tell me if I should leave it as is or if there is a better set up I could go with to get more thump such as if lossing two subs to get 2 ohms of the amps would that get me the bass I desire??
