I have 2 dvc memphis 15" subs.I want to put them in a center slot ported box.They are in a sealed box.My sony explode 1200 watt 1 channel isnt 1 ohm stable,but ive also got a SPL 1600 watt 4 channel amp it says its 2 ohm stable.Do you think this amp will work,and am i making the wright decesion by changing boxes.If the spl wont work what amp do you reccomend?
