Well first of all i want to know if i got a good deal? i sraight up traded my 2-10" audiobahn 400W subs and a DHD 200+200W amp for 2-12" Diamond Audio D1 500w Dual voice coil 4 ohm subs and a 1200W Sony Xplode amp. The amp is stable at 2 or 4 ohms. When i play the subs for like 1/2 hour they will like stop playin for like 30 seconds and then they'll strat playin. I have the amp bridged right now but i dont know if i am able to?
