I need to hurry up and find a great pair of 15s for my Directed 1100d. They will be in a sealed box facing out in my Explorer. I just want something that hits really hard. Can someone give me a few choices? I've looked at the Audiobahn Ultra Excursions(too pricey),RE HCs(I heard they dont do good in a sealed box),and RF Punch HX'2s.I really dont wanna buy a pair of 15s that **** and I have $600 to spend on subs.I basically want major spl(I'm not gonna go ported though) and I want to get the full potential out of the subs.
