Default Box too big?

Ok i finally got my new amp, its is an eclipse ZA1200 running at 2ohms at 1200 watts pushing two 12 inch alpine type rs. It hits ridiculously hard but sometimes it doesnt pick up some of the low notes and then just BANGS on the higher ones. I thought that i read somewhere that if the box is too big it wont pick up some of the lower notes, the box is pretty big 1.7 each chamber and the type r'* manual says the biggest sealed box to go with is a 1.0 cubic feet per chamber.

Actually if you use a large sealed box it should be pretty flat and extend the lows well. You might want to try moving the box around in the trunk or face the box the opposite direction because it will sound much differently.

soyou got them in 1.7 each sealed? if so reduce the air space for sure. or you can try to mess with porting it somehow, half external/internal flare ports for example

stuff your box with a ton of cotton. it will take away from the amount of air space. but honestly I think you got your crossover set to high. aim for 80hz. and for future reference try to combine threads if at all possible. Just a heads up. what kind of box do you have anyway?
