    Thanks...it does except for the sub on the right AA sent me a messed up re-cone a while back.....The coil assembly was glued in a little too high......That's why it has a dented dust cap........It didn't affect its output at all though........lol

    no great stuff foam for me.

    sealed off prevents phase interference from sound bouncing around in the trunk and arriving later. the extra output some trunks get is from constructive interference at a few frequencies (usually in the 40-60Hz range). but that means you also have cancellation at other frequencies. it is somewhat vehicle dependent since it relates to geometry. and it depends on the enclosure as well. sound off the rear of the sub will reflect off the rear box wall and come back out the cone. this plagues all speaker systems. controlling it is hard. it's why i gain output by opening my trunk. i eliminate the destructive reflections that come back through my woofer cones.



    have you been helped by me? i'd love to know. shoot me a PM.

    Re: ported box sealed from trunk

    the rear seat will actually help you by absorbing some harmonics - like an aperiodic membrane. i keep my ski-hole down most of the time - which allows plenty of airflow. but even with it up, i'm still happy.

    2.) what is usually the best tuning for a smooth roll off? or is this pure car dependant? if so im going to decide this for myself.

    3.) what do you guys use to seal the box from the trunk? great stuff in a black can

    4.) is there anyway i can seal off the box from the trunk and still be able to use my back seats? no
