alright thats cool, i do have a factory vent built into right rear fender of my car that has flaps that open under pressure, maybe i can modify it for breathing room? i'll play with it and let you know.

For what how to stop it? no its physics its just what happens.

do you have any suggestions?

When the trunk is popped it easier for the sub to move = louder Simple as that not cancellation or anything else its normal in trunk car's.

However remember the car acts like a chamber so when you open a door or a window or the trunk you create a bandpass with the open area acting as a port. a ported box firing into a car with the door open is a sixth order bandpass.

sealed box. and i didn't notice a difference when i opened the door, but i had already popped the trunk. all i had to do is pop the trunk(it only raises maybe 2 inches) and bass noticeably increases?

Is it a ported box?If so how long is the port?

I was thinking it was sortof like turning it into a bigger enclosure. I had a buddy up in Louisville, who had a demo vehicle and when he would open the windows or open a door it would get a bit louder. I know that is not the correct way of explaining it but someone can correct me, if that is im sortof on track.

Move the box closer to the rear of the trunk with them pointing back. Your getting some cancelation

got my new RE SE10s installed they are 11" subs listed as 10" apparently i had to cut the mounting holes bigger in my box. but they do sound badass, BUT i have a strange issue, the bass increases dramatically when i pop my trunk?? no matter which way way i point my subs its the same result??

Update!!

i ran the alpine imprint software twice and my bass is back, and clean, but i have a couple questions? what is the difference between reference and linear? i get 3 options to program 2 memory slots in my head unit, one is reference, reference with midrange(which sounds terrible IMO) and linear? and the tripod microphone, should it be set at ear height? or does it matter? i thought speaker timing was calculated by distance from ear area to each speaker? i dont think its right, i had to set it on the seat at ass level.
