    sealed off trunk help

    well see that's the thing. I thought I just sealed off the trunk badly so I closed the back seats up and put the box on the seats and it got even quieter! I think a lot of the reason I'm losing spl and airflow is because my box and port are pretty small in comparison to those guys. And I don't know the size I would have to measure later and tell you

    the dude that made it said it was tuned to 30hz but I don't think it is. 30hz isn't that loud and it hardly plays anything under it. I did a bass test and the loudest sounding note was around 40hz

    sealed off trunk help

    i have an FI sp4 15 in a 2007 nissan altima and recently i tried moving my box around to fire forward like a sealed off trunk. I put it as close to the cab as i could and put pillows and sheets all around the box stuffing it as well as i could, and it wasnt as loud (sounding) as firing it towards the trunk. i then folded my back seats closed and put my box in the cab on the seats so that it was completely sealed off from the trunk ( i have a small box and plan on getting a bigger better one) i tested it out and it was even quieter, like a lot quieter, it had less pressure on the ears, less airflow and everything. Ive talked to people and they say sealing off the trunk sounds way louder but when i have tried doing the same its not even close. What am i doing wrong?
