thats all space i have under the back seat of my truck. its going in a 04 extra cab silverado

im running a orion cobalt 10. with a 600 watt powerbass amp. its not a end setup but i just dont want it sounding sealed

i had them both on a small sealed box and it doesnt sound right.

the port is gonna be in the middle area where the 19 1/2 gap is

any help is apreciated. thanks

Can't tell what your port is going to be so there is no way to give you an answer, i would use 2 3" round ports near the inner sections 14" long so you will need to use a 90 bend near the back and that should get you tuned around 36hz. for some reason i subtracted the width of the board before my first calculation so i had all the wrong info plotted out. just use the same design minus what looks like your port and make it the rest of the box and you should be set

EDIT: For mistakes in calculations.
