will this box be big enough for 1 10" level 4 xl? this box will be going under my rear f150 seats. it is a sealed box but i need some help designing it to be a ported box. but overall i need to know if there will be enough mounting depth to fit a 10" level four xl. Thanks

The XL would work in that box and theres plenty of airspace, I would port it for sure

thanks! but can anyone design a ported box for me using those specs? i dont have the software to do that

I would try and contact phil from woodlawn cabinetry. I've seen a bunch of builds of his for under the seats of trucks and they're amazing. His username is Mr Cabinetry. I had a 10'' lv4xl and I did a 1.7@36 and a 1.5@40 and both were real loud and got real low even with the higher tuning. I'm not sure on the airspace of your box but if it's well over 2 cubes I would use a slot port to take up some volume inside the box but if it's under 2 cubes you can get away with a single 4'' aeroport.

^^^^ Knows all about 10 inch XLs in trucks =]

i can do it.

send me a PM

(The design, not the build....not yet anyway...)
