1st off im new so hello everyone. i own a 97 f150 ext cab. i just bought a used q-logic single 10" box for under the passengerside rear. it doesnt fit? do i need to raise the seat if so what are people useing to do it. thanks for any help.

 

I think you bought for the wrong year. The Q-logic website only shows a 8" version for the 97 ext cabs. Later models can fit a 10" box. Best return it for the correct box or build a custom enclosure.
