Need help sub box 2-Fosgate 15" p2 8ohm scv- toyata corrolla 97

[jhiggsaww]

New here guys but always browse and check everyones stuff out. I have a 97 corolla and actually had these 15's for a while and can you guys or someone help me out with a box that will make these bang, forward facing through rear seat. Alot of guys out here in alabama say the woofers hit harder facing the back of the trunk and i've heard the diffrence and they are right, I guess. Thanks

Maximum dimension for a box would be helpful. Fifteens in that trunk facing forward will be difficult.
