[QUOTE="hispls, post: 8718166, member: 614752"] Port driver's side will meter best DB Drag style, Port up top will meter better USACi (Outlaw/at the kick). Center ports are fine for music. I'm pretty happy with the 2x4 skeleton we did in my brother's civic for rigidity. That + one layer of ply was sufficient there. Rough cut 2x4 is super cheap from a local mill here, if you're buying finished lumber it may not be a savings over buying many layers of MDF/Ply.. Before you get going, glue up some PVC pipe along one or both sides of the vehicle. That'll give you a route for wiring now and later if you need to add or replace anything. EVERYTHING else should be thoroughly sealed along the edges, top, and bottom. DO NOT skimp on thickness/layers. I used 5 layers for the baffle on my Jeep and in retrospect I wish I had done 7 or 8. It will flex without the steel bracing on top of the 5 layers (mixed MDF and ply). Buy a gallon of wood glue and some weenie rollers to lay down glue between layers. Wipe each piece with a wet rag or towel first, that'll thin the glue a little bit which is fine for doing layers, and it'll clean off any dust which may hurt the bond. Go as big as you can on the box and port. Way easier to shrink box or shrink port or lengthen port to adjust tuning later than to make the box or port larger or shorten a too-long port. [/QUOTE]
