Getting ready to start the boxes for my two 12's PG rSD's. Ha in a jeep wrangler so these boxes are going to be fiberglass around my tube frame. Anyways before i finalize everything i wanted peoples opinions my plan is 2cu at 30hz for each. Wanting some really nice solid low's but be able to keep up with the higher bass. I'm thinking i may lose a little of top end with it at 30 but think those lows will make up for it. This is my first time working with glass, on a box atleast i've done body kits and such. i'm going to be using fiberglass mat, around a frame that is going to have a base of 3/4 mdf that is bolted to my frame. Doing this so i do not have to touch glass to the jeep. Do you think i'll get the sound i want out of this? please let me know im very underexprience is the diffrenent "sounds" of woofers.
