So a friend of mine has a Wrangler with a couple Rockford P2 10's in it. They're sealed right now in an ungodly small box. He's wanting more. I measured everything up, and I have enough space to build a recommended (by rockford specs) box sealed. I'm just over 2 cubes before displacements now. I'm thinking that I may have to build a "wall" up behind the rear seats (something he was hoping not to do) and then do external aeros so that I can get enough volume for both subs. Another option would be a single sub ported (likely with an aero) at the height he wants. Or the sealed route with 2 10's sealed in a properly sized enclosure.
So here are the options, in case you don't want to read:
1. 2 10's ported in less than ideal enclosure. The box would be taller than he wants it, and likely be hideous as no other, but this is the loudest option.
2. 1 10 ported in ideal enclosure. This would fit into his current space he's looking to give up, and would probably sound good.
3. 2 10's sealed in ideal enclosure. Not a bad option, but he wants more volume than he's getting from current sealed box.
Total size (as of right now, I might be able to talk more out of him) is:
Bottom depth: 10"
Top depth: 4"
Any thoughts or ideas? I'm going to talk to the guy tomorrow since this seems like a tough call...
