Okay, so a.....


12" RE SE
2 feet^3 (For the sub, after port displacement...)
Tuned to ~32 hz


According to this http://www.carstereo.com/help2/Articles.cfm?id=31, I need ~32 in^2 of port area (going with a slot port, 12.75" x 2.5") Now it also says it needs to be 29 inches long....is that correct? The port is kinda concerning me...

Right now I have a JL e1200. Not sure how well it'll push the RE but ported I'm sure it'll do fine. It managed to blow my 10w3v2 quite easily in a sealed box, pretty sure that was just clipping though.

Yeah, all I've found there is that I need 2 cubic feet after port displacement....any link to specific port info?

Heh, have to look at the box, not even sure, not sure what it really runs at either since there is no birth sheet.
