View Full Version : Help with box size for Alpine Type R 12's

Right now I am pushing two alpine type R 12's with a 1500 watt 2 channel audiopipe amp at 2 ohm's in a sealed box at 5 cubic feet.

wondering what size my box should really be? i'm also thinking about going ported or vented? louder cleaner? help me please

Ported will be louder. IDK what the recommended size for the R's is, but my type X was nasty in 2 cubes at 30hz (setup in sig). YMMV
