Posted in another thread a couple days ago...

My friend wants to get 2 12'' type R's. how many cubes should the box be? Sealed or ported? What size amp should he use? gauge wire?

Get (2) Dual 4 ohm Type R's , Get a min of a 2ga. amp kit, get teh absolute kit from onlinecarstereo.cpm

For the box make it 5 cubes @ 34 hz.

Box specs: 36"x14"x26" The port will be about 6" wide and will be 18-19" long.

Amp: Planet Audio VX2200D, it does 2krms on birthsheet. It wil def push the R's to full excursion. Be carefull though, you can blow them with this amp.

This will flex windows of buildings, pm me for video.

Here is a pic of the 5cuft box I made for mine...
