Hi Guys,

I want to build 2 boxes for my Alpine type R (4 ohm). I would like to have them each in there own separate box just because of where I want to mount them in my car. I want to make a slotted design. I was also wondering if it is possible to mount these subwoofers inverted?

does any body have any input? I have a basic idea for the size of the box from the Alpine specs. I am just wondering about the slot. How big, how deep, etc. I am interesting in a cross section of the box and how far the slot goes down and the dimensions.
Also does any body have any idea if they would sound any good inverted?

i know they sound good inverted, ive heard alot of type R's screwed in backwards and they sound great, as for the box i have no idea... but ill do some looking....

or actually check this out - This site is great full of lots of helpfull info. PORT Size Calculations and Formulas for WOOFER and Subwoofer BOXES

spend some time on the site it has calculators to help you figure out every aspect of the box
