2 alpine type r dual 2 ohm 15's

[woc47 10+ year member]

we are building a box for 2 dual 2 ohm alpine type r 15's to be in a ported box. these are going in a 99 dodge ram extended cab. Each sub will be run by a power acoustik class d 2400

Had these benched and they did 1250 @1 ohm

Taking out the back seat and was think of what size box to run alpine specs suggest 2.9 cu ft. per sub any ideas or suggestions would be greatly appreciated and has anyone dealt with the 15's before thanks

Tune in the lower 30's.

we decided to tune it right down to 30 hz, nmbr1spt has the pics hopefully he'll post them within the next day or two. The box end up being ~ 3.8 cu ft internal volume and 2.963 with port/ displacement taken out.

3ft^3 for both is not so great... also did you just pick them subs off ebay by any chance?
