Alpine Type R (SWR-1242D)

Was thinking about buying a 12" Alpine type R but I have limited space for a box in my '97 Grand Cherokee. On their website they recommend 0.7 cubic air space for a sealed box and the measurements are 13"x13"x13". This would probly work for me but I didn't think these subs did very well in a small sealed box according to some posts on this forum. Also they come in dual 4 ohm and dual 2 ohm, which would be better??

i have a 12" Type R, but its in a 3cf box tuned to 30hz, getting around 700rms..so i cant really tell you how they would do in that small of a box.. also, i am not sure on this.. but that box would be a square shape, and i dont think its a good idea to have a sub in a square box.. but better in a more rectangular box.. also im looking at pics on Cardomain of your year, and theres all kinds of setups..

you have quite a bit of room.. you could fit my box in there with no problems...

and this dude has a 8cf box in his!

anyway.. heres my box specs.. if you get the 12" Type R.. you can use this box.

It depends on what Amp you are going to run on it... Personally i love these subs, i have 2 in my buddies truck each sealed 1 cuft and they pound hard... But other guys here have some Type R's in a ported box and they are really loud something like 142.7db i heard. But if space is an issue 1 cuft is fine for those subs if its sealed, They are nice subs for the money

I had 2 of the new Type R 12's for about a month. They're good subs. I tested one and it took 800W RMS with ease and really could use more. Really nice low end and decently loud for the shitty enclosure i tested it in.

Great subs for the money but i would say definitely go with Scarrells idea of taking his box design, if he hit 147.9 in it i would say go with that design all the way!
