I whould definelty want to go ported if i go with 1 Type R 12 or 15.

Since its in a SUV im thinking aim the sub up and the port to the rear.

I would say fire the sub rearwards and face the port upwards. This way you get the nice backfire (depending how far the box is from the "tailgate?" or back "hatch?") from the front of the cone, and the back of the cone fires through the port. It will take some "moving around of the box" to get both the front and back waves to travel in phase to the front, but owwww, loud. I would especially recommend this for the 15......just my opinion though.

sub up port back or or both back works the best in an suv

dang, this thread kinda went to hell, lol... anyway.. i did to a 147.9 on the AC.. also i have been metered on a Termlab i believe, and i do have vid, the reason why i am not sure if it is a Termlab is the people hosting the show didnt know anything about it and they didnt even set the mic up or nothing, so i dont know.. i wasnt really thinking about it at the time, but a friend of mine said it was a TL, anyway, i did about a 142 playing Throw It Up by Lil Jon.. but later to find out that my sub was actually coming lose from the hole and falling out, so im sure i could've done better.. but either way, its a good score to me.. and i hope to get metered again, and this time find out for sure if ill be getting metered on a TL, anyway... you can put quite a bit of power to the Type R's.. you can do that with just about any sub that has a decent motor structure and such.. i talk to a guy that has three 15" Type R's, each getting 1600rms a piece.. his name is Galactic Monkey, you can see his vids on Realm Of Excursion, pretty amazing stuff.. theres also a guy who has a 10" Type R, that burps his on an Orion 2500D doing almost 150db or so on the TL with it.. but with my experience.. id say 600-1200rms would be good for daily use.. anymore wattage you would have to be pretty dang careful... good subs yes.. especially for the cash and quality structure and sound.. there is better out there, but for the kind of money you can get them for online.. it will be hard to beat.. thats all i have for now i suppose..

Alrighty then, I just ordered an Alpine swr-1242d (12" dual 4 ohm) subwoofer. I will be using a small sealed box for this. What amp would you recommend?? 2 channel or mono??? I am looking to get a Hifonics amp.

Im trying to save space so maybe i will get a Type R 12 and go ported due to the box design being large with the 15. Im still not sure which amp to get.

That is good info to know. I have not really gone extensive with porting in SUV's. Sealed I have built boxes high enough where the subs cleared the height of the backseats to allow full front wave into the cabin, but other than that, not much porting experience in SUV's.....thanks for the info!!!!!

ive heard a few SUV's with the subs up and the ports at the bottom facing forward.. they had good results..
