4 Rockford R2 12s Box help

Recommended Posts

Sister wanted a temperary set up while she saves the rest to wall her 02 Explorer. Ended up getting 4 Rockford R2 D2 12s. Going to be run off a Rockford Punch 1000 ( Birthsheet says 1200-1300 ) at 1 ohm. Thinking the best scenario would be subs up port back but im unsure about tuning. Subs say their response is 43-250. Is tuning to a daily 34-36 safe? Also what type of port area should i be looking for? Obviously not dealing with high Xmax subs and whatnot so not sure on that either.

Max Dimensions Are:

19" High ( This is to the window line to allow her to compete in Beginner Class if she wants, but can go higher if need be )

28" Deep ( which leaves room for the port to breathe, around 5" from rear gate )

44.5" Wide

Subs Up Port Back is my thinking and possibly doing a flush baffle, not a full double baffle and tuning around 34-36hz if the subs can be in a box that low ( like i said the response says 43 so not sure about that )

You're not going to get huge output from those things, you probably know that though. Are the subs bought yet?

If they are, go with 50" of port or so. A 5X10 bottom slot port will work fine.

Fosgate has the thing tuned at 45 Hz with rolloff happening at 39 Hz

I would make sure you get the 1.75 cubes per sub. That will put your box at 7 cubes net after port and sub displacement.

Im not the one you want to try to troll. Just a fyi for you.

Should i uning higher to 45hz then? Or tune lower like 36ish and just set Subsonic a bit high? and i was going to do a center vertical port, unless center bottom you think would work better....Thanks for the inputs!

subs are about to be bought...other suggestions for 163 bucks? lol in the 800-1000rms range
