2 12" Type-Rs in Chrysler 300m

[dwz]

Check it out!!

Using Polyfil to experiment, effectively making the box 4.4~ cubes @ 33hz (hits the lows a lot better, sounds louder and smoother, but doesn't shake my car nearly as much)

UPDATE:

I took out the polyfil, and the sound is not as smooth or low, but they definitely POUND harder and hit your chest rather than your ass. They hit all the notes better, but sometimes I do hear port noise. But I can see why one would like Polyfil better. I guess it's personal preference.

I put the polyfil in my spare tire well instead

nice man! trying to hook up my brothers car right now, he got a 12 type r right now and he bought a t1000.1bd. we gonna build the box this weekend and hes gonna buy the other type r soon. then we gotta wait for the aero ports to come in thursday. im a little nervous cuz this is my 1st time using aeroports but everyone said they good. is that 4.4. cubes after dis? his box is gonna be 3.3 cubs after dis tuned to 32hz. i thought 1.75 was the max reccomended space for each 12?

yeah bro they're great cause you can save a little space since aeroports need less physical port size... all the measurements I'm giving are w/o displacement. I have 3.3 cubes right now. 1.75 is about what the alpine specs recommend, but I've seen posts on here (do a search) that say the type-r's do well in 2.2cubes each /w twice the port size... personally man I think mine sound perfect in the alpine spec. they're very boomy and they hit ALL the notes. I would imagine a larger box would make it sound pretty flat.
