Going from a single Alpine Type-E (300rms), to these two type-r's, they sound incredible to me hehe. Im sure i could get the tuning better at the moment tho, i dont think i did the best of jobs. Either way, i think its pretty decent bass when i can sit in the car, and when the bass hits, all of the air around me gets slightly colder from all the movement heh.
I am gettin quite a bit of rattle tho, even with a ton of deadener. the roof has about 2-3" of flex to it on some songs. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
The box is 8cubes tuned to 33hz, pretty much two 4 cubic boxes built side by side. j3bus2k3 helped me design the 4 cubic chamber, then i just doubled it heh.
