Thanks guys!
Quakerroatmeal: Yes I must invert mount them, very tight in the first chamber.. about 3" I think.
Jimmytheheater: If you have tried an diesel XJ you might change opinion, these are extremely slow.. haha, so with my stereo system its not fun to drive. But ofcourse the 4L wants some more fuel..
Woofers and batts are wired, heavy a$$ Jeep!
Have been testing a little now, and I'm impressed and happy how it turned out! This plays loud and nice, and pretty good from about 25hz to 100+
Voltage on idle is around 14,4 - 14,7 when I play, and 15v on 1500+rpm.
First test, peaked at 40hz. Woofers are not break in, wall is not sealed off and nothing is fine adjusted. A lot of roof & door flex etc so here is more potential! But I'm happy with the results, and since its my first real build //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
