2 6.5s sounding like 15's video

do what they did except with a 12" sub...its 200rms..i will be getting a kenwood amp to power it from my sis...shes selling he stuff to make room for baby stuff.

ne who..a stereo guy said that particluar amp will work fine.

its a jensen nitro sub....i got it for free and i wanted to see if any one knew how to do that.

then if i like it ill do it to my MB quart subs..

Well, maybe i havent paid that close attention to that video, does it say how they did it??? Cause by just seeing the speakers and a big box i have no idea what they have going on inside of it.  Now, for the porting system i have, the transmission line, i have a pdf file of it i could email you to show how mine is (too large a file to post on here), but to describe it, they made a slot about 2 inches wide and the height of my box, this slot is like a puzzle, it goes down one side, across the back to the other side, then back to the side it started on, the starts back a third time and thats it. So its just a slot port that makes a few turns before it ends up in the box, hope that makes sense.

Hers a good article about this design:

Transmission Line: Transmission Line enclosures are a design in which the driver is at one end of the enclosure, with an internal path which consists of a series of bends or curves that lead to a port at the other end of the enclosure. The path length is a fraction of the wavelength at low frequencies. Stuffing the box with either long fiber wool or polyester batting may increase the length of the path. This produces a phase shift in the back waves that reinforces bass at low frequencies. Enclosures must be very large, but low-end response of these systems is legendary among audiophiles. These designs, are tricky since no standardized method for configuring these enclosures exists. One trade off to this design may be a decrease in power handling when compared with other designs, however drivers may be capable of responding their lowest frequency capabilities.

so basically...have the area for the sub...then make a wave in the box right...then the open section on the other end as a rectangle port the same width and length as the channel....Im i on the right track....im thinkin about makeing a scaled down one...and have it cut in half so you can see the insides and have everyones approval....

also i was good post pics of my install that i did to my ma's car...couple american pro 8's...thanks all for the help on that.
