nice vid. that's not infinite baffle.

better off with a ported box.

also, i would not hook up all those different types of batteries together like that.

The ages and cca's match on the batteries

That's the only reason I use them together.
My buddy's snap on battery analyzer gave them the same score /1000

I haven't beautied anything up either had to have surgery 1 day after I got it to "sound"
Now I'm healing and waitin for above zero temps to work in

I appreciate your opinions
Thanks, keep emm commin

Popular theory suggests that once the enclosure volume exceeds 3x Vas it has decreasing effect on the operation of the driver but full IB operation is closer to 10x Vas.

Vas = volume of air having the same acoustic compliance as the driver suspension.

IB is like the listening area being inside the box, and outside factors aren't wanted.

A true IB would be like sitting inside a giant sealed box that is on your front lawn so walling off a trunk is not an IB and you can never have a true IB from a trunk. You have a weird 6th order bandpass because the cabin and trunk aren't completely sealed. I'm having a hard time calling the seams in the doors & small holes everywhere ports but they aren't sealed completely so that's what they act as. Open the trunk and you still don't have a true IB because the sealed portion isn't completely sealed and it becomes a horrible ported box. A normal ported box inside a trunk is still a sixth order in the end because the cabin isn't sealed. The only way to have a true IB in a car is to mount the subs on the roof and that's extra stupid.

I hear ya man it's weird but for some reason loud as hell too
It basically has problems transitioning notes but doesnt sound bad
Just looking for options

As for the seals in the door leaking that's no lie but it performs better with both windows open like 1/3 Shouldn't spl go up with them up? WTF
