Use the specs to figure it out your damn self!


BTW, I really want a pair of 18" avalanches like nobodies business.

[ramos]

New or old ?

[IamDeMan]

New or old ?

old

Did not even know they re-released the name. Have not paid attention to shit in a while. I want the old to use in my attic IB. 4 would be optimal but I would settle for 2. Of course I am in no position to buy them if I did find them though :crap:

[ramos]

Yeah , Scott Atwell ( FI ) bought the ascendant line a few years back. I have a pair special avalanches that were intended for my altima. Just too much work to put the 18's in, so 15's it is lol

My enclosure is ∞ cuft Can't get much bigger lol
Already had to cut out the rear deck and rebuild and weld another in to make the 15's fit the way I wanted them. I figured a way to get the 18's in there, but would lose about 75% of the useable trunk space. Just couldn't do it.

[J31Bro]

I'm just blowin ya shit bromie. I'm an amateur compared to you. You talking about an IB setup?

[ramos]

I figured that. I was trying to get them big bastages in there lol Just too much room lost. and Yup, true IB . There are 2 -13" x 24" vents in the trunk leading outside

[J31Bro]

I've never attempted an IB setup. Maybe one day after I get outa the boom boom stage.
