[06sublade]

Hello I was woundering if any one could help me come up with the dimensions for four sound qubed hdc 3 18s in a 2006 Chevy suburban.I blew one of my 15s and it's time for a change.Any help would be greatly appreciated. Thanks in advance.Kevin.

for anyone to help, you need to post your maximum dimensions and what kind of power you're running them on. probably more stuff. i'm no designer but thats some of the stuff the people that do need. probably more info.

I'm currently running four Diamond audio D 9s and two soundqubed 3500s.I'll try and figure out how to upload pics.And get back with max dimensions.

Not sure you will benefit going from 2 15"s to one 18", were those cheap 15s?

Hey joe. He said for four(4) eighteens

The maximum demensions are 49" wide.44"long and my old enclosure is 24"inches tall.But I could go taller just kept it below the window before.Still can't figure out how to upload pics.

Maybe a wall would probably give better results depending on a number of factors, the subs up box would need to be a little above 26" and roof deadening will be necessary, and that 44" would not include port clearance so some more depth would be needed for it.

Thanks Joe I'd like to keep the subs up.I have enough room to go taller and longer.My current enclosure is subs up with the ports up also.

How much depth above 44 you have? Also you will have significant roof flex firing everything up which will likely translate in lost output.
