im looking to upgrade my current system in the near future which is 4 18" mj's which would be louder all off around 4000 to 4500 watts will be going into a 2002 escalade

4 18" bl's box will be right at 20 cubes so 5 cubes for each sub

4 21" IA DP's box will be right at 24 cubes so 6 cubes for each sub...i heard they like around 8 cubes each so will they still be loud at 6 cubes?

4 18" HDC's box will be right at 20 cubes 5 cubes for each sub

by the way no walls only subs facing up with port facing hatch

4 IA 18s in 24 cubes (waste to put 21s in 6cubes, might as well do 18s)

I would go with IA 18"s in 24 Cubes or FI BTL's in 24 Cubes not BL's.. Just my 2 cents..

EDIT: never mind I just saw your power if you had 6 to 8k then BTLs with 4k BLs would be good.

I agree on the BL's and DP's.

I love my 12" HDC's, dont know about 18's tho. But Im sure thier just as good. Also with the HDC's Im sure 2 18's would do the job. IMO less space is always a good thing.

18" HDC's can do very well in 5 cubes each, although a little more power wouldn't hurt...

Get some 18" Nightshades and call it a day...they will love 4-5 cubes each.

death penalties are rated @ 1500rms, on 1000rms i would get the death rows, i am surprised no one has mentioned this. death rows compare to the bl's, death penalties is a whole new ball game.

if you want 21's, they are coming out with 21" death rows soon. but yeah with that power, dont get the DP's.
