I was wondering, what is the sound quality like with the 15"??? Everyone is always talking about the 12", but if the 15" still have decent/good SQ i would go with 2 of those instead of the 12's.
Image dynamics says to use 1-1.75 cubic feet. I figure since my amp puts out a little less rms then recommended, even though it is underated, i will use a 1.9 cubic foot sealed.
ok there is only one problem. Your amp is not 1 ohm stable and you dont get nearly enough power at 4ohms. those are dual 4ohm subs run mono to a mono amp you can only get a 4ohm or a 1ohm load.
my bad I dont know what I was thinking. I knew that. I told you its been a long day. well I would think that your amp pushing 2-dual 2ohm 15's would do just fine in a slightly larger sealed or larger slot ported as well.
