dont no if anybody said this yet but the orion 2500d can run daily @ .5 without a problem at all.. Ive run 2 at .5 and they never had a problem, just got warm a lil quicker if ur beating the piss out of it all day
the 15 is $400 and the 18 is $425 - I was just wondering (The subs are TRUE dual 1,2, or 4) so its .05 or 1 ohm - so im pretty sure im gonna get an 18 MT with dual 1 coils - and yes i know how to wire it.
