Im getting 1x12 Earthquake Subzero and powering it with a Earthquake PHD2 amp(2000watts/1000rms)(its not on the EQ amp webpage). I really dont know what kind of box to put it in. Its going to be put in a demo vehicle (to advertise earthquake products for local dealer)The dealer wants to put it in a prebuilt box from on the the companies he sells. It needs to be loud(kind of hard not to be with a 2000watt sub/amp) but it also needs to sound really good. Any suggestions on size, port or sealed? I believe manufacture suggests a 1.9 cu ft for a ported bix but im not sure. Thanx
