anyone know what cu it should be? 1.25 says diamond audio in a ported box, idk what its supposed to be tuned to, or if that is a good size for the box. any info would be greatly appreciated.
Are you running aftermarket HU/front speakers? If so, tear all the Mach crap out and build your box the way you want. With the 460 amp rack/speaker housing, 2 12s is going to be very hard...
