my system consists of a head unit(of course) running to a 6 channel crossover, then to 2, 5 channel Alpine MRD-f752 class T amps. (both measure at about 110RMS x 4 + 400RMS, thats for each one) I am then running 2 sets of 6 1/2" components, a seperate set of tweets on the dash, 2 audiobahn 8" 200 watt RMS subs in a .5 cubic foot(wired at 4 ohms), sealed inclosure between the driver and pass. and in the rear I have 2, 12" PG, XR dual 2 ohm 350RMS, wired at 4 ohm. I was wondering what class I would be in with everything running, and what class I would be in if I disconnected my 8's?
thanks

Well.. if he were using the 8's during the competition it would put him in the Monster class because they are in front of the b pillar [img]graemlins/thumb.gif[/img]

8" subs are not counted but if you add more just to circumvent the rules you will be DQ'd!
