i use to compete in iasca 501-1000watts pro with 16 12's (164.4db)
i know the rules have change a lot sence then,
want to do it again and i am not offically in the industry any more so i would not have to be in the pro class, trying to find out what type of system to build to compete in.

I go way back to the late 80's - you all refer to Big Mike - I remember him when he had his first job in car audio, & when manufactures built real AMPS!
