I started competing in the late 90s up untill anout 06. Ive won as a teenager unfortunately whit my budget on a national field i would get beatout. Last setup up i has was good for a 153 headres which is around a 158 dash and the drivers wheren't of couse in ss 3-4 i was going aginst 4 9918s and 20kw. No way my streetbeat tuned 8kw rd audio alpha 15s could compete but from texas to Georgia everyone swore i had the best highoutput system.Now im bbuilding driver with the same concept. Musical drivers that can be tuned to sound excellent and just raising the crossovers a tad for protection can be easily used like a prosound driver would be for times when i want output tgat sounds much better than pa drivers.
