what define the classes in a comp these days? i havent been to one since the early 90s. are they still 1-100, 101-250, 251-500, 501 and up??? reason im wondering is that i am planning a new project for the spring and am wanting to be in the 100 w class. i have the sub amps that i plan to use. 2 crossfire 15hc amps rated at 15w x2. so thats 60watts, but they put out 370 underated watts at 1/2 ohm each. doubtful i can find an amp rated at 10w x 4ch for highs. so im going to probably go with another 15hc, punch 40, promos 12, us usa25, or something similar. anyone know or a 4ch thats rated at 40w let me know please. not sure of the vehicle yet have to see what i end up with. figureing crx, astro van, bronco, full size ext cab truck. and the vehicle will determin the subs and quantity of subs.
