USACi New Classes and Power Ratings for 2007

After watching the dbdrag finals, no one above a street class as a daily driver anyway and I am not about to build a SPL-only vehicle

...I am thinking SB2 and I can crossover dbdrag and run 129.9. I should be able to do both with 2 12s on the back seat.

 
Idea I just came up with...

My idea....

Use the classes set...just with a twist.

if its rated at 1 ohm take the power * .40 like stated.

Amp A is rated at 1200@1ohm its power would be 1200*.40=480 for a class.

If its rated at 2 ohms...Take the percentage of the 4 ohm to 2 ohm jump in power and apply it to a guess on a 1 ohm power...

Amp B is rated at 1000@4ohm 2500@2ohms 1000/2500=40%

so 2500+40%=3500rms guess at 1ohm...

Now take that 3500 and *.40=1400

THIS looks fair to me...

Not really too much different as a 2500@2 would end up being 1375.

 
Thats what im doing...forget all of this power class bullshit, Im just going to run Street Beat where the rules are simple.
i guess ill have some planning to do now //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif plus with as good as Fi did at DbDrag finals i might give them a call
