depends on how everything is set up. in MECA if you're above the rear seat you can't be in the street classes, but if you aren't you'd most likely be in street 2. MECA decides based on the in line fusing closest to the amp and you cone area, you take your fusing, multiply it by 10 and then add your cone area. Street 2 is the 1000-2000 class, but to be in a lower class a lot of competitors put in smaller fusing, then roll their bass knob or volume up until it pops during their burp, so really, you could compete in Street 1 if you want to buy a couple fuses before hand.
now USACi has the Street Beat classes which are a 30 sec average on music and this is determined by cone area on a points system, I believe you'd be in SB2 with a 15 and then there are battery limitation and such. Their burp classes are decided based on power, a lot of people run high cone area, low power or will run at 4 ohms or something just to keep their class down. The classes are 0-600, 600-1800, and 1800-up. Now I may be wrong on some of these classes and someone may come and correct me but this will give you a general idea.
