Plenty of guys likely to show up with 5K in all cone areas of that class. 1200W rated amps are a bad move in our local orgs since it's over each power limit in amateur and you can only use 2 amps in stock classChances are ill have 4 15's before I even get a 2nd DD9512... and chances are I wont run more than 2.4K to all 4 (for the first season then Im getting a 5.0K) and no... It works off woofer size but not always. Depending on cone area is dependant on what class you are and each class has a power rating... I'd be in a class that is limited to 5k which NOBODY is within. Derek is running over 10k, so is keith so is mike anda few others I'd basically have nobody in my class lol.
