Well, I recently blow my subs (realizing that they only need 300watts) and well my amp has a power of 1000watts. I have two 12" Comp Kicker subs. So I'm not exactly how to turn down the amp to the proper wattage to get it so I don't blow my subs again. By the way, the subs are being replaced free of cost 
Thanks for your help.
