What kind of amps are they? I find it hard to believe that you have a true 1000watt amp driving your door speakers. It may say 1000watt on it but not even the best speakers (ie. Focal, Boston Acoustics, etc) can handle close to that and not blow. Do you know what Ohm load you are running them at and what the amp is rated for at those ohm levels? This makes a huge difference on the strain on your electrical system.
