[QUOTE="tcguy85, post: 4346456, member: 574289"] nope i am not crazy. i have 200 on each mid and 100 on each tweeter from a DD S4, and i still see the clip light blink every so often. this is the reason why its good and ok to run such "crazy" amounts of power: Music is not constant in its peak amplitude. The ratio of average power to peak power is in the order of 10-20dB. (10dB = 10 times power and 20dB = 100 times power). [B]I would imagine that modern rock and roll/rap music the value is closer to 10dB. This means that with typical music the average power when using a 200w/ch amplifier is in the order of 20 watts per channel with the peaks rising to 200 watts. Anything higher than the 20 watt average will most certainly push the amplifier into clipping.[/B] With this scenario the tweeter in a typical bi-amplified system or one with passive crossovers will receive about 10-15% of the power.
