I just want an amp that will do 500 or 600 watts x2 at 4 ohm's in stereo. That's a BEAST You were the one talking about the Zapco 1000.4, it does 500 x 2 @4ohm! There's a few others I have found, the Sundown 200.4 take's the cake at 615 watts. Now I have to change my awnser, after reading the ZED newsletter. Dreadnought: The name is in recognition of the First World War British battleships. This amplifier is truly a Dreadnought. Rated at 225w x 4 at 4 ohm and 400w x 4 at 2 ohms it is a true power house in the world of 4 channel amplifiers. Bridged power into is 450w x 2 into 8 ohm and 800w x 2 into 4 ohm. This should satisfy the power cravings from sub duty to tweeters! The feature sets are identical to those shown above for Draconia. The foot print is identical to Leviathan. That amp is just going to be flat nuts.
