I have a amc 2100 hooked to two Infinity perfect 12s. The amp clips off with out warning. I have tried hooking them in 2 ohm and 8 ohm loads ,,,bridged mono and in stereo. The amp still turns off and has to be turned off to reset it. The gain is about 2/3rds. the way up. The woofers are in two, 1 cubic foot sealed enclosures. When playing them I start to turn them up loud and they sound awsome then a big bass note will come along and the amp will clip. Usually a woofer will distort a little so you know to turn it down,,, but it gives no warning. Please help me,,,,do I need more power???

Sounds like the amps power supply ie. transformer doesn't have enough grunt for your application.........You may need a beefier amp. IMHO

For $400 you could build a real beefy 200+ wpc amplifier that could rival alot of commercial amps of higher cost. Here is one that I am currently constructing...............Check it out!

I would rather buy an amplifier, than to build one. Wondering if pro audio amplifiers are a better choice than a home power amplifier. Such as a BEHRINGER EP1500.

Try to find something with at least 200 wpc and stable with a 4 ohm load. The AMC as near as I can tell by the spec sheet never stated anything about its stability with anything less than 8 ohm. Those Infinity drivers need alot of power to really make them sing.

How important is the damping factor of an amplifier. Is a 300 watt per channel with a 3000 damping factor better than a 400 watt amp with a 100 damping factor??? Can you tell the difference??? What if the damping factor not listed in the specs does it really matter???
