Ihave a 600 watt 4 channel amp, i believe rated at about 200 rms i think... I have a 400 rms watt sub hooked up to two channels bridged. So lets say I have 100 rms pushing the 400 watt sub. However, when I turn up the amp to half its maximum, the sub begins to beat violently and doesnt sound good. I just purchased the sub brand new, and I am waiting for my new sub (matches watts of sub) to come in from ebay. I figure too much power to the sub will cause it to beat like that, but can too little do the same thing?

Unless you have a dual 4ohm or dual 8ohm sub, there is no way to hook all 4 channels to that sub. This is your problem.
You need to bridge 2 channels to each voice coil, unless it's a dual 2ohm sub. In this case there is no way.
Right now you are risking the sub and/or the amp b/c of the way it's hook up. You need to take it to soone who can help you better. Take your car to your local car audio shop and have them look at it for you for a small fee. They can get you on your feet as well as make suggestions.
Good Luck!

If it is a powered subwoofer, then having too low rms, forces the sub to magnify the power. So The sub starts beating violently. If its passive then it is defective

Are you using a good ground. I know my friend didn't have a good ground and that caused his subs to be violently.
