my subs are dual 2ohm + 2ohm but they are bridged to the amp at 4 ohms

That's impossible. You could only provide a .5, 2 or 8 ohm impedance to your amplifier bridged with two 2 ohm DVC subs. Again, how are they wired?

Steven Kephart is right. I've got an odd feeling you might be giving your amp a .5 ohm load, and that isn't good in your situation.

That's my opinion. Take it, leave it, or correct me.

With a .5 ohm load wouldnt that cause the amp to fail or go into protection.

This is exactly what I was thinking the minute I read the thread. You have sent the amplifier into thermal protection by asking it to drive a load lower than what it was designed to be able to safely and properly operate at. While the amp may indeed operate at this level for a finite period of time, the heat signature of the amp is going to go through the roof. Your best as safest bet to use these subs with this amp is to wire the two subs in a all series circuit and have a 8 ohm load running to the bridged terminals of the amp. Here is the proper way to wire these subs to this amp.

Top Secret, I can tell you but then my wife will kill me.

Oh, I see now. You have 2 amps. Sorry, I missed that.

When you are saying price is not a factor are you serious? Cause I can name a lot of subs that are pretty expense, but sound a lot better. Or do you want something in that general range?

That's my opinion. Take it, leave it, or correct me.

I'll say it again and maybe you'll listen this time: your amps are clipping. Either your gains are too high or the input to the amps is clipped or both.
