So I just bought a power attenuator for $130. It does its job, but is very noisy. I don't really know very much at all about them, but if I were to shield the inside with copper foil, would that reduce noise? The make is Weber. I don't know if they're any good or not. I also had it sitting directly on top of my amp because my speaker cable is not long enough. Could that cause alot of the noise? Anyone?

Attenuators themselves make almost no noise at all. If you're getting more noise it's probably because you're turning the amp up louder than you would without the attenuator.

That does seem unusual. Noise is normally induced into high impedance circuits with gain. An attenuator is a low impedance circuit with no (actually negative) gain. I doubt that shielding would do anything.
