Looking for DPDT rated for use with high current

[itsGiusto]

I have a few cabs I want to add a DPDT to in order to aid the switching of speakers. Can anyone recommend a DPDT that should be able to handle the current?

For one of my amps, the current should be pretty damn large, I think. It's a 50w plexi, which I think means it can reach 100w or maybe even 150w output. If

p = i^2 * r

and r can be as low as 4 ohm, then the current could be as high as 7A. Any recommendations?

Any 20A/125v AC switch will work great. Just do not switch it when under load, and the contacts will last forever.

Does "under load" mean "while the filter caps are charged (whether amp is on or off)" or "while the amp is producing meaningful audible signal through the speaker other than quiescent hum" or something different?

When the amp is powered on.
