I have an Earthquake ph500.1 aplifier and I am having a hard time finding specs on it as I assumme it is quite old.

My best guess is that it is 500RMS x 1 @4ohms.

Any input would be greatly appreciated.

No one is framilar with Earthquake's rating system?

It must have been a very rare amplifier.
