Amplifier sub out to Line input

[uxri]

Hi guys,

i have a tube amp of 20W which have a sub-ou. Can i use the output to connect into a Line input of a 60W amp ? Making the 20w amp as a pre-amp ?
Really appreciates your assistance.
Thanks

No, unfortunately you can't do that.
(Because you would only be sending the lowest frequencies to the 60W amp).
Try it and you might see what I mean (if your normal speakers can reproduce such LF).
