Rat Shack has 'em if you don't have any other source. You can prolly find
a socket for one there too, or just cut both ends off an extension cord
leaving a few inches of wire on each and solder directly to the relay's
lugs.

That one is only good for 10 amps. My amp can draw 11 so I'm really
looking for one rated for 15-20 amps.

OK.

Above 10 amps or so, it's call a "contactor."

You can get then at an electrical supply house (with either 24 volte or 120
volt coil). If you are cheap, you can "salvage" them from a microwave oven
or a central A/C. It's kinda fun to take apart a dead microwave oven.
You get a transformer suitable for making your own electric chair among
other things. The magnets are a source of some amusement also.

"Contactors" have either screws connections or a "spade" male leads. You
can get the connectors at R/S. Put the whole thing in a box to keep your
cat from getting fried.

Since you only need 11 amps you can consider getting a two pole relay from
R/S with each pole rated for 10 amps. Wire the poles in parallel and you
have a 20 amp relay.
