Grounding your speakers for better sound: This only requires some spare
light gauge copper wire and soldering equipment. It's for advanced
audiophiles who are not afraid to go into their (dynamic) speakers. Cut
single lengths of wire about the length of your regular speaker wire.
Solder each piece of wire to the positive terminals of each driver
connected to the crossover board inside the speaker. Do the same for
the other speaker. Now combine the free ends of all 4 (or 6) wires, and
connect this to the terminal grounding screw at the back of your amp.

I would only point out that there are certain amplifiers with "floating
outputs" for which this must not be done. One such is the Acoustat TNT
series of amplifiers. A connection to chassis ground is deadly to these
amplifiers, which are otherwise robust. In some other designs, the amplifier
is not harmed, but the connection defeats a part of the design intended to
reduce hum-loop problems.

This prohibition also applies to amplifiers operated in "bridged" mode, as
it will damage them.
