Not if the speaker wires are shorted as they sometimes are if a sharp
tool was not used to cut the wire. Shorted speaker wires can destroy an
amplifier in short order.

Connecting one lead from a tone generator to one speaker wire and a the
other lead to a ground will create a much stronger and recognizable
signal than music. If the signal is too strong disconnect the ground
connection.

Using the tone generator is much easier for you and safer for your amp.
