Keep the relay disconnected for x seconds after power-on, giving the amplifier time to settle, then close the relay to connect the speaker. This alone would eliminate your pop at power-on. You can also disconnect the speaker when the power is turned off (but before the amplifier power supply drops too low to work) to eliminate a thump at turn-off.

These different turn on/off intervals may cause an audible "pop" or "thump" when turning the system on or off. For example, if the amplifier in a system turns on before a crossover, the crossover may send a small transient signal to the amplifier. Because the amplifier is already on, it amplifies the transient signal causing the turn-on noise.
