On Off pop annoying, odd mix of system.

Hmm, crappy title, sorry.

I have a sub being run off of a car amplifier and battery and I also send 12volts from the battery, along with a 555 circuit to invert +12volts to -12volts(http://sound.westhost.com/project95.htm),to my crossover.
I have 1 switch to switch the power on and off for the inverter/crossover and at the same time it feeds the 12volts remote switch to switch on the car amp. Confusing, Uh?

When I switch on, the main speakers thud, (even with volume right down), and when I turn off, the sub clicks?

Where's the Nasty, please?

You need one more switch, so that you can turn on the inverter, wait 5 seconds then turn on the amps. Turn-off is the reverse turn-off the amps, wait then turn off the inverter.

I was hoping to did it with just one switch. But 2 will do.
