2) try turning the gain down on the amp, sometimes when the gain is turned up way high, it causes a loud turn off pop.
3)Use a relay to actually turn on the amp, this is more typical when you use more than 2 amps to boost the turn on voltage, but it can atually get rid of the turn off pop.

I agree especially the relay, the audiobahn amps are very prone to those pops
