  • If you haven’t figured this out yet, or if you have this might be useful for someone else, the pop is because you aren’t supplying enough current for the amp. You will want to use a higher voltage or higher current power supply to get the overhead needed.

    As an exercise, you can hook up the power to a car battery and notice that there is no popping. This is because the car battery is basically able to push out as much current as is requested of it.

No public wish lists :(
