Powerbass ASA 1500.1

I have this amp, and on the side of it is a switch with the word "phase" above it, and the choice is either 0 or 180 degrees. Could someone explain this to me.

Thanks.

I never understood why they put those switches on amps...

you could just wire them backwards (thus, being out of phase) //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

quote 2 only if quote 1 is TRUE. The switch is for reversing the output phase of the amp. Depending on your setup, you may have a more cohesive sound with the subs in-phase or out of phase with the front stage. Give it a click and see.
