Take your ohmeter and place the negative wire on the negative speaker post of the amplifer then take the positive wire and touch the amplifier chasis. If you get a 0 ohm reading then you have a common ground amplifier.

Not how its done. You check for continuity between the negative speaker terminals. If you do have continuity you take a piece of heavy gage wire, and tie the two negatives together. No after saying that FIRST contact manufacture of your amp.Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
Thanks

Good catch I was refering to mono block amplifiers. You are correct for two channel amps.

Amp powered up or powered down or doesn't matter?"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it. Differentiation by numbers is for those who do not".--Nelson Pass Pass Labs XA25 | EE Avant Pre | EE Mini Max Supreme DAC | MIT Shotgun S1 | Pangea AC14SE MKII | Legend L600 | BlueSound Node 3 - Tubes add soul!

Any resistance reading or continuity check is done with power off.:cool:
