    Default SDA's and a common ground amp

    Good morning polk forum. I have a pair of Polk SDA's and I have 2 Adcom GFA 1 amps. I think the amps have a common ground. I would like to use them for my SDA's. Could I use one as a left amp and the other as the right using left for tweeters and right for drivers? Would that eliminate the common ground? Thanks in advance for any input.

    If you plan to use one amp for the lows and the other for the high's then be sure to remove the "jumpers" from the speaker terminals.

    Yes. I guess after some research the Adcom GFA 1 is a common ground amp and I can use it with the SDA's?
