    MW6509 x 4 ? Don't believe it's compatible.

    You are correct, they are four 6509.

    So how can I use them with a non common ground amplifier?

    Sorry I'm a noob.

    You cannot, unless you do not use the interconnect cable. Both blades are active and your amp sees a short makes loud noises or lets out the magic smoke. IF The cable is used.

    Looks like I have to contact my amp manufacture to see if I can strap the grounds together right?

    Yes

    Another thing to check is resistance/ohms with multimeter between negative binding posts. Remove the speaker eirye from binding posts.
    Too much and it affects negatively.
    I'm sorry I do not remember if it's resistance or ohms, so hopefully someone will chime in.

    Which Amp?

    A single NAD 2200 in stereo mode is common ground. LINK

    I've used a NAD 2600A (largely the same amp) with no problems on my SDA 2B, prior to having my Dreadnaught.

    Edit: That thread isn't exactly confidence inspiring to the max, but I feel it shows that you should be safe with that amp and your speakers. Anyone else care to weigh in?
