MVS 2 Slot Sound Pin Compatability?

I recently bought a two slot. I was wanting to hook it into my candy cab but someone told me that the L/10 pins were + + instead of + - and it would blow the amps out of my candy cab and I would have to either re-wire the speakers for twoslot only use or mod the two slot board it's self. I allready tested it in my SF2 cab and it didn't seem to have any problems takeing it. I'm am a bit more proctective of my candy cab then other cabs, is there any truth to this?

1. There is no amp in your cab... And the speakers should be fine... The sound will just suck....

2. Check this out:

MVS is wired for two Channels.... There are no negative terminals as the Stereo MVS PCB uses the ground instead.

Look around, someone did a stereo/mono switch diagram...

thanks for the info!
