    I have the basic stats on these amps but i was wondering if someone could tell me their dampening factors. Or if u could suggest whether their dampening factors are over 400. Average used prices would be great too

    Their damping* factors are about 400 or higher.

    When you get into about a couple hundred or higher on an amp's damping factor, it means its output impedance is small enough to be practically irrelevant, and also that the resistance of your speaker cabling is likely to have a greater degrading effect on the overall (amp + speaker cable + connections + whatever else) damping factor than the amp will.

    * Damping in an amplifier suppresses extraneous movement of the loudspeaker cone(s). Dampening, OTOH, suppresses dryness. ;)

    So if i have a good cabinet (aguilar gs210) and really good short 12 gauge cable (i dont know what is a good gauge) i would be ok with 200 DF at 8 ohms, or would i be in danger when i put my amp into 2 0hms

    If the speaker cable is only a couple feet long, then even 16 gauge would work well. Even for a 2-ohm load, if the amp can handle it.
