Hello Jorge016,

Hope you are well. Harman/Kardon receivers have a lot of current, but yours seems a little small to try 2 M2s on one channel. Does the AVR 130 have pre amp outputs to add on a beefier center channel amplifier? Your smaller receiver may overheat, or worse clip the signal causing damage to your speakers.

The AVR 630 that I have is rated at 75 watt/channel into 7 channels 20Hz to 20kHz, and 90 watt/channel in stereo 20Hz to 20kHz. So, that is 30 more available watts in surround mode.

Personally I don't think it is worth the risk of damage to your system.

Later,
