Hello, relatively new to audio, and have a pair of M3s hooked up via 14ga bare-wire connection to a Sony AVR (over)rated at 90wpc. There is also a 12-inch Sony WM-40 hooked up via RCA.

The problem is, the amp has started going into Protect mode during sudden sound peaks with the amp at 60-70% power. In the past, these volumes have not been a problem for the amp.

This has happened only one other time; when I checked the amp/wire connections, one of the leads had lost most of its wire. Re-trimming, twisting and re-connecting the wire fixed it.

This time, no connections seem to be loose or down to bare wire. All AVR settings are flat.

Any suggestions? I don't want to damage my speakers, and want this setup to work until I step up to an HDMI-capable Marantz receiver.

Thanks!
