Can I/Should I Bridge my power amp?
I use a 6 channel parasound amp (HCA-806) and my main speakers are Totem Rokks. I can bridge four channels to two, but the speakers' impedance are 4 ohms, and as I understand it, bridging channels effectively halves the impedance the amp is seeing, so that with 4 ohm speakers, I'd be asking my amp to drive a 2 ohm load. I'm a little worried about straining the amp and/or feeding too much power to the speakers. The Parasound is a high current amp with a plenty beefy transformer, but I don't want it to melt on me. Please help if you can with advice on whether I can safely bridge my amp.
Thanks.

The amp is rated as follows:
Continuous Power Output:
80 watts RMS x 6, 20 Hz - 20 kHz, 8 ohms, all channels driven
120 watts RMS x 6, 20 Hz - 20 kHz, 4 ohms, all channels driven
Continuous Power Output - Bridged
180 watts RMS, 20 Hz - 20 kHz, 8, each bridged channel, 3+4, 5+6
Current Capacity
30 amperes peak, per channel
The Speakers' specs:
� Impedance: 4 ohms
� Sensitivity: 88 dB/W/m. Maximum SPL 102 dB before dynamic compression.
� Minimum power: 20 watts at 4 ohms
� Maximum power: 80 watts
Thanks.
