I have a 4 ohm Bill Fitzmaurice cab, which I am powering with a Carvin HD1800 amp, with just one channel. The other channel is inactive. Seems fine but the fan is coming on and the amp seems to run a little hot. I'm not really pushing the amp too hard (volume is at noon) so I'm wondering... Would it be easier on the amp to run it bridged into the cab? At 4 ohms stereo, one side of the Carvin's 600 watts is a perfect match for the BFM cab (Omni 212, rated 600 watts with two 300 watt speakers). At 4 ohms bridged, the Carvin puts out 1800 watts I guess I'm mainly trying to avoid fan noise if possible, and not run the amp any harder than I need to. (And not blow any speakers ) Comments?
