Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

jon_5912, Yes, current will double when you double voltage, but you stated that current CAPABILITY (meaning max current) will be better. Current capability of AHB2 in bridged mode will be still 29A.

Assuming that you meant current (and not current capability) at given volume, it should state "at given volume knob position".  At given volume (meaning loudness) bridged and unbridged configuration currents will be the same.

Max current will double.  If an amp can double the voltage into a load by bridging then the current capability also doubles.  I'm not sure what the max current rating really means.  29 amps into 8 ohms requires 232 volts.  I'm pretty sure that isn't possible.  Maybe it's theoretical short circuit current or something.  

Maximum current won't double.  (It will be still 29A).    Maximum current is an absolute maximum that amplifier can deliver.  This specification shows amplifier's ability to drive difficult low impedance loads.  It says that when 4 ohm speaker's impedance drops to 1 ohm amp can deliver 29V peak.

Also, I'm not sure where specification 480W/4ohm came from.  My manual (version G), as well as their website, shows 480W/6ohm bridged and 130W/6ohm unbridged.  480W is not that far from theoretical 530W for ideal voltage source.

The maximum current that can be delivered into 8 ohms or any other load will double when the voltage doubles.  I obviously wasn't talking about the 29 amp "Maximum Audio Output Current" as specified by the benchmark website.  We were discussing current capability into varying typical speaker loads.  The maximum continuous current capability into 8, 4, whatever loads will increase when an amp is bridged.  

The maximum continuous current capability into 8, 4, whatever loads will increase when an amp is bridged.  

Agreed.  The only confusion is word "capability".  IMHO it should be:

The continuous current into 8, 4, whatever loads will increase when an amp is bridged.
