Running stereo vs. bridged mono

 

Anonymous
 
i heard that if you bridge a 2 channel amp you can gain like 1-3dB over running them in stereo.

and that 10dB is considered twice as loud.

is either of this true?

Running a bridged four ohm mono load is the same as running a two channel amp in stereo at two ohms.

well on most amps you get another 3rd of the watts added on when you bridge the amp at 2ohms thats what i have read

ok say you have a 1 ohm stable stereo 2 chan amp..when u bridge it, it's stable down to 2 ohms and has the power of both channels added together when they run at 1 ohm

does that make sense?

and yes, 10 dB is double the sound

Yes your speaker load would be two ohms, however when you bridged the amp you lowered it's load to two ohms, so hooked up now in parallel you have a one ohm load, your amp had better be rated for this load.
