Yeah.... double that distortion to something you still can't hear....

 

indeed dukk.

I will take the 3db of extra head room over less inaudible levels of THD any day.

 

Well you at least spelt "dissipation" correct. Too bad that's the only piece of intelligence in your post. Good first post btw

 

I'm not certain why you decided to insult me personally, most probably to engross your ego but instead of going off-topic, perhaps with your vast experience here on CanadianCarAudio, you should have explained why my points were false.



I still stand behind my points. When you bridge an amplifier, you allow each channel to operate at a lower impedance, thus technically increasing distortion. Whether this distortion is audible or not, is relative to each individual person (depending on the increase).

At the same time, the amplifier will draw more current than if it was running at a higher impedance, thus making it less efficient and generating more heat.

I would like some clarification on these points, if in fact, they are incorrect.

 

Not really. Distortion is really hard to hear even at 1%...
Distortion varies with frequency and power output. Distortion usually goes way up when nearing the limits of the amp.
So lets say for an amp that’s rated at 100watts it has distortion around 0.02% from 1 watt to 80watts and from 80 to 100 that’s where it goes up to around 1%. Same amp bridged will do 400watts…so from 1 watt to 350 it would be around 0.1%distortion and from 350 to 400 is where it would go up to 1%. What scenario is more likely to have audible distortion in your opinion?

Takes power to make power. I don't see anything wrong with that unless the system is to mutch for the alternator+batt to handle.

 

Nah my ego is already big enough. My response was to say there was no logic/intelligence in your post. Read it again if you like. Pretty clearly written.
And it doesn't need to be explained again does it? Ok then, for the umpteenth time, I don't care how good a persons ears are, they won't be able to hear the distortion. It's a pretty rare case when someone can even hear 5% distortion. Bridging an amp isn't going to get you anywhere near that point.
Heat dissipation? Takes power to make power. Heat is a byproduct.
Consider yourself "clarified".
