    Dumb question

    If bridging an amp makes more power (in watts) wouldn't the output be louder?

    example 60X4@4ohms RMS or 170X2@4ohms RMS

    Just a bit confused because not getting the volume that I figured I would be getting.

    Well yes more watts typically means louder. Explain exactly what you have going on

    Re: Dumb question

    I went from a Pac Soem4 to a phoenix gold R500.4 amp in 4 channel mode to factory speakers to an Audiocontrol LC2I to the Phoenix Gold Amp bridged to Arc Audio Arc 6.2 speakers. Not sure what is going on when I set it up using a -10db 1khz test tone and a dmm per Audiocontrol's instructions the gain on the amp and the sound was low. When I turned down the LC2I and the gains up on the amp as a test it sounded a little louder. I set it both ways when bridged to 150 watts so I am a bit confused. I figured 150 watts would sound the same either way it is set.

    Re: Dumb question

    Generally when you bridge two channels the combined output power is just the sum of the two. It's still using the same components so it's unlikely it can create MORE power.

    i.e. 60w x 2 bridged would produce 120w x 1 (not 170w).

    When you double the power to a driver the output should increase by 3dB. The problem is you are comparing 2 different drivers too, if the efficiency of the factory drivers is higher than the Arc Audios you may not get any increase in output.

    Re: Dumb question

    Ok thanks everyone. That's what I figured Vaiboy. I will say this the Arc Audio speakers are cleaner and crisper sounding.
