    How to bridge this amplifier

    Hi people I got a two channel amplifier but I couldnīt get the specifications so I donīt know how to bridge it. Iīm sure I can bridge it because it is write in the amp. It has this configuration...

    ......." In the image box at the bottom"........

    Does it mean that I need to connect + from L-CH and + from R-CH to bridge it up? The + from the R-CH is now transforming in a - ? This is really confuseĄ Could someone explain me whatīs going on here...

    Also I know that all of you know what happen...
    I trying to bridge it to mono for a 4 ohmn speaker, the low in impedance from 4 to 2 ohmn in a bridge amp will kill my 4 ohmn speaker or not ?

    Connect + from one side and - from the other. The resistance (ohm load) of your speakers stays at 4 ohms. It's the amp that is now seeing 2 ohms per channel when it's bridged. As long as the speaker can handle the increased power you should be okay.

    Replace the "bridged" with your speaker.

    Some amps bridge the channels differently. Some use the + from one channel and the - from the other channel. Others use both + and one essential becomes the -, like your amp.

    The Positive from the Rch becomes negative. So your second statement is correct according to that diagram. That was on the amp right?
