How to bridge this amplifier

**Williams16** · 12-13-2006, 04:45 PM

Hi people I got a two channel amplifier but I couldn´t get the specifications so I don´t know how to bridge it. I´m 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 confuse¡ Could someone explain me what´s 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.

So what is the real way

positive from LCH and negative from RCH or

positive from LCH and positive from RCH and the positive of the RCH will change to negative when bridged...

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