hi friends... I sharing to what is bridging an amplifier????
Overcoming combination of the two amplifier channels in a channel for more power. For example. 2-channel amplifier offers 75 watts RMS per channel at 4 ohms and can deliver up to 200 watts RMS at 4 ohms in the channel when the bridge, it would be nice to drive a sub woofer, there is a formula to determine how much energy get to the bridge platform channel amplifier - each amp is different. 4-channel amplifier capable of a bridge that can be easily used in different situations and systems - most of them. Another example is the use of 4-channel amplifier to control the left and right is two channels, while southward, the other two channels of the bridge together, so you do not have to buy a separate sub amp.
