Car Stereos: amplifier, channel amplifier, amps

Question
just want to know how can i brigde a 2-channel amplifier?

Answer
Charlie, most amps tell you how to bridge the two channels.  Of all the ones that I have wired, most of them require using the positive of one channel and the negative of the other channel to connect to the speakers.  Otherwise, find out what it takes to bridge yours and do that.  Hope this helps, Scott
