[yAAiYaai]

is there anyone one how to wire a 4 channel amplifier to 2 channel, for a car audio system ?

*** Finally i posted this message here as i couldn't find it after days of surfing ***

I think you had best go to your amp manufacturer's site and look to see if any guidance is given there. I don't believe what you ask is feasible for every four channel amp.

if you really want to run the amp either run the 2 channels or you could bridge the speakers (bridge the f/r speakers together) on either side. go here (http://crutchfield.com) to find info to do this.

I would use two 10K ohm 1/2 Watt resistors to mix each pair of source channels into one input of the 2-channel amp.

Visualize a "Y" with two sources at the top, a resistor in each upper arm, and one input of the 2-channel amp at the bottom. The shields/grounds all are common and no resistive isolation/mixing is needed.

Your biggest problem is deciding which pairs should be mixed. If you already have that down, the rest is cake. http://sysopt.earthweb.com/forum/smile.gif
