hi ,,, please help me out i have a pioneer deh-4300ub head in my 2000 honda civic and a alphine mrx-v60 5channel amp fixed in my car,,, there are 2 preout in my head unit ,,,, one of the preoutput is connected to a1- 2 channel input in my amp and the other rca is connected to the rca input in the amp for subwoofer,,, and my 3-4 channel is not working even when i plug the the other rca output in that instead of connecting to the sub input. i heard that there is a setting that will allow 4channel to run with both the rca outputs connecting the 4 channel and avoiding the sub,,,, how do i find the setting options ?? somebody please help me
