Why would you want or even need the balance function? I cannot think when you would have the left side turned up higher than the right side?
Wouldn't just font and back fader be sufficient? What advantage is there to be able to balance as well. I think the only time ive ever used the balance is to check if a speaker is blown without having to put my ear against it.
Probably an obvious question, but Im pretty new to car audio.
Well, if you WERE to use a 2 channel amp to power 4 "channels" per say(Front Right, Front Left, Rear Right, Rear Left), you would want the balance option as opposed to the fader. Reason being is that basically in stereo recordings you will have sounds that play between the left and right channel and also independently from one another. Not having a left and right channel would really screw up your imaging (plays a big part in sound quality) and your music would not sound remotely how it's supposed to. Another reason you wouldn't want to do this is because, even if you hooked it up for left and right instead of front and back channels, your front stage and rear fill would put out the same volume. Ideally, you want your front speakers to be the loudest and your rear speakers to provide a hardly noticeable ambient fill. If you already have a 2 channel amp that you want to use, just power your rear speakers off of your radio and pump the extra juice from your amplifier to your front speakers. Make sure to tune your setup carefully to avoid overdriving your speakers and to avoid clipping from the internal amp on your head unit for your rear speakers.
