Not an audio guy, extremely noob 4channel amp question.

I've searched for a while and came up empty, I'm not an audio guy so it's like a whole different world to me.

What I need to know is when I get ready to connect the 8 speaker wires to the amp, it looks like this..

1chan +/1chan - 2chan+/2chan -
3chan +/3chan - 4chan+/4chan -


Does it matter which speaker goes to which channel?

Thanks!

Lee

Not inherently, but you want to make sure that the speakers being hooked up correspond with the correct RCA wires off of the radio. Otherwise, you may get oddly staged sound, with ***-backwards balance and fade adjustments.

No, just make sure you hook up the + and - wires between the amp and speakers right and you should be fine. Also make sure the power rating for each speaker can handle the power from each channel.

Yes it matters, or your fade and balance adjustments won't work. Or the front of the car might end up "left" and the back "right", which as Phantom420 suggests will sound weird.

Or rather, it doesn't really matter which amp channel you use for each speaker, but you definitely want to make sure the left front signal goes to the left front speaker, the right rear signal goes to the right rear speaker, etc. How you connect the head unit to the amp will determine which amp channel (1, 2, 3, 4) maps to which signal (LF, RF, LR, RR).

And you must get the polarity (+ and -) right for all four speakers, too, or they will cancel each other out and sound weird.

Well, it does if he's using it for a front/rear setup, but if they're all in the back then the fade doesn't necessarily matter, which he didn't say what his setup is going to be.

exactly, and nonetheless, i'd try each speaker out one at a time to set up my fade and balance settings.

most likely
chan 1 is fl
chan 2 is fr
chan 3 is rl
chan 4 is rr

alot of amps will let you adjust settings for two channels at once, so its important that you get those two matched so you can adjust front and rear seperatly, you don't want the left side of the car being louder than the right. however you may want the rear to be louder than the front, if you have large subs or something in the back
