So I put a new radio in my truck over the weekend. I have the infinity system in it. It sounds good, but I want to tweak the audio settings.. I was wondering if anyone knew what setting I should put the sub at and the amp settings (if any) at.

 

Depends on how you want it to sound.. Play around with it a little till you find the setting that your own ear likes.

 

Here is a very easy "beginner" guide on how to adjust your stereo.

This is just a basic how-to... there are many how-to's out there that vary in complexity. It really depends on exactly what you have in your truck, and your specific taste in how music sounds. So do some searching for a method that works for you, as for the Subwoofer (I'm assuming you have from your post), you'll want to check out the "step 2" in the how-to I posted above. It give you a basic breakdown.
