[QUOTE="Wonderbread, post: 1364178, member: 541455"] I'm sorry, the "normal" position? There is no "normal" position, unless things have changed drastically in the last year. Gain is measured in milivolts. You have to match your amplifier gain to the headunit's preout voltage. First things first, grab yourself a screwdriver and head back there. Turn your head unit up to basically the loudest you'll ever listen to your music. Turn your gain ALL THE WAY down (usually left). Now slowly start to increase the gain until you get to the point where you can hear distortion in your subwoofer. Now back it off a hair. Depending on your preout voltage, you'll probably be above halfway. Also check your lowpass/hipass. Make sure it's set to lowpass and have that set to around oh... 80hz. You might also have a "bass boost" setting. Try and leave that as low as possible, but there's no real harm in increasing it a hair to get the sound you want. At the headunit you should also make sure your lowpass and subwoofer settings are set properly (if applicable). [/QUOTE]
