I looked around and didn't see a thread like this in the how-to or anywhere so this is the big question... I have a mono amp to a single sub mounted through the cover over the hatch (Zx3) I love my system but there are way too many knobs for me to know what to do with... There is the pre-amp out of the head which i have at +10... then the gain on the amp turned up a little... then a bass boost on the amp and another bass boost by my knees that i use for quick adjusting... I want to get the richest rumble at the highest volume but there are a lot of variables not to mention the subsonic and low pass filters... ive been playing with it but would like some info... for all the talk on how to get an amp up and running - i'm surprised to find very little information on this... Thanks!
