Hi All:
Since I can not find anybody in China who is trustworth to help me tune my system so I decided to give my self a try...
As topic, I am now using the Alpine W502E as my head unit and TG amp+stroker sub!! The problem is in the head unit there is a subwoofer volume +15 max...when I turn it to zero, no sound from sub at all... so should I adjust from amp or just turn the volume from head unit to the max at all times???

Are you using an LPL? Couple of different options to try,How many preouts do you have? Are you using rear speakers? Any other amps in the system? Your post is kinda vague other than what you are using as a sub stage. tell us more and we can help you better. 

screw car audio, I'd rather go fast....errr, wait a minute.
