I had Best Buy Jackson, MS install a Pioneer head unit a Polk Audio 12" Sub and Polk Audio Amp. My question is why does my sub only respond if my headunit is on normal or faded to the rear. If i fade to the front I can tell that my bass is still very heavily coming from my door speakers. And its causing them to blow. I have installed subs myself before and never had the doors getting the same amount of bass as the sub even if the head unit has only a bass control like mine does and not a sub control....

I am going to put bass blockers on my doors as soon as i finish installing the front 2 door speakers but should I look at getting a new head unit or adjusting the gain on my amp so the sub is pushing? Or is there a setting my Pioneer headunit I can adjust to not recieve as must bass in the doors?

Help cause I'm stumped as why my doors got so much bass.

The reason the sub only works in the center or rear fade position is most likely because the RCA cables are attached to the rear preouts.  Depending on the model of your Pioneer (and MOST of them have this) you can switch the preout to SW instead of rear and then it becomes a non fading preout (meaning that it plays no matter of the position of the fader) and adds a sub level control into the audio controls.  I would suggest looking for this option in the menu.  It usually presents itself as "Preout:Rear" and that is where you would switch it to "PreoutW".   At that point you should find an option for sub level control in your audio controls and can adjust it independently of your bass control.  I like to lower the sub level completely and then adjust the bass on the regular speakers and then add the sub in and set its levels.
