Hello My Car: Lincoln 1998 town car with jbl system Problem: I put i new speakers and they have sound but no bass at all. The bass is going to an old sub woofer. I unplugged it because it sounds horrible and now i have no bass from the car. Please help. I tried to reverse the polarity of the speaker connection. Do i need a new head unit or what?http://www.caraudiotalk.com/audio-forum/images/smilies/mellow.gif
