Hey everyone, so when I got my towncar it had 70,000 and now it s around 143,000. Well when I got it the subwoofer was broken, there was no bass at all. Well since then, i ve taken the subwoofer from an Infiniti FX35 and now I get bass at lower volumes but when the volume gets about halfway up it cuts out. The speakers still put out mids and highs but the subwoofer cuts completely out. I don t know the specs for the Infiniti sub but I know they re not the same as the original from the towncar. Should I get a new subwoofer? Or is it my amp? Can someone point me in the right direction. Thank you!
