2008 MKZ THX Aftermarket Sub Wiring


Junior Member
Thread starter #1
I am looking for a little extra oomph from my 08 MKZ's stereo system. The upgraded THX system is no slouch but, at higher volume, the bass distortion from the 6x9s is awful! I am looking to run a sub and amp in the car but don't want to ruin the look of the dash nor lose the navigation system, etc. Does anybody have any experience running a sub and amp with the original THX radio?
