Hi All,
I bought a 2014 MKX last month.
It has the THX stereo in it and I have to say it sounds horrible. It has a so called sub with and amp but I am not sure where the base is..LOL
I was looking to see if anyone has upgraded there stereo with aftermarket speakers or added a some amps.
I see it is recommend that you do not upgrade the deck because of the navigation system.
Thanks BBryan
