Sound System Upgrade???

[PHATCAT67]

Can You Upgrade The 04 Aviator Navigation System To Thx????

My Sound System Sucks!!!! Almost No Power From The Sub, And The Speakers Are Kinda Weak!!!

Any Tips???

Replace all of your interiors, get good subs (Rockford Fosgate, JL Audio) And it should sound good. If you don't have the navi, switch the headunit up too.
