I have the Shaker 500 in my Stang, but my Stang is a 2007. I changed stock speakers to Shelby GT speakers all around and added a JL 10" subwwoofer in the trunk. The Shelby speakers which are "Kicker" speakers in the front are 8" in the doors and long throw 6X8 in the rear. The only issue I have had is: The Shaker 500 is a CD changer also, holding 6 CDs at a time. And I have not been able to find a Double Din CD player that holds multiple CDs, that also has the other features that the Shaker 500 has. That's why it's still in my car. There are many players out there but none I've seen that hold more than just one CD at a time. Other than that, I have not found anything wrong at all with the Shaker 500.
