Concert Radio ID

[gnjim]

Can anyone help me how to tell a concert sound radio from a non concert sound. Would like to install it and have one here with an equalizer but I don't know how to tell if what I got is for Concert Sound. Also is there any difference between the years? Thanks for any help

I believe the concert sound option, adds 2 speakers to the doors, im not sure if the head unit is any diffrent than a normal head unit with an EQ.
