my 05 gt has a after market radio in it the guy i bought the car from said he put the radio in his self and gave me the factory one to it says shaker 1000 on it how can i tell if it is the factory radio to my car or if it came with a shaker 500
I'm guessing . A Shaker 1000 would have had an amp. on the right side of the trunk. Maybe run your VIN number and try to find the window sticker showing your options and price. This is what I would do
