this is a follow up to my "special harness" post. I took my caliber to Best Buy this morning to have a Pioneer headunit installed. The tech looked at my stereo and said that it should be no problem as long as the car doesnt have a factory amp installed. I have a base model caliber with not many extras(i dont even have power windows or locks!), so i doubt that i have an amp...can anyone shed more light on this for me
