I bought the Pioneer A6966R and they sounded like absolute garbage.
But they were absolute garbage, i installed only the right side and the left oem speaker sounded better then the right one did, so I just swapped them for jbl.
I did the same thing when I installed the Pioneers. After I had swapped one speaker out, I had one Pioneer and one OEM in the front doors. The Pioneer was obviously clearer, louder, and had more bass, and clearer bass. Turning up the volume really brought out the distortion in the OEM speaker. Just terrible sounding. Pioneer was much cleaner.
Everybody has different tastes but I think you're going to have a hard time convincing people that those crappy, lightweight, paper coned OEM speakers sound better than Pioneer aftermarket speakers.
It's possible the JBL's sound better than the Pioneers, not disputing that. Kind of wonder how they would with a frequency response of 50hz to 20Khz, whereas the Pioneers go down to 28hz. Pioneers are also more sensitive, so will play louder.
But really the only way to know is to have a set of both speakers hooked up to the same source and switch between each set of speakers, noting the differences.
