My old Kenwood KDC-519 receiver in my F-150 died two weeks ago so I decided to replace it with a new Kenwood Excelon KDC-X492. I liked the KDC-X492 because it has both 3.5mm and USB interfaces on the front so you can connect your iPod and other auxiliary devices. It also supports Bluetooth, Sirius/XM satellite, HD radio, and MP3, AAC and WMA formats. It puts out 50W maximum which is plenty to power the new KFC-C6882ie 6×8” speakers I purchased to replace the factory 6x8s in the doors and in the rear. These speakers sound great, and are a great replacement for the factory speakers. Each speaker is rated at 60W, and has a peak power handling of 240W. They have a 92dB/W sensitivity and a frequency response of 25Hz to 25kHz.
If you are looking for a good set of replacement components for your Ford or Mazda. I highly recommend the Kenwood KDC-X492 with a set of KFC-C6882ie speakers.
