I bought the sister head of that one. Identical but it comes with the built in class-d amp. Sony MEX-XB100BT. Great head so far. I connected a JL Audio sub and amp from a previous vehicle and mounted it in the basement and used Boston Acoustic speakers in the RV's living room. Outside, I bought some Kicker 6.5's that have built in LEDs that can light at night and you can control the light and it's color with a wireless remote control. Audio on these things from the factory is weak at best. Love to upgrade! Sounds like you do to. Enjoy!
