I am generally very happy with my RV, but was very dissapointed at the low quality speakers in the outside entertainment system. It has 2 4x6" speakers, one of mine even had a terrible vibration at certain levels. Rather than have the dealer replace them with the same junk, I found a pair of Rockford Fosgate speakers on Amazon. What a difference! I still may see if I can place a decent amp behind the scenes someday, but the speakers alone are a great upgrade.
