I am the happy owner of a 2018 Accord EX. However the stock sound system leaves much to be desired. So i replaced all 4 speakers with Infinity REF-6532ex. When i took the front driver side door off i noticed there was water on the factory speaker. Charlotte NC has seen a lot of rain recently and we had a downpour the day before i switched out the speakers so while i expected there might be a little moisture in the door, i was surprised at the amount and that it was even on the speaker. i dropped the car off at the dealer and their reply was water in the door is normal and the moisture barriers were in place. Has anyone else noticed excessive moisture in the door panels? By the way, the infinities are an improvement over the stock speakers. However now looking at an under seat sub for just a little more low end. Any recommendations?
