The OEM speakers that come in RVs are junk, anyway. I replaced the interior speakers in my travel trailer with Polk Audio just to improve the sound (and get some high frequencies so I could understand the dialogue in movies). When we purchase a fifth wheel for full-timing, I expect to replace the audio in the entertainment center altogether.
