3 different camper now, we use a Bose Soundbar. It wasn't cheap, but it's been used in our house, then 3 different trailers. Plugs in with either a fiber optic cable or an HMDI cable. Sound is much better than anything in the camper's entertainment center. Ended up getting another sound bar (Best Buy, not a Bose), and use it on the main television now. It has the Bass speaker, tweeters, surround sound. We run the wires around and have absolutely awesome sound in the camper. When that Base is rolling, the entire trailer rumbles. We can hear it rumble a couple hundred feet from the camper (if we blast it loud enough) .... which we don't. I think the thing would break our ear drums.

Sometimes, what's installed in our campers is just junk. And if you want something substantial, you've just got to replace the junk with something else and then be forever happy!
