Clarion M502 in 2015 models replacement
When someone does get a good substitute, let me know. I doubt the actual sound will change much unless one does the following.
1) Change the speakers as follows: Remove the Clarion speakers near the front of the trailer, replace these on the vertical face of the overhead, but thoroughly pack the area behind the speaker with a closed cell foam. I am using a Polk Audio replacement.
2) Change the head unit and subwoofer, the sub could be Bluetooth, and powered up only when a signal is received from the head unit.
3) In rear of trailer, remove the current speakers, patch the holes with aluminum after fishing wires to locations in the ceiling so a stereo sound stage is created when in the bed. Under the new mounting areas a firm mount needs to be created, I think this can be done with a very thick closed cell foam, lots of silicone sealer. Possibly, mounting a 3/4 inch plywood panel behind the aluminum would be beneficial. (Done in two pieces)
So, what is the cost....new head unit and matching sub....maybe $400 - 600 plus. Speakers about $200-400. Labor at a shop might be as much as $500.
It requires a lot of work to get sound in the aluminum box, avoiding resonance frequencies is a potential challenge.
And, the television sound, I am planning on using a sound bar under the TV in the main room. This of course after I move the television up about 12-18 inches.
Please understand I am a bit OCD with sound systems even if I am so old I can't hear the difference...LOL
However, at present, the Clarion is adequate for the absolutely inadequately engineered speaker system. IMO, the individual responsible at Airstream for the audio system has no knowledge of acoustical engineering, is making decisions only on an economic basis.
Happy trails and Good Luck
