Note: Camper manufacturers use things that are in between any regular size. Speakers, stereos, microwaves, etc. , so if you want to "upgrade" you have to go back to them unless you are a do it yourself-er. Luckily, I am. So I made some adapters that look pretty damn good & work great & are way stronger than the factory set up. Yes, speakers & microwaves coming loose & self destructing is a common thing. Stereo is the next thing to get replaced. Not sure that I will tackle that though. Camper stereo & car stereo are 2 totally different things. Wire colors mean all different things.

Just realized that they are $79.99 @ Crutchfield !
