I have the only Custom Autosound stereo on the planet that actually works....at least that's what I have been told on this website
I have looked at the Retrosound stereos also, and they look the same to me. They are not the best made units, that's for sure...but then again, none of them that are going to fit our trucks without cutting up the dash are very well made. I put Bose speakers with mine, and it sounds fantastic.
My other truck has a factory AM/FM in it, and although the sound is clear, the volume sucks. Once I fire up the truck, I can't even hear it anymore. 1972 technology vs. today's technology.
