I have an older Retro Radio/Sound for the '66. They seem to have changed the name and features. The closest comparison would be the Motor 2B, but mine doesn't have bluetooth and I don't think it has 300 watts of power. It does have the 25 watts X4 channels. From what I remember from 7-8 years ago, it sounded rather tinny, but it is a much older model and has, most likely, improved.
I have had a Retro Sound. I have Aux and USB ports so I can play music from my phone. This does come in handy if I am using Maps on my phone, as I will hear the directions over the radio.
