Still looking for an amp. Still don't have a clue what's good and what isn't. Everything in the car audio market seems to be focused on 19yr olds in hot hatches and so is rather short on meaningful specs or analysis. I turned up a brand that I think is German, Rainbow. They seem to have 3 models, one of which, "Germanium" is substantially more expensive than the others. Can't find a review anywhere though. Anybody have any experience/opinion of these? I just want a simple, quality couple of channels of amplification running off 12v. I'd happily put home kit in there if I knew of something that would run OK off 12v.
