Hey guys, I'm hoping this is ok to post here. I know there's a sister site for this, but that forum is all but dead, or just starting, not sure which.
Anyway, car's a '78 camaro, so needs to stay with a shaft style receiver. currently i have an old blaupunkt daytona in there with 2 sony xplode's in the back. as is, i can't stand the sound when its turned up to a volume i enjoy listening at. the bass turns to complete flab and mud, while at the same time the highs are harsh and shrill. when playing with the bass and tone controls, there's no middle balance to help out.

Today I tried playing with my old speakers.. some real old pyramids, i forget the exact model. But they sounded basically identical to the sony's. So my guess is that the receiver is no good and isn't letting the speakers do their work. Now, does it make sense that my Blaupunkt receiver is no good? Yes, its probably from the 80's, but it is a top quality brand.

If I need a new receiver, what are my best options out there for shaft style? Should i go for another vintage such as a kenwood or alpine? Or should I go new and go with Auto sound, Pyle, Retro Sound, or something else that I might be missing?
