[Hot Rod]

I didn't think my bass control did anything at first. Then after more listening, I realized it worked but didn't boost much. Also, at roughly 80% volume or higher, even though it's not very loud, cranking the bass up will cause audible clipping. So I think somewhere there is low voltage and somebody is getting starved for power. Sure wish there was a voltage chart for this puppy.

What you said about the two channels made me think of something. Would it be possible that the radio is only using the treble channel to power all 3 speakers and the bass channel is inop? That would make perfect sense of my symptoms.
