[AFB24911S]

Pelican Parts Brain Trust,

I just put an amp in my 1977 911S with its original Blaupunkt radio, and the sound improvement was good but not great. I only have the two original speakers in the doors, and I'm wondering what the best ways to continue to get better audio sound might be.

Should I upgrade the radio to a newer unit, like the Blaupunkt SQR 46 Bremen or the Porsche Classic unit?

Or, should I add speakers to the rear shelf? Maybe a subwoofer? An equalizer? What is my best bet to improve sound quality?

Thank you in advance!
