Aftermarket radio wiring

I have a 1980 300SD in which was installed an aftermarket (Blaupunkt) radio. The left front speaker is the only one which currently works. I have checked continuity on the other speakers: there appears to be none. I also receive only a couple of stations, suggesting the antenna connection to be poor. I suspect that all of these connections were violated when the previous owner had the car repainted. Where do the wires for the other three speakers run? what would be the easiest way to access the speaker and re-establish wiring to the radio chassis?
Thanks,

616 617 Diesel exhuast manifold nuts

I recently replaced my exhaust manifold on my 617.951 diesel and couldn't find new copper locking nuts anywhere so I reused the old ones with red thread lock. It's been about five months since then and I noticed a little oil around the front of the gasket, I checked the front nut that I can get to and it was loose enough that I could turn it with my fingers.
My question is, where can I find new locking nuts and what is correct torque for these nuts? My Chilton manual said 18-21 ft lbs but that doesn't seem very tight. Thanks for your help
