About 2 years ago I installed a Blaupunkt Alaska CD/receiver in my '86 Carrera along with Infinity Kappa Speakers. The receiver is 40 watts per channel and the speakers can handle 100 watts. No additional amplifier. Worked just fine. However, in the last few weeks if I turn the volume up more than 2/3 after about 10 minutes the right front speaker will cut out. The other 3 speakers continue to work just fine. I can turn off the receiver wait about 5 minutes turn it back on and the speaker will work again. If I turn the volume back up the speaker will cut out again. At low volumes there is no problem. I checked all the connections and they are good. Haven't switched out the speaker yet thinking this is a receiver problem. Am I just overloading the receiver by running the volume too high? Should I get a more powerful receiver or will adding an amplifier solve the problem? TIA!
