I used this forum many years ago, and I was more than pleased with the help i received. I am now starting another project. I plan to use an old car amp that I have to create a speaker system for my college apartment. So far I have taken an old computer power supply to power the amp, and it works great! The amp does about 175 watts per channel and it is a dual channel. It can be stable down to two ohms. My question is why are all home audio speakers only stable down to 4 or 8 ohms? What am I missing? Any other advice would be appreciated.
