During Halloween we usually have a fairly elaborate setup and this year I wanted to set up a speaker at the entrance of the path leading up to the front door. I was hoping to use a trusty old microphone that is farily old. I used a mini stereo mic to RCA converter and then added an RCA mono to 2-channel splitter (similar to what I used for my subwoofer). The problem is that I am getting very little sound out of the mic and I have to turn my receiver way up just to get barely audible sound. Even when I don't use the splitter and use just one channel, it is still just as low. So I was wondering:

- Is it a bad mic?
- Are there too many connectors?
- Do I need a second amp to boost the mic. feeding into the amp?
- How else can I achieve loud sound out of that remote speaker?

Thanks in advance.
