## Questions & Answers

**Q: What ground do i connect to? the 12v ground of my car? or is this for a switched live? does the unit require power in some way?**
A: If you're connecting via a T-harness (most are labeled you connect to the black (usually black) wire (note you only need to connect the earth if you're getting distortion or are using your RCA's as remote turn on

**Q: Can i only connect one speaker to this to use on my sub/amp? or shall i connect one speaker twice or can i just use one left side speaker only?**
A: I use this with an amplifier without sub output.  Just connect the converter to the speaker output on the amplifier.  The output on the converter is a line level output to two phono (RCA) sockets.  This works for me because my sub has two line level phono inputs.
Some subs have just one phono input and if this is the case  then you probably need a splitter like this one
