## Questions & Answers

**Q: What is the voltage of the RCA outputs?**
A: 8v

**Q: What is the difference between the 7 and the 9 band eq?**
A: More adjustable frequencies, therefore more sound options

**Q: pre amp, well how many wattsssssssss**
A: There is no limit to how many watts you use - this is *pre* amp, so it goes before any amplification.

**Q: Can this be hooked up to a factory unit?? It's for my work truck and don't want to spend money to replace factory unit.**
A: This will hook up between your head unit and any amplifier that takes RCA inputs.  But you MUST have a separate amplifier.  This will not drive speakers directly.
