## Questions & Answers

**Q: I can connect this to the subwoofer output of a Yamaha RX- V675 for a passive subwoofer 8 "  http://www.amazon.com/CORPORATION-Product-TIC-TFS10-SL-**
A: This is a powered amplifier, which you install in a passive subwoofer, to convert it to a powered subwoofer, if your amp has a low level output for a powered subwoofer, typically an audio jack. If your amp has R & L speaker connections for the subwoofer, they connect to a passive subwoofer.

**Q: Can I use this to push coaxial speakers? Or does this only work with subwoofers because there's no cross over filters**
A: It has a low frequency cut-off, so it will only act as a subwoofer amp.

**Q: I've had this amp installed on a sub woofer. Decided to use it with a stereo amp using the speaker inputs/ outputs. No sound from the right output. ??**
A: Sorry, I can't help you, I didn't hook mine up that way. I ran a single sub cord to the right channel of the low level input and it sounds great.

**Q: What is the red and black wire called ?**
A: Red = Positive.      Black = Negative
