Review: This is a great product, that work as indicated - This product was easy to setup. I decided that I did not want to cut a opening on the side of my sub-woofer for the Dayton Amplifier face-plate, so I went to Home Depot and found a hard plastic box type container that was very close to the dimensions of the Dayton Amp and mounted the face-plate to it with screws. Secondly, I drilled a hole on the side of the plastic box to run the wiring out from the Dayton Amp to my sub-woofer. Thirdly, I ran the sub-woofer wiring from my home theater system amplifier to the connections on the front of Dayton Amp and connected the sub-woofer wiring to the wiring connections on the back Dayton Amp with the wiring coming out the hole I had drilled. Finally, I turned on my home theater system, and the Dayton Amp. I now have deep bass sound that I can adjust. My home theater system sounds so much better!
Review: Great Product, Does what it says to do, and with a Punch! - I was a bit skeptical at first, as it rates 25W, but I wanted to use my old passive subwoofer with my Onkyo system and decided to give it a try as it was the only one I found to be of the proper size. I was very pleased when, after 15 minutes to instal irt on my old sub, I pluged it on my system and Poof! I came to life, adding what I wanted to my Home Theater Room, with a clear and loud punch! Works as a charm, easy to instal and inexpensive. I highly recomend it! And fear not, the 25Wlittle guy delivers, and strongly so!

## 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

### ⭐⭐⭐ I would give 5 stars if it didn't flame out initially because it works / sounds so good.
*by T***B on September 5, 2015*

Mine blew out shortly after I installed it - Parts Express replaced it right away no problems even provided a return freight label. Hoping the replacement holds up. I have another one of these in service for about 8 months now. I think I am going to put a cooling fan on both of them to see if that helps them hold up. They are not used hard - but everything IS made in china now. hard to beat this for the price though - there are no real alternatives for this price so make do. I would give 5 stars if it didn't flame out initially because it works / sounds so good.
