Great Device
I bought this device because my old home theater in a box used a passive subwoofer, and when I bought a new Denon receiver, I found it wouldn't work with the sub. After pricing out some active subs, this ended up being about 20% of the price of them. The day I got it, I plugged it in and turned it on, and like magic, my sub was working again. I didn't want to modify my sub, so I built a separate box for this amp out of a 24x24 inch piece of plywood that I picked up at Lowes for $3.50. My artsy girlfriend stained it with some ebony stain, and now it looks like it belonged with the set all along. Interestingly, this thing actually gives my sub more power than it had before, when it was hooked up to a Sony receiver. With adjustable settings, you simply couldn't ask for anything better for only $30.I'm thinking about buying a few more of these simply to convert some older passive subs into active subs for my friends. Definitely a good buy.

Randomly stops working
I've had this for about a year. I could tell after I first hooked it up that it is not a quality item. I have it hooked up to a single subwoofer and am using the low level input plugged into the left channel only for single channel. The sub will faintly play a local radio station unless the speaker wires are painstakingly placed. It also cause a noticeable hum in the sub at lower volumes. The worst problem is that it will sometimes just stop working for now reason. It will appear to be on, but no sound will come out at any volume. The only way to fix it is to unplug and replug it, just turning it off doesn't help. Sometimes I can use it many times over several days before it stops working, other times it stops after 5 minutes. From visual inspection, it doesn't appear to have any leaking capacitors, but that's about as far as my electronic diagnosing skills go.

Almost Perfect.
This amp is a solid amp with a good sound. I tried it on both a 4 inch sub and an 8 inch sub (a pyle tube 400 watt sub). It filled the entire living room with nice bass. However there is a couple of gripes (though one of them may be unwaranted. For starters this amp does not have a power switch but rather a volume/power knob. It works but every time you want to shut it off you have to reset the gain when you turn it back on. I bought a cheap powerstrip though with a switch so it isnt much of an issue. The other thing is that this amp does not come with a back (though i did expect that so again probably not fair to judge it that way). Either you will have an enclosure for the sub and put the amp on that or you will need to build a small enclosure for this since all of the raw components are exposed. Now for 42 dollars is it worth it? From the sound quality yes and the decibels it provides. As long as you buy this amp with those 2 things in mind you will love it.

Dayton Audio SA25 25W Subwoofer Amplifier
This is a nine compact unit that works well, but be aware of its limitations. The 25W rating if for a 4-0ohm speaker. Since many sub woofers are 8 ohm, it's real RMS will be half that value. Still, for a single small room it is fine.If you need more power for a larger space the Dayton SA70 (its bigger brother0) will probably fit the bill. Again, be aware that for an 8-ohm speaker the RMS will be half the listed value. Plate amplifiers also need an enclosure. The unit can be connected to your amplifier by either a pin cable connected to a sub-woofer out or by routing the front speakers through the unit. I suspect that both connections are ideal. Unfortunately there is no manual accompanying , the unit. The company's response was that it was under revision and will appear on their web site.- maybe so- but after several week that is still not the case. All things considered, it is still a nice unit, keeping in mind, it's limitations. Recommended for converting a passive sub-wooffer into an active one..

Amplifier is not working
I bought this subwoofer amplifier based on other customer reviews but it is not working as it come with no wiring or manual and at is not working . also no costumer support i try to connect this amplifier connecting the pre amp signal from the receiver subwoofer RCA pre out to amplifier RCA Pre Amp in and the output from the amplifier to subwoofer speaker but nothing is working. i see to hanging wires from the amplifier with two terminal and i am not sure if this wires have to be jumper or connected to activate the relay. Because but no luck to contact the seller can some help to get it working or may be it is defected and need to be return .Also is the seller provide warranty for this amplifier ?

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!

Okay sound but poor response curve properties.
This amp has a good sound, but if you are looking to drive signals in the 40 to 80 Hz range, you should consider a different amplifier. This amplifier does not have a flat response curve, and with the crossover adjustment set to the highest range (180 Hz) the amplifier starts to attenuate as high as 200 Hz. By the time you reach the lower frequency range, the attenuation is very high, making this subwoofer amp a poor choice for subwoofers.
