Dayton Audio SA25 25W Subwoofer Plate Amplifier

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!

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 brother 0) 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..

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!

Very nice amp, plenty of power to drive two 10" woofers in a 14' X 28' room for stereo music, movies & Wii. The only negative is the power switch is on the volume control, so every time you use the amp you must re-adjust the level. Or leave it on all of the time

I was going to repair the amp in my old Jensen sub, but decided it was easier to buy this. It looked like the plate size was the same, but it was slightly larger. I needed to trim the back of the cabinet to fit, but once done fit fine. Even the speaker connectors were exactly the same as the old amp. From what I can tell, the sub frequency cutoff and gain work better than the old amp did. This is same power output as old amp even though Amazon says it was 60. This is what I used it in. https://www.amazon.com/Jensen-JHT525-Theater-Discontinued-Manufacturer/dp/B000065UTR/ref=cm_cr_arp_d_product_top?ie=UTF8

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 ?

Used it on a Kenwood passive subwoofer I picked up at Goodwill. Easy to install, but it failed to work after about 15 minutes. Ended up returning it. I did reorder another one from Parts Unlimited, which is working perfectly. It is a great product, just be aware that there is a chance that you may get a defective one. The only other negative is the lack of an automatic mechanism for turning on and off the unit. The on/off switch is part of the volume knob which means that you have to reset the volume every time you turn on the amp. I have the subwoofer paired with my Dahlquest DQM-5 speakers and when adjusted properly provides a nice clean bass to the sound. System is located in our basement in a medium sized room. It fills the room nicely even at low volume. One star taken away due to the failure of the first unit and the lack of the auto on/off switch. four stars for a great product otherwise.

This worked great for 3 years, then it died. Converted an old boss sub to a powered with this.

外寸で縦横15.9cmくらい、奥行約6cm、取付用の開口は13cm四方くらい。 ウーファー接続用の赤黒線（約45cm）が中央付近から出ている。 実測してサイズが分かったので、これからユニットの選定とエンクロージャーの設計予定。 ゆっくり楽しみます。

Funciona bien, solo que da mas potencia de la especificada, conecte un bajo de 89db y según soporta un máximo de 90db, resulto que a medio volumen hizo cartones mi bajo dejándolo fuera de servicio, recomiendo usen uno de 100db a 120db para evitar fallas.

小型システム用の自作ＳＷ(ＴＢ10㎝×２発・バスレフ)に使用してます。 海外の方のレビューではトラブルもあったようですが、今のところ全くノートラブルです。 ２５Ｗは非力に思われるかもしれませんが、私の使用環境(約１０畳)では十分な出力があります。 何より自作される方は分かると思いますが、ＳＷを作る際の「…で、アンプどうしよっかな」という心理的負担から解放される上、プレート型なので特別な工作もなくスマートに一体型ＳＷが製作できるのは非常に満足度が高いです。 あえて改善点と言えば、ボリュームノブが電源スイッチを兼ねているので毎回ゲイン調整が必要な事と位相反転スイッチが無いことですが、値段を考えれば特に不満ではありません(上位機種ならオートパワーと位相切替えがあります)。 国内メーカーに同等の商品は皆無、カー用は電源に困る、アンプモジュールは選択肢は多いがインストールが面倒etc… ネットで気軽に購入できるホーム用ＳＷアンプとしてはDayton一択じゃないでしょうか。 自作派の方に是非おススメです。

He comprado 3, y ninguno ha funcionado, alguno sonó un par de horas y dejan de hacerlo
