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!

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!

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.

Powerful enough to drive a 12 inch woofer in a vented cabinet. I am using it with the gain at about half and the crossover more on the low end and it's sufficient for the movies we watch. My only complaint is that you have to manually turn it off and on, as the power switch is part of the gain knob. Still, a great amp for the money.

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 ?

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.

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
