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! ## Features - Line-level and speaker-level inputs for connection to any system - Variable 2nd order low-pass crossover from 60 Hz - 180 Hz - Speaker relay prevents turn-off thumps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002YUMY8 | | Best Sellers Rank | #202,545 in Electronics ( See Top 100 in Electronics ) #328 in Home Audio Subwoofers | | Customer Reviews | 4.0 4.0 out of 5 stars (103) | | Date First Available | August 31, 2009 | | Is Discontinued By Manufacturer | No | | Item Weight | 2.5 pounds | | Item model number | SA25 | | Manufacturer | Dayton Audio | | Product Dimensions | 7.48 x 4.72 x 8.66 inches | ## Images ![SA25 25W Subwoofer Plate Amplifier - Image 1](https://m.media-amazon.com/images/I/81X8xu5SGTL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a great product, that work as indicated *by A***R on May 25, 2012* This product was easy to setup.

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. ## Frequently Bought Together - Dayton Audio SA25 25W Subwoofer Plate Amplifier - FosPower Banana Plugs 6 Pairs / 12 pcs, Closed Screw 24K Gold Plated Banana Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems - Amazon Basics 16-Gauge Speaker Wire Cable, 100 feet, Bronze --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/2313879-sa25-25w-subwoofer-plate-amplifier](https://www.desertcart.ni/products/2313879-sa25-25w-subwoofer-plate-amplifier) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-25*
