Designed for audiophiles seeking powerful, clean bass with advanced protection circuitry, it offers professional-grade performance in a compact, clip-on form factor. ## Description Product description A Kilowatt of clean, reliable power The Dayton Audio SPA1000 is one of the most technologically advanced subwoofer amplifiers on the market today! The Dayton Audio SPA1000 subwoofer amplifier is based on a state-of-the-art Class-G circuit topology that combines the proven high power, high fidelity characteristics of a Class-AB amplifier with a patented tracking down converter power supply to achieve an operating efficiency up to 86%. You get the efficiency of a Class-D amplifier without compromising audio quality and reliability. The Class-AB output stage provides the clean and low-distortion sound that audiophiles demand, without any of the instability problems that plague other high-efficiency amplifier designs. Channels: 1 Power Output @ 4 ohms (RMS): 950 Watts Power Output @ 8 ohms (RMS): 500 Watts Frequency Response: 20Hz - 200Hz Inputs: 2x RCA Inputs, 1x LFE Input Outputs: 1x Powered Output Built-In Equalizer Manage room nodes and resonances with the simple 1 band semi-parametric EQ LFE Direct Input Bypass the protection filters and crossover functionality with the LFE Direct input, perfect for use with high-end cinema processors Variable Crossover Maintain a smooth transition from your full-range speakers with a variable low-pass filter. Phase Switch Correct misalignment between your speakers and your subwoofer with a phase inversion switch Class-G Innovation The American-designed and engineered SPA1000 plate amplifier uses a patented Class-G topology that continuously tracks the input signal to modulate or control the voltage available to the output stage. This "tracking" capability delivers the exact amount of power based on demand instead of constantly keeping it in reserve, so the output stage only draws the amount of power that is required at any given time. Less energy is wasted as heat, and more power is available for the subwoofer driver. With its enhanced thermal management, the SPA1000 is an upgrade over previous models—making it a nearly bulletproof amplifier choice for today's demanding HT audio and music playback applications. A-Class Features On the SPA1000, the input and output connections are through your choice of either line level RCA connectors, or a direct LFE input which bypasses the filtering of the amplifier. A stereo input signal is summed to mono and sent to the internal low pass crossover, which is selectable from 50 to 200 Hz; the input gain sensitivity is fully adjustable as well. also included is a phase reverse switch, which helps you to achieve the best acoustical match with the rest of your speakers. Dial in the perfect tone with the single band EQ. A large surface area heat sink is combined with internal overload, thermal, and short circuit protection so that you can expect years of reliable operation. Additional Features 1. Low-Level Inputs (Left/Right) - RCA Style jacks that will accept standard line level inputs from a pre-amp level source. 2. LFE Direct Input - RCA Style input jack to bypass the internal filtering for a pure signal to the subwoofer 3. Power Connector Input - Accepts IEC plug for connection to mains 4. Volume (Gain) - This control will match the amplifier's input sensitivity to the output of the pre-amp source. 5. Frequency (Low-pass crossover) - This sets the highest frequency the subwoofer will reproduce and has a range between 50-200Hz with a slope of 18dB/Oct. 6. Power Switch - On, Off and Auto mode. When the “Auto” position is selected, the amp is in “stand by” mode until an input signal of about 10 millivolts or greater is detected. The amp will go back to standby mode 10-15 minutes after the input signal stops 7. Power LED - When the power switch is moved to the “on” position, the LED will illuminate green, and the amp will be in “On” mode. If the protection circuit detects a short circuit or thermal overload the unit will shut down and the LED will turn red 8. Phase - This two-position (NOR = 0° phase and REV = 180° phase) switch helps to compensate for differences in the acoustical and electrical characteristics between the subwoofer and the main system speakers. 9. Frequency (EQ) - Adjust the center frequency of the single band equalizer 10. Bandwidth (EQ) - Adjusts the quality (Q) of the equalizer band 11. Level (EQ) - boost or cut value of the single band equalizer 12.Amplified Signal Output - Solderless disconnect terminals for driver connection: Red = 0.25" / Black = 0.205". Review: Very Nice Features and Power - So I purchased this to replace my Klispch 115 SWR amplifier after it died. The difference is night and day as far as features, build quality, and power goes. I doubt the Klispch stuff makes more than 250w with lightening as a power supply. This SPA 1000 is definately worth the price at about .50 per watt. Not too mention the clipping protection, great EQ, and AB class with a massive Xformer. I actually threw the Klipsch woofers in the trash where they belong and installed Sundown subs. The house is now powered with 3 of these amps on Sundowns in Klipsch enclosures. What a difference! Review: don't waste your money. - Product looks legit but it has serious ground humming and it cannot handle 1000 watt speaker at 4 ohms like it say. It cannot handle gain at half way without shutting off. I constantly have to turn it off and back on again for subwoofer to work. Also the automatic trigger turn on sometimes work sometimes doesn't. I tried everything from buying new rca shielded wires to plugging everything into same power conditioner outlet to using isolators. Nothing works.. I tried contacting them but no reply. I explained my problem not wanting to return it but to help me fix the problem and no answer. Just put out a little bit more money and get a Monolith 12 with none of these problems. ## Features - High power Class-AB output stage for clean, controlled output - Patented tracking downconverter power supply for high efficiency - Toroidal power supply transformer - Low frequency parametric EQ allows you to boost or cut for custom-tailored sound - Advanced soft clip circuitry improves headroom and protects woofers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003FWCHGA | | Best Sellers Rank | #153,692 in Electronics ( See Top 100 in Electronics ) #960 in Audio Component Amplifiers | | Brand | Dayton Audio | | Brand Name | Dayton Audio | | Customer Reviews | 3.7 out of 5 stars 50 Reviews | | Item Dimensions | 11.94 x 5.26 x 11.94 inches | | Item Weight | 22.65 Pounds | | Item dimensions L x W x H | 11.94 x 5.26 x 11.94 inches | | Manufacturer | Dayton Audio | | Material Type | Metal | | Maximum Supply Voltage | 230 Volts | | Model | 300-809 | | Mounting Type | Clip On | | Number of Channels | 2 | | Output Power | 950 Watts | | Part Number | 300-809 | | Specification Met | Multiple, Including Audio Equipment, Electrical Safety, and Energy Efficiency Standards | | UPC | 844632081668 | | Voltage | 5 Volts | ## Product Details - **Item dimensions L x W x H:** 11.94 x 5.26 x 11.94 inches - **Manufacturer:** Dayton Audio - **Maximum Supply Voltage:** 230 Volts - **Mounting Type:** Clip On - **Voltage:** 5 Volts ## Images ![Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier - Image 1](https://m.media-amazon.com/images/I/81mebeenW6L.jpg) ![Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier - Image 2](https://m.media-amazon.com/images/I/81Yz-1d3ZgL.jpg) ![Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier - Image 3](https://m.media-amazon.com/images/I/71NTIn7RFyL.jpg) ![Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier - Image 4](https://m.media-amazon.com/images/I/81VyfcwNlxL.jpg) ![Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier - Image 5](https://m.media-amazon.com/images/I/81wOGcj+5CL.jpg) ## Questions & Answers **Q: Can i use a 1000 watt car subwoofer with this** A: Yes I use this amp on a Skar 800w rms subwoofer in the house and it threatens to break every window of said house so yes you can use car subwoofers but just be sure to wire them to 4ohms or this or any house amp will trip their built in circetbreaker. So in other word don't wire them like you would a car that being 1ohm-2ohms or lower. Only 4ohm or higher with this amp. **Q: What is the rms power of this amp?** A: Warning this is a 1000 watt RMS amp at 4 ohm not 500 watts !! I have the 500 watt model still in service almost 5 years now ...... Keep Freq low at subwoofer specs and go easy this amp will blow a cheap sub or cause damage to the amp if not used properly !!! **Q: what subs can work with this Amp???** A: This amplifier can drive any subwoofer rated at 4 ohms or higher. **Q: I have a Polk audio dsw 4000 can this amp work's with my unit** A: Yes and no... It has enough power for the Polk but unfortunately it will not fit in the Polk cabinet... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Nice Features and Power *by S***S on August 6, 2022* So I purchased this to replace my Klispch 115 SWR amplifier after it died.

Pros : I really like the subwoofer controls and eq although I ended up using the LFE input which bypasses all controls except the gain. Very well built with a beefy transformer. Auto power on sensing seems to work well so far. Cons : Nasty "thump" when powering on(not when auto sensing though). Would be better if a 12v trigger option was offered. ## Frequently Bought Together - Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier - FosPower Banana Plugs 12 Pairs / 24 pcs, Closed Screw 24K Gold Plated Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems - Amazon Basics Speaker Cable, Easy Assembly, 16-Gauge, Bronze, 100 ft --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/5689871-dayton-audio-spa1000-1000w-subwoofer-plate-amplifier](https://www.desertcart.com.ar/products/5689871-dayton-audio-spa1000-1000w-subwoofer-plate-amplifier) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-31*
