The Dayton Audio SPA250 subwoofer amplifier produces 250 watts of clean power output, and combines with a host of flexible user options to make it an unbeatable choice. The SPA250 features RCA line level and banana jack speaker level inputs and outputs, automatic power-on that is triggered by any audio input signal, and a phase reverse switch to match the subwoofer to your room and your other speakers. A single SPA250 can accept a stereo input signal and combine it into mono, which is preferred for sub bass reproduction. The internal low pass crossover is fully adjustable between 40 and 180 Hz, and of course the amp has built-in protection against internal and external faults.

High-Level In/Out
High-Level inputs and outputs let you use any amplifier to feed the SPA250 and send it out to the full range outputs. Perfect for systems with no subwoofer output
Auto-On
When no signal is present, the SPA250 can shut itself off until you need it most!
Class-AB Reliability
The classic AB topology keeps distortion to a minimum while providing a peak wattage of 500W to your driver. the SPA250 is perfect for subwoofer duty due to its low noise and reliable performance and protection features.
A-Class Features
On the SPA250, the input and output connections are through your choice of either line level RCA connectors, or high-level inputs for maximum compatibility. A stereo input signal is summed to mono and sent to the internal low pass crossover, which is selectable from 40 to 180 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. 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.
Note: Speakers with a burned voice coil are not returnable for exchange, repair, or refund credit, as this is not covered by its warranty.
