## Description

desertcart.com: OSD SMP100 Subwoofer Amplifier 100W Class D Digital Subwoofer Amplifier Rated 100W Max : Electronics

Review: Excellent Quality at a Low Price - Received this OSD SMP-100 subwoofer amp on January 9th 2020, after looking at different models this one made the most sense. After hooking it up and doing my tests this amp was exactly what I needed to include in my whole house audio system. This sub amp works excellent wired into my receiver and my 4 zone 8 speaker selector switch for my ceiling speakers with a separate not passive but an 8 inch active subwoofer, if it is wired and set up correctly this little amp @ 80RMS 100watts of power into 4 ohms can deliver enough power to shake my whole house at quarter of the volume from watching a movie or playing music it’s very clean sound with no hum feedback, it has a phase control to adjust for sub placement, a crossover control so you can adjust and set the low pass to your desire level and an overall volume control to set the desire volume, it will automatically switch off after 15 minutes if no audio signal is detected so no need for you to switch on and off manually. My recommendation is not to use speakers that are more than 8 inch 4 to 8 ohms as stated in the manual. Following a correct set up this little amp will deliver a clean solid deep bass without being out of phase with your system. This sub amp can also be used for powering an in-wall passive subwoofer like the OSD IWS 8 series which I will be doing later.
Review: So far… - So good! Had to set the auto-off to 30 minutes. Frustrating when it turned off every 5 minutes…

## Questions & Answers

**Q: how much power rms at 8 ohms?**
A: The manual mine came with "the 1000 Watt version" -- details it at providing 497 watts RMS at 8 ohms.

**Q: Anyone have an issue with the speaker out port not working?**
A: First off , do you have a audio signal out from the receiver/ amp to the input of subwoofer? Please check wiring diagram of the manual it should work.

**Q: Does the SMP100 require a 12v trigger cable to work properly?**
A: The SMP100 includes auto sensing that turns on the amp when an audio signal is detected then turns off automatically after 15 minutes when a signal is not detected, but it also has the manual on/off switch.

**Q: Will this work with a polk s35 center channel speaker?**
A: Yes. But this amp would be overkill. Simply get an a/v receiver instead.
