## 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.
