## Questions & Answers

**Q: What are the dimensions, trying to replace amp on a klipsch rpw10**
A: The specs are on the Dayton Audio website.  The SPA-250 page is here:http://www.daytonaudio.com/index.php/spa250-250-watt-subwoofer-amplifier.htmlOverall dimensions are listed in the spec table near the bottom of the page.  Cutout dimensions are in the last paragraph of the text portion of that page.  The cutout dimensions should be 8.5" x 8.5".  Be aware that the amplifier unit is 5" deep, and may require trimming of the internal baffles of a subwoofer cabinet.

**Q: Is this amp stable down to 2 ohms?**
A: probably not

**Q: Can I power a driver in the front and shakers from the back using the high level outputs at the same time? The bass shakers are two ohm buttkicker min**
A: The outputs are a by-pass of the inputs. The idea of this amp is to send full frequency audio (20 -20kHz) in and full audio out. The plate amp strips off low frequencies (below 200 Hz) for a subwoofer or shakers. So assuming full spectrum audio in, you would not want shakers on the high outputs. If you did this, the shakers would be shaking most of the time which would be very annoying. As far as impedance, you must normally keep the load between 4 and 8 ohms. (This depends on the amplifier’s design.) So if you have 2 ohm shakers, you would connect 2 in series to get 4 ohms. (Ohms law).

**Q: Low frequency ranges. Will it do 32hz**
A: It should do 32Hz quite well. With a test cd, mine had no problem at 16Hz although the subwoofer was moving air but difficult to hear.
