Dayton Audio SPA500 500W Subwoofer Plate Amplifier
Hi! How do you change it to 220 volt from 110volt?
This is 110 volt out of the box. No modification is necessary for 110 volt operation.

How does the auto on/off work.
When the receiver sends a low voltage signal through the subwoofer output, it acts like a trigger to bring the amplifier out of standby mode. Once this low voltage source (receiver) has been turned off, the amplifier will go back to standby after 10 or 15 minutes.

Are the power ratings (273 watts into 8 ohms / 540 watts into 4 ohms) peak ratings or RMS? If peak, what are the RMS ratings into 8/4 ohms? Thanks
These are both RMS ratings.

Should i switch a jumper or something for 230v opeartion?
In order to be used with 230v power, you will have to pull the fuse holder out and rotate it 180 degrees. You can see page 3 section 3 of the manual for these instructions.

The overall depth of the product is 5 1/4". I am assuming this includes the height of the heatsink? How much clearance is required behind the plate? (ie not including the height of the heatsink)
The depth of 5-1/4" is actually the mounting dept, allowing for about 1/4" of clearance for the wire leads out the back of the case.

I see Subwoofers/amps rated showing "continuous" and "peak" power figures, (such as the HSU subwoofers). How do the SPA500 amps power rating relate to these power ratings?
Continuous power, peak power, RMS power, program power, & on and on. Many different methods of rating power. You must review the conditions associated with the ratings. Impedance, total harmonic distortion are important. To answer your question simply compare like with like.
