Speaker Wiring
nodcc4me:
When you are wiring the speakers, why not try both ways before you put the shell back on and see which you prefer? It's just two solder connections.

Parallel will yield higher volumes. I typically will run my dual speakers in parallel when they are rated to handle the wattage. With a 4 ohm resistance, the Railpro amplifier will output 2 watts of power. Not every speaker is rated to handle 2 watts of max power, and if they aren't they can be damaged. I have a few sugar cube speakers that have a max rating of 1 watt, so I did series on those. They are definitely quieter, but I'm also not at risk of destroying them.
Really though, as long you aren't maxing out the volume you should be fine with things in parallel. If it's too loud it can always be turned down. It's easy to adjust the volume on Railpro, including the individual volume of each sound. Very customizable.

The amp output is double at 4 ohms compared to 8 ohms but you are driving two speakers. So each speaker sees one half of the power. Sugar cubes are 8 ohm if I am not mistaken. That means each dissipates 1 watt staying within its rated power.

I believe that's correct. I had a set of sugar cubes I was trying out that were rated at 0.5 watts (didn't realize when I bought them) so I kept the wiring in series to keep them within range.
Either way, wiring in parallel typically works better and gives you more room for adjustment. You can always turn down the volume. On that note, if Scale Sound Systems ever gets speakers up and running again, you will definitely want the 4 ohm version of the Coeval (double) speaker and not the 16 ohm. I have both and my 16 ohm is maxed out on volume to be on par with my other locomotives. The 4 ohm version can be kept much lower.
