I personally wouldn't push the amplifier on the RS Commander that hard. While they have it running a 4 ohm load, the power dissipation goes WAY up, over twice what it is for an 8 ohm load. That tiny chip can't really dissipate well over a watt without significant heatsinking, and it has none. You're playing with fire running this with a 4 ohm load.

John,

It appears that this thread focus' on speaker ohm's. The new ERR railsounds I am installing has a 8 ohm 1 watt speaker. The Atlas Dash 8 (2005) I am installing it in has a 8 ohm 2 watt speaker in the belly fuel tank. What is the effect of the 2 watt speaker compared to the 1 watt supplied with the kit on the sound board? Will it drive the sound board harder, maybe causing it to over heat or will it be easier on it? Thanks.
