Actually 200W is overkill, a 4 ohm speaker rated for 60 watts RMS would =
hold up quite well at 12~15 Vdc, but then again with today's rating =
system a 200w rated speaker is what maybe 5 watts RMS?
Seems like the modern rating system is based on how much peak power it =
takes to instantly blow the speaker.
