Reply To: off-grid stereo conection?

I finnaly used logic to figure it out: the red ACC wire connected to the yellow wire; positive side of the battery. there was no other way to do it. The black wire was the neg ground.

And the steeo works fine at 14.6 volts. At 12.5 volts it drops only .04 volts (volume setting 13). I do not know how many watts that is. But it is less than most of my LED ligths.

And I am using two large coaxel speakers at 4ohms 40watt max each. I think if I turned it up all thet way my ears would pop.

You say I could use 8 ohm speakers???? I have several of those left over from old stereos.  I was thinking about more speakers for the rear channels, in another room.
