so it works great.
running a jack to RCA splitter out of the mic, into a very old JVC manual equalizer amplifier( 25w per side) and out to a pair of 3.5 inch speakers that are in an old jeep sound bar. the reception and sound so far is good. this is using the HT antenna, i have not tried the truck antenna to see if i get better reception and quality.
I still have not tried to transmit and receive, but am/fm reception and weather channel is nice and loud. and i hardly have to turn the yaesu volume up past the third click to have loud sound, i think the lower volume output out of the radio will save on battery life.
