Then ohm the black to the case. My guess is that they may be connected to each other but NOT the case... reason is they may be using a push-pull amplifier to get the power output, if you ground the speakers you'll blow the amp... but if that was the case there most likely would be a label saying not to ground the speakers... any such label? (this is why you are not supposed to ground a speaker... that and you'll get a lot of noise...) I'm thinking that this thing gets it's ground through the case as the coax cable is attached to the case... which makes sense, you want that as a shield for the CB. So, to solve your problem, ohm the black lines to each other if b1 and b2 are connected then those are the returns for the speakers... if they are connected to the case ground directly then they are just running those lines for the speaker returns... what the meter carefully when you go black to case, reverse the leads when you do... if you get a difference switching the leads you do not want to ground those black lines. :) the other way is to bench test it... make sure you have an antenna connected although you won't damage the CB output amp unless you key the mike... connect a pair of wires to the speaker, if they work, see if they work with the black leads switched... my guess is they will. also, you can optimize the speaker sound by connecting them up so they sound the best... I think the trick is to put it on an AM station... then switch the leads to the speaker until it's the clearest... (I used to be a tv/radio repair man way, way, way back... before SuperDawg was born... late '60s... back when tubes were tubes and transistors were new fangled devices...:) the white wire is dash light? orange power? john ----- - ------------------------------------------------------------------------ Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://AMSOIL.com/redirect.cgi?zo=283461 http://creationwiki.org http://johnmeister.com http://wagoneers.com http://fotomeister.us - ------------------------------------------------------------------------ On Sun, 10 Jan 2010, Michel Balea wrote: # I need to wire that pristine radio that I got for a steal at the local yard. # # I can figure orange (+) /brown (+) and the speakers.
