DO NOT EARTH A SPEAKER'S (-) TERMINAL TO THE CHASSIS OF THE CAR!!!!!!!! It may work, but it is VERY BAD for both the speaker and the headunit. I do not know where you got this information but i suggest that you take it and throw it into the COMPLETE BULLSHIT pile. Here is the method of finding out the correct phase of your speakers: Take one battery of any type (i like 9V) Find the pair of wires for the speaker in question and briefly touch the speaker's wires to the battery. Take note of which direction the speaker moves when it "pops" If the speaker moves OUT, you have the correct phase (wire touching + on battery is the + wire for the speaker). If the speaker moves IN when it pops, you have a reversed phase. That is all. Wow, that seems a bit rude. Did I ever suggest that it be done? Nope Was my information incorrect ? nope. Was it complete bullshit as you put it? nope The reason I mentioned it was because that wiring setup was found on some amplifier wiring in a car, and sorry I can't remember where, I was just bemused at the time as to why people would bother wiring it this way. But I also realised that, well It would work. In fact the information was used simply to show the lack of an AC circuit. [Report message to a moderator]
