[QUOTE="Shawn Bialas, post: 800310, member: 64532"] Jason, Ideally you should have 0VDC to your speakers. Putting the 4 ohm resistor in parallel with your speaker is essentially cutting the impedance of your entire system (on that channel). So if it was a 4 ohm speaker you put in, you now how a 2 ohm impedance, if it was an 8 ohm, you have a 2 2/3 ohm impedance. I personally think your head unit should be replaced, I really can't be certain of why this lower impedance system works, but I do know that the resistor you installed is wasting power and causing you to have an unbalanced load (between the right and left channels) on the amplifier. So you will be getting more power out of the lower impedance speaker channel. I re-read what you wrote...I'm not sure if you left the resistor in your system, but if you did, the above paragraph still applies. If not, I have no idea what happened for you, but if it continues to work for you then that's awesome, it seems like the resistor may not have done anything and you might just have had a loose connection to that speaker. I'd say still try to get a free updated head unit though :D -Shawn [/QUOTE]
