I have just put some 6x9 speakers into the rear parcel shelf of my car, running from a factory headunit. Have found that when all speakers plugged in and the headunit on, no speakers make any sound.

When the 6x9 speaker on the left is disconnected all the other speakers start to play fine. if you touch the negative wire only to the negative terminal of this speaker all the other speakers turn off. Then if you touch the positive wire to the positive terminal of this speaker a loud buzzing is emitted.

I have replaced speakers before and don't see why this is happening, any thoughts?

Did you remove the speaker connector from the old speakers and use them on your 6x9's?

It could be many things including: bad speaker; bad wiring; too many speakers creating low impedence. Try swapping another speaker into this location and see if the same thing happens.

It sounds like that speaker wire is ground out. Run some speaker wires from you deck and hook it to that speaker just to test it. If it works, that's the problem.

pull the speaker outta the box and check the conections inside the box, Mabye the wires are touching, also check the tinsel leads and make sure they arent grounding out on the chassis

sounds like a grounded speaker wire. Make sure the insulation isn't worn and exposing the wire anywhere. Easiest way to test for it is to pull the speaker out and test it independantly outside the car (if it isn't the speaker then it's most likely in the wire)

I am thinking that it is the speaker or the impedence problem myself.

If he disconnects the speaker at the speaker and the problem goes away then that rules out a wire problem cause the short would still exists.

The short may still exist but the circuit would no longer be complete. I may be wrong, but I think there could still be a problem with the wiring.

The problem is with the speaker. Test the voice coil of the speaker with a meter. The speaker terminals are either shorted to the metal basket which will be connected to the car's chassis, thus grounding out the speaker leads from the head unit. The other possibility is that the speaker is shorted internally. The impedance measured across the speaker terminals should be about 4 ohms. If it is less than 3 ohms its bad and needs to be replaced.

heck, grab a meter and meter that speaker wire at the HU... if you get a continuity to ground reading you've got a shorted speaker wire...UNLESS.... the short is from the voice coil to the basket/magnet of the speaker... so, if you do get a reading then disconnect the speaker wires from the speaker and retest it... if you still have continuity to ground you have a short on the wire, if however, you no longer show a short to ground then you have a bum speaker.... last way to confirm this is to meter from both the positive and negative terminal of the speaker to the basket of the speaker....if you get a continuity reading you';ve got an overexcurted voice coil short in the speaker itself......

simple, yes??
