3 out 4 speakers do not work!

[BootlegCB7]

Well simply put, the only speaker that produces sound in my car is the rear driver side speaker.
The other three sometimes (like 1 out of 10 times) produce sound for half a second then stop.
I read the other thread about speaker going in and out, so I poped off my door panel to check wires (cracked my door handle in the process >_>), the wires are all connected, insulated. So I'm guessin it is my head unit. What do you guys think?

my g/f has the same problem only it's her rear passenger one that works. and i know it's not her head unit cause i swapped in mine and it does the same thing so it's wiring some where thats messed up. i'll be watching this to see suggestions as well. my next step it to follow every speaker wire in the car to find a break somewhere

are the speakers them selfs shot?

[BootlegCB7]

I will post pictures when I get the time to take some.

I doubt the speakers are shot because when they are working for that half of a second, the sound matches the music. I checked the back of the speaker, the soldering and wires look fine to me.
The chance of three speakers breaking at the same time is pretty rare I think.

If all three speakers come in and go out at the same time, that sounds more like your head unit than the wiring. If you can take it out, just run a continuity test on the wires that aren't working consistently.

exactly how do I perform the continuity test? with a voltmeter or something? I'm pretty new with stereo and stuff.

If you have a multimeter, set it to Ohms, and put one of the probes on each end of a particular wire. The needle will shoot all the way to the right (infinity) when the probes aren't touching anything, or if the circuit is broken. If the wire's not broken, it should read zero.

If you don't have a multimeter handy, grab a 9V battery and an LED or something and close the circuit the same way with those. If the LED lights up, your wiring's good.

Look at your cb7 name.

Is everything really bootlegged on your car? lol

Thanks Joey, will try that.

well, this is kinda offtopic, my cb7 is actually bone stock, it is just not performing well, feels like it is a bootlegged car.

[jaysteven]

you can also use the 9volt battery to pulse the speakers
hook the + up to + and the - up to -
dont leave it on too long or it can damage your speakers

i had something kinda like this happen

http://www.cb7tuner.com/vbb/showthread.php?t=43346

wires were grounding out

[CB7Man]

Happened to me too
Just my rear speakers grounded out and none of my lights worked

If they are stock speakers though, I'd just replace them lol

[storm trooper]

my passenger door does the same some days it works some not if you have the stock speakers honestly those things are old so of course theyre going to go out eventually thats why im not worried about just an excuse to upgrade is how i look at it

yes if u still have stock speakers then yeah replace them please .... that alot of years on speakers that are made of paper. also i would like to have it explained how holding a 9v batt on ur speaker for a long time will damage it???

Do you have the OEM headunit as well? While the original speakers are showing their age, it still sounds like a HU problem.

Did you swap the speakers to see if the problem remained with the affected channel or if it moved to another one?
