Radio has no sound
I had a problem with my Stock HU a few months ago when it just stopped working. no sound whatso ever came out. it was fully functional, but no sound. the cd player took in cds, the clock worked, but no sound. i thought the radio just died. but every once in a while it would give out sound for 10 seconds. and not play again...
which brings me up to today. i bought a Alpine CDA-9856. i wired up the HU to a conversion harness. I wired everything correctly...(ive done a lot of installs)
I first turned on the HU and there was sound!!!, but that was short lived and it didn't play anymore sound...
THen i thought it was the ground... I grounded the HU to a bolt under the radio and there was another ground connected to it...
Still no sound...
This **** is driving me crazy!!!

yes they would.
You have a short somewhere. Check where you have all the speakers connected. Yours speaker wires are touching somwhere. Check the 6x9's first since theyre easy to get to. As soon as you untouch the wires, youll have sound again.
If one speaker stops working, the other 3 will still work just fine. When you swap out speakers and install aftermarket ones, chances are the wires will touch together if you dont put the proper connectors on since theyre already really close as it is. When they touch, all the speakers will stop working.

Wrong. A shorted speaker will cause the other 3 to not work, a blown speaker the other will still allow the other 3 to work. I had one blown one when I changed out mine a loong time ago and the other 3 worked perfectly fine.

Rep Power: 263 My question is: Why will a "shorted speaked ... cause the other 3 to not work, a blown speaker the other will still allow the other 3 to work."
In post #6, you referred to a short as being two speaker wires touching each other. This is one definition of short, the most likely other being a short to ground. My other question is what do you define a blown speaker as being? The most common definition I know involves a melted voice coil that is shorted to continuity. Pretty much the same thing as your 'short'.
An aftermarket deck with a blown speaker will cause the amplifier's built in protection circuity to stop all output completely so as not to damage the deck. An installation short or short to ground will do the same thing but is likely to be intermittent, not all the time as in this case.

Rep Power: 403 BLow: others will work(i have seen this with my friends 15 year old POS car)
shorT: none will work...
alright, i think i know which speaker it is... i don't want to take my stupid door panels off... i already checked the rears and they are fine..

Rep Power: 263 The kind of blown speaker that would be more like what happened to spoonem would be a broken speaker, one where the lead had come completely disconnected or something to that effect. It, of course, wouldn't shut the deck down as it would present infinite resistance as opposed to none. However, that's not the case for HondaLuver.
Luver, pull your deck out and check the resistance at each set of speaker wires. Further investigate any deviations from about 3.5 - 4.5 ohms per speaker.

Rep Power: 403 i had a accident a little while back, drivers side, and they replaced the whole door skin and side of car. i was having a problem with the window after it was fixed. he had to pull out the speaker holder because the window would lower on the magnet. and when i turn on the radio, i head a little sound from that speaker...]
problem looks like its solved. i'll mess with it tomarrow morn..

Yeah...its probably just 2 wires that are touching. That should fix your problem. Hope that helps.
Racism sucks, just like your Mom...

Rep Power: 263 Allow me to sum it up.
Blown speaker with resistance = 0 (internal short of voicecoil):
Shuts down amplifier output of aftermarket deck for all speakers.
Blown speaker with resistance = infinity (broken lead, etc.):
Doesn't affect output of other speakers, obviously doesn't play music itself.
Short to ground in speaker wiring or short of speaker wires to each other:
Shuts down amplifier output of aftermarket deck for all speakers until short is repaired.
The last one tends to be related to installation error and is usually intermittent. The fact HondaLuver's problem wasn't intermittent led to my diagnosis of blown speaker, which appears to have been the case. Another thing to take away would be there is more than one kind of blown speaker.
There was a short in this system, it was in the speaker itself. I think most people would classify that as a blown speaker, not a short. Either way, bad speaker.

thats when they are being grounded and ur wrong the only time its being grounded its when none of the speakers work at all.

Thats an excellent way of explaining shorts/blown speakers. +1 for you.
