Car speakers crackle above certain volume?

[chezwez123]

Hey guys, today my car sound system has started playing up, I have 4 side door speakers, 2 6x9's and a 250W subwoofer, the subwoofer works fine and if I fade all volume to front speakers they work fine, but as soon as I put any volume through the rear speakers they crackle like mad even at quite a low volume, but the sub works fine.

Any help/advice appreciated

Thanks,

Could be that the 6x9s are working against the sub try turning the sub off and see if it still does it.

just tried that its still happening :S :/

Hmm one of your speakers has probably had it then mate.

speakers will be dead. or, check to make sure you're +ve and -ve wires are not in contact in the slightest on all your speakers.

run it off the rear speakers?

 

[chezwez123]

ok its only when i fade to the rear right it happens but i have tried removing the speaker and it still happens even with a working speaker, as soon as I fade to the rear right at all, every speaker except the sub goofs up .. >=/

head unit, or again, make sure your wiring into the head unit is clean/seperate and nothing is making contact with wires

are the four door speakers running off a head unit? what is powering the 6x9s and sub?

 

[chezwez123]

the sub is powered through the sub output on the head unit and wired to battery etc, and the door speakers and 6x9's are running purely from the head unit

that is a lot of power. what head unit is it? double-din?

 

[chezwez123]

its an alba of some sort, got a new pioneer radio arriving tomorrow anyways so i will see if it is the head unit, although i have run that set up for about 3 months with this being the first problem .. :s

Alba head unit?! Will defo be the head unit then! Anything Alba lasts 5 minutes. Didn't even know they were still going!

 

[Just Plain Yates]

you can only run four low power speakers off ANY headunit. so your alba (and new pioneer) is being over loaded, hence the crackling. this is the setup you need.

I am just confused as it is only the rear right that is causing it... i tried a radio out my mates car just now and it is the same problem so obviously wiring problems, so my question now is.. will it be the wires running to the affected speakers causing the problem or could it be anything? PS also the sub doesnt function when i fade to left only when it is faded right

 

[chezwez123]

problem solved, wasn't earthed properly.. novice mistake
Thanks for the help!

:S do you mind posting pics up of your system and dont you have any amp running atall?

 

[Addicted]

Sounds a bit dodgy running all that off the headunit to be honest, get an amp!!

 

[chezwez123]

I have an amp for the sub only, 6x9's and side speakers wired to rear output of head unit and two side speakers wired to front output of head unit, I will put some pics up tomorrow

 

[MT AUDIO]

Thats your issue, you are running too many speakers off the rear channel

Dis this kind ofthing myself to a Sony headunit I had, managed to blow the internal amp in the end after having it running for too long. Felt behind after removing it and the headunit had managed to melt some cables too because it got so hot. Safest bet is to get an amp to run some speakers off too
