Sounds like you have a lose connection. I'm guessing you, for example, knocked the ISO connector on your headunit and now it's come adrift enough to cause you to lose your speakers.

I'm assuming your speakers are unamped.

 

Need to know your configuration. Is it one sub per amp? Or one amp for speakers and one for subs?

Are all speakers connected to same amp / to the head unit?

When you say "everytime you slowed down" what do you mean? Reduced speed?

 

Yes they are normall speckers. But i can not hear any clear sounds out of subs. When i start bracking and slowing down for some strange reason the speckers all go and you can only hear bass from the subs then you let of the brake and speed up and its ok. But now its gone all together all you can hear is bass. im running to subs with 2 amps. and there is no amp on the speckers.

 

sorry dont know what the ISO connector is. Ive checked all the connections and there all fine. I do not get what could be wrong

 

where abouts are you from?

 

Kent, maidstone. by the way thankyou for all the people trying to help me by the way.....

 

your sub sounds fine, i think it could be something to do with your loom, it defo sounds like a power issue as your charge is dropping with your speed, dodgy loom, or iso connection i dunno this is a strange one

 

needs ripping out from headunit back and starting again.

 

dodgy adaptor if your using one????

 

But it was fine when i stopped it was just going funny when i started to slow down . But now it doesent work at all. its weired.

 

ive only got a adaptor to the cd player. but some of the wires have clips on them if you get what i mean

 

So was it ok before you put the subs in? Does it work ok of you disconnect the amps?

 

Yes it was fine before i put the subs in. plus it was working fine when i had them in for 2 weeks. then after that it started to play up. no i havent tured the amps of should i try that

 

i dont think its got anything to do with your subs as they are seperate and nothing in and around them is goign to your speakers, i think its definatly from your headunit loom back to the power source.and if your speakers have now gone alltogether i can only imagine its to do with your speaker wiring and anything that goes to it maybe a fuse or a short im not sure im not a car electrician but i would rule out the subs

 

ok well the cd player plus subs work. its just sound from the speckers plus clear sound not just bass from the subs. so what do you think i should start checking first. I couldint thankyou so much for helping

 

find a mate you can swap headunits with

 

I'm thinking maybe some sort of power issue. If the amps are disconnected it will be a good place to start narrowing down. When you say all you can hear is bass from the sub, do you mean continuous bass, like interference, or the bass notes of the songs you're playing?

Does it seem to be affected by volume? Does it happen if the system volume is quiet?

 

the bass is the same like it would be for a song. plus you can hear a slight singing of the song. but not close what you should be hearing from the singing about 20%

 

Aah, I was thinking interference-type sound from your subs.

In that case, I suspect head unit fault. Any way you can get it in a mates car to check? Or borrow one to put into yours?

 

maybe is that what you maybe think it is then. but i do not get why it was doing that before when i was slowing down. plus i can hear a little music from subs. its weired i do not get it

 

You can probably hear a little music from the subs because the crossover isn't totally filtering out the higher frequencies. The head unit sends the full sound (frequency range) to the amp in the boot and it's the amp's job to filter out anything the subs can't play.

I don't fully get the slowing down issue. Only thing I can guess is that something in the head unit was on its way outand reacting to power changes. Now it's completely nackered and you can't hear anything.

Did volume change make any difference? When the system was quiet or loud?

 

yes before it went all together i couldint put the sound up to much or it would do what it does when i slowed down

 

Definitely think it's a head unit problem, maybe output stage.

Best thing to do would be to try and get another one in your car. That way you can be 100% sure

 

ok thankyou for the help well let you know how i get on thanx so much

 

No worries

 

either get a new HU or an amp to power the front speakers to bypass the internal amp in your current HU which is probably causing the problem.

 

As the others have said it's either a wiring fault ( as I said initially ) or the amp in your head unit has died.

Personally I'm still certain it's a wiring fault because braking causes thing to pull towards the front of the car. If you've got a loose connection somewhere over time it would work lose.

He also said it did the same thing when he turned the volume up. But yeah, the braking thing is wierd.
