NEED HELP ASAP

[DaNiMaL]

Fitted a sub and amp earlier today was working fine, until suddenly, (YOU GUESSED IT) it stopped working...

Red protect light came up on my amp and the sub stopped working..

Every time i pull the two remote wires out the back of the headunit the light goes off then when i plug them back in they go back on again, the wires are not being pinched or anything, any idea whats going on?

I could be totally wrong but the protect light on mine was to do with the earth being dodgy, where have you got it earthed?

Sounds like a dodgy earth to me. It shouldn't be anything to do with the remote wire. The remote wire tells the amp when to switch on with the stereo. If the earth is dodgy, when the remote wire is plugged back in, it switches the amp back on, if a dodgy earth, the protect light will come back on again

the best earth will be a bare metal surface. NOT painted

i earthed it to a metal bolt where else is there to earth it? when i take out remote wires light goes off, when i put them in it goes back on

 

[coxxy]

remote wires? how many you got

 

[DaNiMaL]

2 each side.. double sided, 2 going into amp other side going into the head unit, when i remove the remote wires from the head unit the light goes off, when i put back in it goes on again, it was working earlier so i dunno wtf happened, cant be a dodgy amp.

 

[Bodge!]

I only ever had one remote wire?

 

[DaNiMaL]

yes its one.. sorry i mean its double sided so 2 inputs on each side.. one wire

 

[coxxy]

u sure its the remote wire (blue) and not the RCA leads (red and white)????

 

[SimonR.]

That bolt you earthed it to, did you wire brush it first so it is bare metal?

 

[DaNiMaL]

im gunna go check in the car now haha brb boys

Removing the remote wire will turn the red light off as that means there is no longer power going to the amp at all.

If you plug the remote back in, it will light up red (protection mode) as there is an earth problem.

What amp have you got? Ive got a FLI900 here that is constantly on protection mode for some reason, tried various earth points around the car and it will always cause a spark at the wire, dim the protection light for 2 seconds and then bring it back on again in protection mode.

if you got a multi meter with a current setting 99.9% have it

the way to find if it is a bad earth put the multi meter on current dc and make sure probe are in the right holes

switch head unit and amp on but turn the volume down so you can just hear it

then stick one probe on the - terminal on the amp then jab the other on some bare metal parts

then if the amp fires up it's definatly a bad earth connection
