serious problem with wiring for sub and amp,, help..

[chris060685]

wired up a sub and amp in my ibiza but it doesnt work, the green light on the amp isnt lit, ive been told its the earth wire??? where do u put it? ive tried the rear seat bolt? but it wont work? do i need to disconnect the battery..

Check the earth, make sure its contacting bare metal of the bodywork, also check the positive is connected OK. Also - have you connected the 'Remote' cable to the headunit or a 5v supply?

 

[chris060685]

ive connected the remote cable, and the connection to the positive of the battery is fine, ive tried the earth on bare metal but no green light. i cant see what else i can do? does the battery need to be disconnected before the earth is attached on bare metal?

 

[CHR15B]

I'm no expert, but its always something I'd recommend.

As said in other post, you should maybe check the fuse on the amp.

 

[chris060685]

fuses r ok, because the red light is lit on the amp, so it is getting power from battery?

 

[CHR15B]

Perhaps check the remote wire?

 

[chris060685]

checked it its got a wire from head unit with a label saying rem.ok. but theres one that says p.cont? which is also blue????? maybe connect it to that one instead?

 

[CHR15B]

I would have thought "Rem" would be the correct one... you might want to check with one of the experts on here... I've only done the basics myself

 

[chris060685]

who r the experts? lol

The manual is your friend, it will tell you which wire is which. p.cont could be an amp control if it's a kenwood HU and that definatley is the wrong wire to try and use.

 

[chris060685]

it is a kenwood heat unit, so its ok connected to the rem wire? and not the p.cont?

 

[truCido]

try looping a bit of wire over from the battery positive on your amp to the remote and see if that turns it on....oh and p.cont is the wire you need

 

[Icecavern]

Having just checked yes I agree p.cont is the wire you need. I was thinking of another wire on the kenwood kit that is used to control the powerslide function on kenwood amps.

just tried that and it still dont work??????? its not a dodgy amp as ive took it back, this is the second one? maybe the wiring is shite!!!!! is there anything else i could try?

 

[truCido]

ok if that doesnt work then I'd say theres something up with your earth, where have you connected it?
