666, to be honest, I can't think of anything at the moment. I am thinking it has some relation to your turbo timer, maybe in the wiring.

I am in Auckland, and would be happy to check it out. I work out West, you can pop by any time and I can check it, alternatively I could look at it, at our next Saturday night meet.

email me

In the mean time, I will keep thinking :)

k, thanks GSR32. I'll prob come 2 next Sat night meet, depends on how the study for exams goes this week.:splat:

Well cecam, wots basically happening is when my car has been running & I turn the ignition off and remove the keys till the t/timer goes off, then when I go back 2 the car later and start it up or even just put ign on acc pos no sound comes out of speakers except tha sub. I need 2 turn tha stereo off and back on for it 2 work properly. It seems 2 only do this when I have the t/timer on tho.

just a wild stab but it sounds like your turbo timer
is running off the same power supply as the head unit?

when you start your car the turbo timer pauses to turn
on as it remembers the preset time you dialed in.

the yellow wire (constant power)is what controls all
the functions and the red wire (acc) just turns the unit on and off.

so when you turn the key on it turns the unit on and your amp,seeing your amp has power straight from the battery
the sub will go.

so it sounds like the turbo timer is tapped into your
yellow constant power line.
the amp in your unit will need constant power to run the speakers.
just try giving your timer a new power feed :)

or you could just getr the shop to look at it :D

:devil:

ummm, yeah, good guess Evil, I still can't see that being the reason. The amp requires the remote signal also, in order to power up and operate, and this comes from the remote ouput of the head unit.

The remote output does not go to +12v until the head unit fires up and recieves the acc +12v.

Now, if the timer was connected to the acc line, it wouldn't make any difference to the operation of the head unit. The head unit must be recieving it's acc +12v and a permanent +12v supply, because it is firing up and turning the amp on.

666 - if you can't see anything, I am still happy to check it out. I really need to see the wiring etc

GSR32, that may or may not be the case.

Someone I know has a Pioneer headdeck and the remote output doesnt work.  So I jsut hooked it up to the accessory line instead.

It means the amp is always going when the cars going, but who cares?

Arithon, yes, but no in this case.

666 has already told us that the remote turn on for the amp, is coming from the head unit :)

make sure you have ah fuse on your new power line :)

when its hooked up in the car it runs though the fuse box
10 amp i think,then though the fuse that comes with the unit.

just match it up with the one under the dash :)

solved,

666 would turn on the unit and the amp+sub would work
because.
the amp only needs acc to turn it on as it has its own constant power supply.
the rca outs are not part of the pre amp.
the head unit would turn on because that only needs acc to
light it up and work functions.

the speakers would not work because the pre amp was not working cause the turbo timer was breaking the power circuit.:)

Very strange.....most head units that I have worked on, require both permanent backup 12v (normally yellow wire) AND acc 12v (normally red), to even light up and work.

What brand and model head unit did you say it was 666?

it's 1 of those panasonic ones which is silver & lights up blue/purple in the dark. CD/tuner.:)
I've found with a previous head unit if I remember right tht I only needed acc power for it to work, the only thing it couldn't do was remember stations, position on CD it was last at etc..
