[dave20089]

yeah but how do i do that though i can wire the rest just not sure how to do that part

[strgas]

run a wire from the positive terminal thru the engine bay thru the firewall and connect it to your stereo power supply wire dont forget a fuse at the battery , or use the live wire at the ignition switch loom ??? if in doubt have a auto elec wiring the power side for you ...

[dave20089]

oh yeah i have an old amp power wire there with a fuse in it that runs straight inside i can just hook that up th it n dont have to earth it out or does it just earth though the sterio .

[strgas]

connect it to earth without the stereo in line and it will short out , connect to your stereo power wire and the stereo earth wire to earth ??? simple as that

oh sweet sorry to b a pain just wanna make sure before i fry shit costs to much lol cheers

[strgas]

always better to ask questions first and look silly than go ahead and stuff it up completely

[holdenboy]

I would recommend just joining the yellow and red wires together on the back of the head-unit, its simplier and less dangerous.

May i ask why you would want to hook it straight up to permanent power? This is one of the reasons why the accessoires switch in the ignition was made.

i would personally find it very annoying to have to turn off the headunit manually every time i switched off the car.

there's a thread on here somewhere where a guy wired up the acc wire to a relay so the headunit stayed on until the doors were opened. that's about as far as i'd go

[axemurderer101]

how about using the constant feed from behind the headunit and use a switch which is wired to constant and accessories so when you flick the switch on with the keys out you can listen to your cd player

what's the difference between that and using the on/off button on the headunit though?

I'd just hook up a switch that bridges accessory power to 12v constant. When switch is off, it will work just like its supposed to (with key in acc/ign position), when switch is turned on, stereo will be working regardless.
