ok i got my head unit working and i went to check some thing and i saw a spark some where....it blew a fuse i replaced it and now i get the sound of the speakers comeing on but no music comes out... is there some wrong with the amp in the car? im not very good with audio systems so if you would help me out that would be awsome

WOW that sux. Best bet is take it to a shop to ensure you get proper guage wires for your application and so on.

But first thing to do. Unplug the +12v from the amp. Now are you shorting or back feeding? If you are not then the issue is within your amp wireing. If you are then it is in your head unit wireing. Pull the unit out and trace over all your work or return it to factory and asses then. The best thing is to back trace your work and asses out of proccess of elimination.

lol well im just trying to install a head unit .....its a pioneer from like 1995.on the factory harness side i have the aim wire (white and red) hooked up to my 12v switch wire...factory harness side is (blue and white) i beleive. where should that amp wire be hooked up to ....what happens if i accidently touch it to a ground wire? what happens when i accidently touch a speaker wire to a ground wire?

skatingsamurai

oh and when i unplug a the amp from the 12v the stereo wont even turn on

What type of amp do you have? is it a built in amp into the head unit you are refering to or a standard amp? It sounds like you did not hook it up correctly.

If you ground a + wire it will spark and if you ground it long enugh it should blow a fuse or melt if inproper fuse is used.

Speaker it wont do anything just wont work. But in some cases such as seriesing subs to 1ohm from dule voice coils on a mono stable amp you can do something like that.

"from FAQ by icemark"
What are the wire colors for adding aftermarket radio
LTBlue/Red= 12v+
LtBlue/White= +Accessory
LtBlue/Yellow= -power ant trigger
Red/Black=+ Lumination
White=Factory Amp Turn on

Ground to the body, use the 10mm bolt behind the center console front drivers access panel. Do not use the Red/Black as ground it will damage the interior light circuit and dimmer in the car

Front Speakers (maximum of a 15 watt peak from the radio):
LtGreen/Red= Left
LtGreen/Black= Left

LtGreen= Right
LtGreen/Yellow=Right

Rear Speakers (if applicable, if you have the amplified rear speakers again the Maximum of 15 watts peak is all the stock speaker amp input can handle):
Brown= Left rear
Brown/White= Left Rear

LtBlue= Right Rear
LtBlue/Orange=Right Rear

skatingsamurai

i hope i diddnt ruin anything

iceblue

To + on head unit
LTBlue/Red= 12v+

Most aftermarket units get lumination from the +12v

self exsplanitory
LtBlue/White= +Accessory

Should go to any + out put on head unit such as remote
White=Factory Amp Turn on
LtBlue/Yellow= -power ant trigger

Ground to well ground

Check all fuses under dash panel and replace as needed.
