basic wiring problem but i'm clueless

[GT-Swhite]

i had been using the ta03 mod to a jvc head unit until i replaced the amp entirely to power a new set of components. that worked fine for a while until something caused the 12v constant wire from the harness to die out. i know that is the source because once i piggybacked the wire from the head unit to the amp's power wire, it began working again. that worked for a week or so until i went over a speedbump and something caused the fuse on the head unit to go out. thats the back story, and my question is:

how do i regulate a wire coming off the battery to 15 amperes so it doesnt blow the fuse on my head unit?

any help would be appreciated, i went a whole semester without music and cant do it again

well, i dont know how to regulate your wire(some kind of resistor?). But that fuse you blew from the harness 12V source is one of the large multi fuses in the passenger side kick panel. It is up at the top of all the other fuses and brown. Its as long as 4 mini fuses. At one time I had blown two of the 4 paths within the fuse and my clock and cd player didn't work. But for a long while, my cd player was jump wired from the fusebox on a piece of scrap wire like you had.

in my gt-s I have 2 sets of components on a amp, and then the sub on a seperate amp. Off the back of my cd player, I have the following hardwired into the stock harness:

-Ground
-IGN
-Mem
-Rem

then i have the antenna and rcas coming off the back. To me it sounds like you have the same setup, so why the TA03 harness needed? BTW I have JVC unit also.

hopefully you can find that blown fuse and get your tunes back.

If you're blowing a fuse, its not because the battery is pushing too much current, its because something is drawing too much current. You could hook up a 1mA device to something that supplies 100A and it wont hurt it because the device is only drawing 1mA. 100A is simply the maximum potential of the power supply.

Check for faults in your wiring. If you went over a speed bump, a wire could have touched another that wasnt properly isolated (accidentally nicked the plastic, melted off too much, etc) and shorted out, causing the fuse to blow. They dont blow for no reason, check over your wiring for a bad wire.

thanks for the replies, im gonna check the interior fuse box tomorrow and hopefully that will be the original problem that im *****footing around.

i had the ta03 originally because i first just wanted an mp3 player, but after a few months the audiobug burrowed into my brain and out came new components and the bypassing of the stock amp entirely.

and about the faulty wiring i assumed that first, but am still getting to the bottom of the speed bump thing cause it must be a nick in the jacket or something cause the connections themselves are isolated. ive hooked up the cd player straight to the battery (14 awg)and still the fuse goes, so i guess get a better ground?
thanks again guys
