Accessory Power
 

I am stumped at the moment. I have read quite a bit in this forum regarding stero upgrade. I would not consider upgrading the HU if it could play MP3. Anyway, I just swapped out the dash speakers and am trying to replace the HU w/ an aftermarket JVC and also replacing the door woofers w/ a component set. I need haelp in locating the accessory power. Finding the contant power was easy but I could not locate the accessory power. Another question I have is whether or not I need to add an amp to power the door component (Sony Xplod XS-GTX1620S) or the aftermarket HU is enough.

BTW, I just finished installing an aftermarket HID (Riken which is made in Germany) and installation was quite easy.
