I hate to make a new thread for this because I am sure if I search for the next 30 min, I could find it...
Anyway, where/what are you guys who have factory option headunits hooking up your amp remote wire? I have the Alpine unit and can't figure out where to put it besides taping a fuse. I appreciate any help you have.

 

I haven't bought my subwoofer and amp yet, but the remote wire (which is normally blue/white on aftermarket decks) is a white wire located at pin #9 of the 10-pin plug on the factory decks.

And the wiring diagram sticky for reference:

Thanks dude! I was on my phone at the time. I am going to try and tap in at the underseat amp so I dont have to go all the way to the HU. Hopefully there is only one white wire!

 

Thanks again dm1336. I got her all hooked up. Had a hell of a time finding a good ground in the back area but I figured it out. Sounds pretty good for a $80.99 with shipping, Ebay special 10in sub, box, amp and wires. I will not wake the dead but it is exactly the "little more" thump I was looking for.

 

Nice! Glad to help

 

So I should be getting my new a sub and box in tomorrow where is the best place to hook the remote wire in?
