hd radio
kwazyliloboy asked:


I have a ‘04 Toyota Matrix with Alpine CDA-9885. I just ordered the Alpine HD Radio tuner.

I know the basics of how to connect it and an idea on how to run the wires, but do i HAVE to connect one of the cables to my cars Negative Battery Terminal? If i dont what will happen? Doesn’t look like theres any place to run the wires to the battery, unless theres room under the side door frame.

Also the grounding cable, could I connect it to any part of the metal frame?
I mean Positive terminal.
