Hi,

I am going to install a 'high-power' Alpine head unit that requires a direct connection to the battery.

Whats the best way from the battery through the firewall and to the head unit location?

Can this be done without taking the dash apart?

Any and all help is greatly appreciated!

Thanks in advance,
Karl

You can run it through the grommet behind the battery ( cut off one of the nipples and push it through)and then take the underdash panel down and you should find the wire there then run it to the radio.

Yes...unscrew the panel below the glove. Underneath you will see a gourmet. You can also see them behind the battery. YOu'll have to remove the plastic behind the battery.
