I had a local shop install a new stereo, speakers, subs, and amp in my '68 vert. I copied Yellowbird's installation of the rear speakers...and used the Custom Autosound head and CD changer from CI and Ames. (If interested, I'll send photos and part/model numbers).I'm VERY happy with the results. Except...

The installer connected the amp directly to the battery terminal with one of those big @$$ "monster" cables...and ran it along the heater hose to the firewall. It has a 60 amp inline fuse. I do not like the way this looks. I want to re-route this power source within the radiator support and back under the driver's side fender. Question: Can I connect this wire to that "relay" that the smaller wire from the positive battery cable connects to?
