Well for the antenna, just extend the trigger wire from the deck or if it has an antenna turn on wire from the deck extend it to the antena should work.

With regards to the static, when do you hear it?
Could be a ground issue...
I would swap out the speaker wires from the front to the rear to see if it's the deck or if it's the speakers.
Good luck buddy.

It's easy to add a ton of equipment yet it's most difficult to make a great sounding system with less.
