Usually the remote wire is blue with white stripe that energizes to 12v
when the head unit turns on to signal the amplifier to turn on.

So, since the rest of the Bostig kit hasn't yet arrived, I decided to
install the new radio head unit and subwoofer I got from Crutchfield. I
noticed that there's a white and blue wire coming from the radio unit, and
according to Bentley (97.199) it would go to an "amplified speaker." Is
this a signal switch wire, which can be used to power on the subwoofer amp
by the head unit? Or does it serve some other function.

Any advise on that or subwoofer installation in general would be
appreciated. Thanks.
