If I chose to get amp input from the speakers and connect it to the high level inputs on the amp, do i still need to
connect the amp turn on to something, or will it detect it on its own. The amp will be in a 1999 taurus, used to power
the rear speakers, and the HU is the stock oval cass. player. If i do need the amp turn on, where do I connect it
(no power antenna) ?
-thanks for the help (even though it doesn't have to do with contiques

)
