Amp wiring and speaker polarity

[TheG3]

How and where did everyone connect the remote turn on wire for your amplifier? Also can't figure out which wires are positive and negative for the rear subs. It's the Rockford upgraded system with rear 6x9 subs.

Aftermarket decks have a wire its blue with white stripe. If using stock radio, get it off the wire that has current when the key is to ACC position, use a test light to check.

For polarity check, apply 12v to the speaker wires it doesn't matter how. If the speaker pops out the polarity on the battery is correct, if the cone moved inward then polarity is reversed.

Thanks boss. It's the stock HU. So I don't have the ability to do that. I know I need to go to a fuse or something. Just unfamiliar how and which to choose for the turn on.

Don't do that fuse crap. It never fails to come loose. Pull the radio out and use its account wire or use the cig light outlet, Tap into the (+) wire of it.
