Installing sub woofer

Hey,

I am quite pleased with the infinity stero system in my 2003 Altima however I have purchased a custom subwoofer enclosure (ebay) a mono D amplifier, and two 10" subs. I'm wondering how I should wire it. Can I tie into existing wires running to the back speakers and feed that to the input on the amp, or should I wire it from the deck? Any suggestions on how to route the power wire to the amplifier? Appreciate your feedback.

IF IT IS THE FACTORY RADIO YOU NEED TO BUY A LINE OUT CONVERTER CAUSE THAT IS HOW I HAVE MY SYSTEM HOOKED UP ,SO YOU WOULD CONNECTED YOUR FRONT SPEAKERS TO THE LINE OUT CONVERTER AND THE REMOTE WIRE TO YOUR FACTOR POWER WIRE OR A POWER WIRE THAT WORKS WHEN YOU TURN THE CAR ON YOU CAN BUY THE IN LINE CONVERTER AT BEST BUY OR A PLACE THAT SELLS CAR AUDIO EQUIPMENT
