Okay I have done plenty of aftermarket sub/speaker/amp installs. But never one with a factory deck. Without taking out the deck can i find out if there is a pre out for it, or is there something to buy that converts that for me. BTW this is a 2006 Dodge Dakota w/o the "infinity" system. I just would rather keep the stock deck in there to avoid theft and other reasons. Any how I just thought i would ask. Thanks guys you're always very knowledgeable.
