I have the infinity sound system in my dodge ram with a 10" sub under the back seat....I took the infinity out and modified the box to fit my JL 10" w3....can the factory AMP power this sub? If so, how do I wire the sub to work off that amp harness? The sub is a dual 2ohm voice coil and the factory wire harness has 2 connector with a green and black on each connector..........How would I wire the sub with dual voicecoils working and the factory amp to push it???
