Aftermarket head units and the Shaker 1000

you will lose the pair of 8's in the doors and the subs in the rear. You CAN use the preouts on the N-2 and splice in rca connections on the factory amps at the signal wires and this will get them to function again. I would recommend the N-1 over the N-2 though if you will be using the front screen for dvd's since you cannot bypass the unit to allow them to play while you are driving. I myself had the shaker 500 and am still using the factory system with the addition of the panasonic vcqd7001 flipout and its working alright until all my Kicker pieces get here. hope that helps
