The mopar amps are pretty good, you might be better off using the mopar
amp. Look at the specs on your mopar amp and your headunit and then use
the one that has the lowest THD rating (total hormonic destortion) If I
recall correctly your speakers outs on your headunit would be used for
high output leads (sortta sux) I think you should cut the wires that go
into the input of the mopar amp and hook them directly to the speakers.
Leave the old amp in the truck though incase you decided to resell the
truck or something.
This is how we did it where I used to work anyways (car audio shop)
