I too am looking to add some more bass to my system. I have 2-12" Hifonics Zeus subs to be powered with a Hifonics Zeus ZRX 1016-4 amp. I know that running the power supply will be tricky, but I am also looking to find info on removing the radio dash so I can run the RCA's without "making a mess". I haven't had any luck yet for the 2012 Z. I may have find a Lincoln mechanic or bring it into a car audio store.
