Hey Eldgebroni, just trying to figure out the sound system wiring atm. I'm hoping to use the stock amp and speakers and not have to buy a new system. METRA 70-7551 might still work.. getting some mixed info tho.
Hoping to also see someone sell a 04 double din with ac controller while at it. If anyone has one let me know 
So far the 125W power supply seems to be enough which is good because there's a 120w dc source in the bin between the seats. If i can use that then it will make things a bit easier when im installing everything.
