Durango 2005 Hemi
 

Ok my brother in-law just purchased an 05 Durango and he want me to upgrade the factory system in it.

First thing, when i opened the hood i got a BIG surprise... this engine's HUGE!
So the question is where's the best place to go thru the firewall?

Also is there anything special when replacing the factory HU, or it's just the basic metra kit+harness+antenna adapter?

Thanks
