im installing a dvd HU on an eclipse and everything powers up fine and functions correctly besides sound coming throught the speakers. Someone had broken into my car and stole the HU i had before this and the cord right next to the antena cord looks like it might be broken. so thats one thing that could be wrong. Another thing i heard is that eclipses need have a stock amp under the passenger seat that needs to be bypassed or integrated. i have the correct harness to do that but am unsure how? any help is apperciated.
