I have a 2003 model as well and it was completely stock until last month. A cd was stuck in the changer so i used that as my excuse to upgrade. i bought the jvc KW-AVX800 and it looks and works really great but unfortunately it can't work with the oem ampifier, so now i don't have the extra "bang" that i was used too.(as least that's what the guy that installed it said). Though it did work briefly while we tested the new deck. sounded really good too but by the time we restarted the car it stopped
So as a noob, is there something we missed? replacement oem part that might work or do i have to go completely after maket to get really good sound?
By the way could you send me that wiring diagram too please?
My first post by the way
