I just installed a deck, there was no stereo in it when I got it. It sounds terrible, there is obviously a factory amp that's got to go. I was hoping there might be some wiring diagrams for the amp bypass. It would be nice to find something before I dig into this.
Anyone have any experience with vehicle?
Thanks in advance.

Thanks. I couldn't find anything on an amp either. I'll have to ohm out the speaker circuits. It starts crackling and sounding terrible after about 15 minutes then after a little while it will stop making sound altogether. I thought it was the cheap Blaupunkt deck I had put in. I swapped it out for a less cheap Boss unit, same issue. It does have a factory sub.
