Jensen uv8 sub works with radio an dvd but not with cd

Quiero instalar mi dvd car radio y violar el codigo de parqueo se que hay opciones para poder estar el vehiculo rodando y poder verse el dvd gracias

It could be that you connected the remote wire to antenna wire in the back of the stereo when you do this on a regular cd player (no dvd) only the radio will work because the antenna wire is hot so the amp turns on but when you switch to cd the antenna wire is not hot so the amp turns off

the antenna wire and remote wire are very similar lookin both are blue but one will have a white stripe try switchin to the other wire and see if this helps

Go into the settings when you are playing a cd and then go into the audio tab. make sure you have subwoofer on and the proper settings for it set. This is all I can think of.
