Is it possible to make bluetooth speakers & jack speakers play simultaneously from android phone?

the answer is no, when you plug in a jack connection it tells the phone you want all outgoing sounds (phone and music) to be going to this wired device. Bluetooth will turn itself off.

... I moved subwoofer to another car but i would like to have still good music in the first one. So 1. option... and it´s to buy cheaper subwooofer (I don´t want to spend much money)... I have at home many speakers and subwoofers, so idea was to connect subwoofer and 2 normal speakers through voltage converter to car. Then I could play through it but car speakers wouldn´t work...
Sorry for my bad english, i hope you understand....

So only option is to buy car subwoofer, right?
