Adding an External sub-woofer to Bluetooth stereo speakers

[sydney]

Hi

Was thinking of adding an unused car sub-woofer to a pair of Bluetooth stereo speakers (2nd bedroom setup). Is this possible if I add an external desktop amp (with sub output); however the amp would have separate outputs for each channel and the Bluetooth speakers have one input for 3.5mm (in master-slave config). Any pointers would be great along with a desktop amp which supports this.

It depends if the car subwoofer is powered or passive and if the external desktop amp that has sub out is actually having a power out in sub or it is just a sub pre-out. You need to know both of these points to use them.
