I'm building a bluetooth speaker, but I'm not satisfacted with the low frequencies, so I decided to add a subwoofer. At the moment I haven't decided which subwoofer exactly, but I'll will be a 4 or 8 Ohm one. Here is a list of my current components:
- Amp - TDA7492
- Speakers - Visaton FR 13 (x2)
- 12V 12Ah Battery
Even if the sound is not optimal, what's the best way to connect the subwoofer by having only 2 channels? Is there any way to make the subwoofer receive signal from both L and R? I assume my idea is probably wrong, but is it possible to connect them like this? The subwoofer is the bigger box. Any help is appreciated.
