if i parallel 4 lm3886 driving a 1ohm load, then each ic would see a 4ohm load, am i right? what would be the disadvantages of this compared to bridge/parallel (BPA) config
another question,
what would be the best way of wiring a DVC sub, 2ohm each VC to 4 lm3886
1. wire the sub in parallel resulting to 1ohm impedance powered by 4 parallel ic, each seeing a 4ohm load
2. parallel 2 LM3886 and wire them independently into each 2ohm VC
3. the BPA200 config
any suggestion would be gladly appreciated, thanks🙂

None. BPA would need higher speaker impedance or you would have to parallel several BPAs.ryan750 said:
Your choices 1 and 2 make little difference. The advantage for version 2 could be that you share the current across two speaker cables, so you can use a smaller wire diameter.ryan750 said:
The BPA configuration can only drive 2 Ohm loads with a low supply voltage, and should better not be used below 4 Ohm.
How about wiring the voice coils in series? That gives you 4 Ohm and you could even try to work with a single IC. If you want to use more power, this is the configuration where you can use BPA.
