Below is the suggested wiring update for the bridged channel. The following net connections will be applied:

ConnectionNet Connection DetailsComponent References
Signal Input Routing:- Connect the audio signal (input net) to one end of the coupling capacitor [C1] (4.7 µF). - Connect the other end of [C1] to the non-inverting input of [U1].Audio Input → C1 → U1
Decoupling for U1:- Connect the +12 V supply pin of [U1] to one terminal of the decoupling capacitor [C2] (100 µF). - Connect the other terminal of [C2] to the Ground net.+12 V of [U1] → C2 → Ground
Decoupling for U2:- Connect the +12 V supply pin of [U2] to one terminal of the decoupling capacitor [C3] (100 µF). - Connect the other terminal of [C3] to Ground.+12 V of [U2] → C3 → Ground
Bridged Output Connection:- Wire the output pin of [U1] to one terminal of the load (bocina). - Similarly, wire the output pin of [U2] to the other terminal of the load. - This ensures that the load is connected between the two output nets (which are out of phase).[U1] output → Load; [U2] output → Load
Common Ground:- Ensure that the ground pins of [U1], [U2], [C2], and [C3] are connected to the common Ground net.All Ground pins → Ground
All connections should follow the biasing/feedback network as indicated in the TDA2003 datasheet for optimum operation in bridged mode. Once the net connections are updated accordingly, your bridged amplifier channel will have:
  • A coupling path for the input signal via [C1].
  • Proper +12 V decoupling for each chip via [C2] and [C3].
  • A bridged output configuration with the load connected between [U1] and [U2] outputs.
You can now use the Apply changes button to update your schematic with these net connections.
