TAS6424M-Q1: about optimal speaker connector and wiring

Part Number: TAS6424M-Q1

Dear expert,

We use TAS6424M-Q1 in automotive IVI application with a 24pin connector for PA output to speaker wiring. Due to the 3A current limit per pin for the connector, with 12V PVDD, 2 Ohm speaker and BTL configuration, the Irms through the speaker wiring under maximum power output will be about 4.2A, so I have to use two pin for SPK+ and another two pin for SPK-.

My question is that I am not familiar with speaker wiring in automotive application, if I have to use 2 pins for SPK+ because of current carry capability, which of the following wiring scheme should I use?

My second question is that if I am going to use one channel in TAS6424M to drive two parallel speaker, each impedance is 4 Ohm, which of the following wiring scheme is optimal (also take current carry capability into consideration)?

 

I know these two question is not very related to TAS6424M-Q1, but can you use your experience to help me to decide the wiring?

Thank you.

    Boqian,

    1. cable vendor usually use J1 solution. I am also not a cable expert, i don't know if any vendor can design a cable which has two wire shorted beside connector.

    2. Based on answer of first question, the answer would be as below. I think both works, but the up side one could be more reliable from cable redundant perspective.
