The left speaker’s SDA drivers are not moving. Right side is fine

How do I trouble shoot?

Thanks

    Test tone for left speaker will drive SDA driver on right channel, test tone on right speaker does not drive driver on left speaker.

    Should I start by swapping the drivers?

    Jesse, i swapped drivers and it’s not the driver.

    Still wouldn’t drive left SDA effect. Right still worked

    Thanks

    Ok, I assumed by not moving you meant the driver was locked up when pushed on by hand. Obviously, I was mistaken.

    So, the SDA driver is not getting a signal. That could be an issue with the SDA cable or the SDA socket or the crossover or the lead wires coming off the crossover.
