I later came up with an idea to solder 1/4” connectors to those speaker wires feeding to the sub, and instead feed them into the BFD’s inputs (the higher level shouldn’t be a problem – I can switch to the 4 dB setting if needed).
I'm surprised the level wouldn't be a bit high for the BFD. Even the +4dBu setting assumes a maximum input of only ~4.9vRMS and nominal of ~1.24vRMS. Your woofers max out isn't more than 4.9volts? That would only be ~3 watts? I guess the BFD's input LED's will tell you that pretty quick though.

Even then, I would have thought the M&K sub would have wanted a consumer level rather than a level consistent with the +4dB setting. The -10dBV setting would assume a max of 1.25vRMS and a nominal of 315mvolts.

Are you sure you don't need to attenuate the level with a divider?
