Considering the TI3255 in mono mode for a ripole OB subwoofer.

I am thinking of using a TI3255 in PBTL mono mode for a ripole / SLOB design. SLOB design consists of 2 Hertz 12" uno S300 S4 drivers.

Assume that the most likely thing is to parallel connect the drivers to get 2 Ohm on the amplifier? A bit unsure if the TI3255 has the possibility to drive this configuration? Is it correct to configure in PBTL mode or would it be more appropriate in 2.0 BTL? And last but not least, one TI3255 is enough, or do you need 2 pieces?

After some discussion with some HiFi friends, I have come to the conclusion of attempt using the TI3255 as 2.0 BTL configuration.

It is a bit extensive to rebuild the tpa3255 board, but it is now in default mode.
