single supply subwoofer low pass filter design

[motronix]

I am using this one:

if you are using this schematic with my low pass filter don't use the input capacitor C1 (short it) and increase R1 to 1K

I don't see what you mean, the output of the filter connects to the amplifier input and ground, how does the supply figure?

If you use a dual supply filter, use supply gnd for vcc-, and pin 14 as new ground for the filter.

Do you mean use the same power supply? Ground is pin 14

That's fine, is that what 4real was saying?

I will do that, Thank you so much for your all out support and advice.
