Hi,
the 26r (or 27r?) on the output seems a little high.
And you should add the other half of the Thiele network to the the output so that the amp sees a high frequency load.
The passive single pole low pass filter seems a bit unusual.
It will let through much of the audio signal.
In fact the signal out of the sub will be quite intelligible the way you have shown it.

I have to agree with AndrewT about the passive crossover. I messed with them for quite awhile and never got rid of the spikes they allowed to pass.
Also, I just built a sub amp using an LM3886 and with the below active crossover, the thing peforms way past my expectations.
Edit: Your schematic does not show the mute resistor.
Concider this.

Re: mute
You don't have an option, it has to be connected. Leave the switch out.Jack Bruce said:I do not plan to use the mute.
