Tweeter switch questions

[novasak]

I dodn't know what section to post this, but I figure its a trick (for me).

In an Otop or DR:
Whats the best way to install a ON/OFF switch for a CD tweeter? The same place the L-Pad would be?
also
Can I add a switch to use fullrange and a biamp mode, not just ON/OFF?

These are some questions that I cannot find in older posts. But there have been so many other questions answered just from reading these threads, thanks everyone.
