pre-amp out to sub-amp (BD-Design)

Hi,

I redrew the character diagram below with "^" to stand for "space", or else it doesn't align right.

Instead of:

Q1.
A)
Input signal -> PreAmp -> Amp1 -----> Oris Horn
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^|--> line filter -> Amp2 -> base woofer
(i.e. line filter in from Amp1)

Can I do:

B)
Input signal -> PreAmp ------> Amp1 -----> Oris Horn
^^^^^^^^^^^^^^^^^^^^^^^^^|-> line filter -> Amp2 -> base woofer
(i.e. line filter in from PreAmp)

For case (A), it seems to me too high a signal level is to Amp2 as it's
the output of Amp1.

Q2.
For the Horn driver, I use 8 ohm; do I have to match the base driver to 8
ohm too?

THks
Francis
