Crossfire CFA602, 3 Channel Mode Wiring

i have a couple questions for the audio gurus lol. i have a crossfire CFA 602 Amp and a Alpine Type S 1041 sub.  the manual is kind of vague.

amp info:

watts: 150x2 600x1

2ohm stable

sub info:

alpine type S 1041 10 inch SVC

watts: 600 peak 200 nominal 4 ohm

here are the images from the manual:

my question is this,

1. in the 3 channel mode (1st illustration) with the sub hooked up bridged and two 6x9`s hooked up normaly how many watts will be going to the sub?

2. how many to the other two speakers? 

3. will the ohm stay at 4 for the sub?

4. where would i set the crossover switch (2nd illustration) in the 3 channel mode?

is running a sub and two 6x9`s in the 3 channel mode as per the 1st illustration even feasible?

any help for the audio challenged would be appreciated.

1. 600 watts rms (this is a big old amp)

2. 150 watts rms to each other speaker

3. yes

4. it must be set to full range.

Yes it can be done and has been done properly for years. You will however need to construct a passive crossover for both the 6x9" speakers and the sub to limit the range of frequencies that each are going to play.

the specs in the maual are:

RMS Power 150x2

maximum power (mono) 600x1

THD 0.08%

bandwidth:  5Hz to 38KHz

signal to noise:  >100db

damping factor:  >300

seperation: 68 db

input sensitivity : 190 mV-5V

input impedance : 20 Kohm

power fuse: dual 30 amp

CROSSOVER

lowpass: 70/100 Hz

highpass: N/A

x-over slope: 12 db

45 Hz boost switch: yes

what if i were to only run the single sub off it? how would i wire it ? i assume that bridging it with no other speakers hooked up would be to much for the alpine sub to handle, am i correct? if i run it as per the illustration in 3 channel mode could you point me in the right direction to get crossovers for the 6x9`s and the sub.  thanks for your time guys. hope im not to much of a pain in the ass lol
