I had purchased a set of Focal Utopia 136W a number of years back that were installed for me in my 96 Maxima. They were coupled with an Xtant 604x amp all purchased from a shop. Now I got a 2010 Camry SE and decided to move the speakers over to this new car. However, I also have a set of MB Quart QSD 164 midbass add-on component system. I wanted to know what would be the best wiring diagram to squeeze out the most power out of the X604. I would prefer to use just the 2 front channels but will use all 4 if its a drastic difference and an absolute must.
Here are the specs for the Focal 136W
2 way component system that supports bi-amp
non powered, 70W RMS/ 140W Peak
Freq Response 100Hz-22Khz
Sensitivity 94.5db
The terminals on each Xover are as follows
I- I+ W- W+ O- O+ T- T+
I = Input, W = midrange woofer, O = "option", T = Tweeter
The specs for the xtant 604x are:
Freq Response 5Hz to 50Khz +/- 1db
Number of Channels 4
4x75 @ 4 Ohms
4X150 @ 2 Ohms
2x300 @ 4 Ohms
Recommended load >2Ohms stereo/ >4ohms bridged
This amp also has RCA line outputs for each channel
The manual for this amp is here

Page 7 has all the specs for this amp
The specs and terminal diagram for the QSD 164 xover is
4 ohms per speaker
90w rms/170w peak
sensitivity 85.5db
freq response 35-280Hz
Terminal left - right are as follows
LI- LI+ LS- LS+ LW- LW+ RW- RW+ RS- RS+ RI- RI+
I = Input, S = to focal Xovers, W = Midbass woofers
Heres a link to the Manual of the QSD164

Page 7 has all the wiring diagrams for this midbass component system
Currently im wired amp 1ch >> midbass cover >> focal xovers to midrange/tweeter... Is this drawing 2ohms 150W or 4Ohms 75W from my amp?
Thank you in advance
