I should have bought Technic's harness to save all the troubles.
Focal 100KRS 4
Focal IFBMW-SUB 8
Focal Impluse 4.320

Thanks for any inputs!

First, a few questions:
- Where is the Focal amp in the signal chain if it is only driving the subs? I ask because the HU does not output bass-only frequencies; only 2.0 stereo front L/R and rear L/R channels. If you're driving an already amplified speaker-level signal, that's far from ideal and can potentially damage those underseat drivers.
- I assume your 100 KRS set is in the front. What are you running in the rear? Another 100 KRS set?
Your easiest path is going to be to add a four-channel amp to drive the KRS set(s), or -- and this is what I would do -- remove and sell the Impulse and replace it with a six-channel amp such as a Focal 6.900.
