6 x 4 Ohm Speakers on a 2 Channel 2 Ohms Stereo Stable Amplifier

Hello everyone.
I got a Kenwood Excelon amplifier X621 which is:
2 channel and 2 Ohms Stereo Stable / 4 Ohms Mono (Bridged) Stable
179 watts RMS x 2 at 4 ohms
305 watts RMS x 2 at 2 ohms
612 watts RMS x 1 bridged output at 4 ohm
Then i got 6 speakers JVC CS-V527(200Watt max and 27watt rms each) on 4 ohm

Need Help in:

Connecting all 6 speakers to the amplifier in such a way that the amp does not sustain damage & maximum efficiency is achieved

P.S: Dont want to add another amp as there is already one for the sub.

Thanks....Kindly tell me a diagram if possible on how to wire them all.

For stereo - 2 speakers in series and the 3rd in parallel. That would be 2.67 ohms.

However sound output will not be balance.

For mono make 2 strings of 3 speakers connected in series.
Connect both strings in parallel across the bridge outputs.
That would be 6 ohms equivalent.

Parallel 3 pairs and series them. 6 ohm mono load. All 6 speakers will move the same. Above layout will have 2 moving more than the other 4. I do know about the damping factor going through the floor, but in your situation this will give you the best result.

If there are 3 speakers per side, connecting 2 sets of 3 speakers in series is more convenient and uses less wire.
Impedance will also be 6 ohms in bridged (mono) mode.

As mentioned, there is no suitable stereo combination.

I did not see the second half of your first post.
