Default Splitting 5ch JL amp into more speakers

Hi guys, just want to get great clean sound with the new JL 700w 5ch just purchased. I do a lot of the work myself all the previous times and this time I want to get the best advise possible. This 5ch amp has the 5th channel as the subwoofer channel, so I wont be splitting that one. The other 4 channels have to be split to feed 6 speakers total. I want to know the best and safe way to sound great and avoid speaker damage. I know all my speakers are 4ohm rated I believe but I still dont even understand what that means to me. Again, just want the best way youd do this without adding an amp. Here what my equipment consists of:
Amp- JL 700watt 5ch
(2) M770 speakers
(2) MX770 speakers
(2) MX650 speakers
No head unit, ran directly to the amp from Bluetooth device.

Any help is much appreciated!!!

Pretty simple put the four closest to you on one channel and the other two that are farthest on the two left over.

Unfortunately the only way to wire 6 4ohm speakers to those four channels of that amplifier would be to bridge the amp to two sets of three parallel which would be a 1.3ohm load. That amp won't handle that impedance. You are only going to be able to power 4 speakers with those four channels of that particular amplifier. I have a pair of M770's in my tower running off a bridged MX280/4 and it keeps up nicely with the four M880's powered by two MHD600's. So adding a MX280 might work.

That amp is 2ohm stable. You can double up easily. You cant use sub channel as its low pass only.

Obviously its the wrong amp for that set up but he has what he has.
Is the amp new or used? You should be able to sell and get what you need. We probably have a demo m600 we could work something out on.

I would put the m7.7s on there own channel and the mx series together. Reason: M series can handle more power the MXs are not to picky on power. I have my MXs on a shared channel as well. Best of luck.

Exactly my thoughts.
