Concert sound 2 system with EQ head unit. Will I be safe with these speakers?

[GNVAIR]

I have the Concert Sound plug that I modified to run the front speakers in series rather than parallel.
I have a set of Pioneer 4x10s that are 4 ohms.
I have another 2 sets for the front (3.5's for the dash and 5.25") for the doors. Both sets are 4 ohms.
Would this be safe for the stock head unit?

Yeah you're fine running the fronts as 8ohms off the front channels. Where you run into problems is when you run 4ohm speakers in parallel and drop to 2ohms.

Yes, since it's in series, the front channels will be 8ohms
