Fender BXR Spectrum Cab Question

[negativefx]

Hi all, I have a Fender BXR Spectrum cab (2x10 + 1x18). It has a 4ohm input with a built in crossover in addition to the independent 4ohm inputs for the 2x10 and 1x18.

My matched 10s are 8ohm in parallel for 4ohm, 200W RMS.
The 18 is 4ohm and 500w continuous.

If I run a 4ohm 1000W head into the crossover input, will I get a 500W/500W split to the two sections meaning 250W to each 10 and 500W to the 18?

Just trying to understand if running a single 1000W 4ohm into the crossover input is going to blow those 10s out or if I'll be OK.

Thanks!

Your ears are the judge if you hit speaker distortion then turn down.
Otherwise either 50 watts or 2000 watts your speakers will tell you when they are hurting.

Real world, almost any pair of 10's wont to much more than 150watts before 10% distortion. So again your ears are the judge.

the amp does not put out 1000 watts all the time, the level of power is controlled by the volume knob
