This is a fine hypertrophy program, but it is far from optimal for strength. If you're seeking gains in strength, then you need to change quite a bit of this routine.
First of all, as mentioned, you aren't going heavy enough. If you have been lifting for awhile and have adequate form, then work up to a 3 or 5RM for your ME exercises.
Secondly, your exercise selection needs some tinkering. Throw out the hamstring curl and leg press. Substitute a good morning variation for these exercises. Also, I probably wouldn't do Arnold presses as your first assistance exercise.
On speed days, your volume is a bit high. For squat, try 8-12 sets of 2, and on bench, 6-8 sets of 2-3. If you deadlift on lower body ME day, just do singles.
Getting back to not going heavy enough, if you haven't been training with heavy loads, then the type of set/rep parameters you have are OK. Ideally, though, you'd want to have a setup something like this:
ME exercise: work up to 3-5RM
Assistance: 3-4 sets of 3-6
Assistance: 3-4 sets of 6-8
Supplemental: 3-4 sets of 12-20
So, for a lower body day, that might look like:
Hope this helps. I'd be happy to try to answer any questions about your template.
