Why?
your 180+ pounds and want to eat 1500? your going to set yourself up for disaster dude, no offesne. that is a HORRIBLE Idea.
Training heavy is smart, i would also suggest not abiding by ratios. while they may be great to hit to a T the key premise while cutting would be 1-1.5g lb/protein, at least 20% fats and the rest carbs, if you are carb sensitive or think you are and cannot handle carbs very well then higher your fat a touch. ALWAYS keep calories as high as possible when starting to cut and allowing as much room for change as possible and preventing your metabolism from slowing or crashing faster from a huge drop in kcals. Bigger deficits are not always better:

Small Caloric deficit (keep kcals and carbs as high as possible throughout your diet)
ALWAYS train heavy, and lower volume as diet goes on and cardio increases (due to less calories to recover)
Monitor your energy/hunger levels as you continue to diet this will help you
Make sure you implement refeeds or cheat meals to help spike t3, leptin, or hormone levels when they drop from prolonged dieting.
what can happen if you shortchange your calories, and end up leading to more stalls and a slow in metabolism is as follows as stated by Layne norton and metabolic crashing.
