Here's my question:
Let $k,B,C$ be positive integers such that $B<C$. Can you give an upper bound for the number of $k\times k$ integer matrices having entries bounded in modulus by $B$ having determinant greater than C?
Thanks for helping!

For $C$ fixed and $B$ large this is (to first order) some constant times $B^{k^2},$ with the error term of order $O(B^{k^2-k}),$ for more see the classic paper of W. Duke, Z. Rudnick, and P. Sarnak in Duke Journal (around 20 years ago). However, this might not be the regime you are interested in.
