We determine the co-representation theory of the universal co-sovereign Hopf algebras, which are some natural analogues of the general linear groups in quantum group theory, for generic matrices over an algebraically closed field of characteristic zero. Our results generalize Banica's previous results in the compact case. As an application, we easily get the representation theory of the quantum automorphism group of a matrix algebra endowed with a non-necessarily tracial measure.
