  We study the asymptotic behavior of the twisted Alexander polynomial for the
sequence of SL(n ,C)-representations induced from an irreducible metabelian
SL(2, C)-representation of a knot group. We give the limits of the leading
coefficients in the asymptotics of the twisted Alexander polynomial and related
Reidemeister torsion. The concrete computations for all genus one two-bridge
knots are also presented.
