We examine the exclusive rare decays of B -> K-0(*)(1430)rho(rho) over bar with K-0(*) (1430) being the p-wave scalar meson and rho = v,e,mu,tau in the standard model. The form factors for the B -> K-0(*) transition matrix elements are evaluated in the light-front quark model. For the decays of B -> K-0(*)rho(rho) over bar the branching ratios are found to be (11.6, 1.63, 1.62, 0.029) X 10(-7) with rho = (v, e, mu, tau) and the integrated longitudinal lepton polarization asymmetries (-0.97, -0.95, 0.03) with rho = (e, mu, tau), respectively.
