We study the low-temperature dc transport through a nonequilibrium double quantum dot. We show how the Kondo peaks in the spectral density evolve with the interdot tunneling amplitude TM. The nonlinear dc conductance displays one Kondo peak at zero dc voltage. The height and the width of this peak as well as the ratio width/height strongly depend on TM.
