You won't need a crossover. However, you will need to have gain control on at least one of the amps. Even though stated wattage is similar, they won't be identical with gain in output vs volume gain. If it were me, I would set the volume to about where I do my normal listening and then set the gain to balance lows/highs. If you are lucky, this setting will remain constant for the whole listening spectrum.
