I tend to agree with Hagabet, your amps may not be the best choice for the 802 speakers. Bridged amps suit high impedance, low sensitive type speakers. A bridging confirguiration doubles the power, but each amp sees a 8 ohm load as 4 ohm. Although the 802s are nominally rated at 8 ohms their specs indicate they do drop to a minimum of 3 ohms at certain freqs. This means at certain freqs each of your amps will be driving a load of 1.5 ohms! This high current demand may stress your amps, particularly when operating at high volumes.
