    Hello. Are there any limits on the amplifier amperage draw on the 12v system? Would a 400w 4channel and a 600w sub amp be ok to install without compromising the reliability of the Prius 12v or hybrid systems?

    That will work fine. The peak demands by that gear will be close to the car's limits, but that's fine because it's only the peaks. The long term average draw will be much lower, well within what the Prius can supply. Just make sure you tap in on the load side of the shunt so that the car is properly aware of this extra load.

    I might suggest that you replace your 12v battery somewhat more often because it is on the small side. So instead of letting it go 4-5 years maybe replace it every 3rd year or so. Even that may be overkill.
