Hi,
The Amp is rated per channel, so adding the speakers to dedicated channels will not draw down the power of the others.
I suspect what you're experiencing is the balancing effect the rear speakers have. Before, you were totally Front Staged and your hearing and Brain adjusted to that. Now, the Rear Channels are reducing the Total Front Staging - your ears think the Fronts have gotten quieter, but they really haven't. You turn the Volume up to 22 to return the sound to match what you're used to. It's like an Optical Illusion for your Ears...
To be on the safe side, as mentioned, check all your connections to be certain you're not hooked up out of phase...
Happy Motoring!... Jim'99
