I have components front and rear. Better sound all around. The front set is run off a 4x50 amp and rear is off the deck. I took the 2 rear channels and bridged them to my 8" sub. Components off a deck sound great and they don't distort as bad as coaxial.... as long as the components do not require too much power. I'm going to remove the 4 channel and replace with mono-block dedicated for sub and run all off the deck. I have my deck faded forward a little to balance sound. Strangely the rears are louder on the deck than they were on amp but vocals are not as clear.
