Exceptional value

The 4SC works great. I installed it in my 07 Mazdaspeed 6 using the line level inputs, and hooded it up to the factory Bose speakers (2 ohm). It made a huge difference over factory, well worth the $80 it cost me. Setting up the phantom center channel was easy too, and works pretty well. Would be nice to see a high pass filter on it, but for the price I can't really complain.
