It allows that, but the built in factory AMP will not allow that since the speakers are wired in series if I'm not mistaken. Basically the left hand speakers are wired as one, and then the right side wired as one again. It does have a built in EQ with great control of the highs, mids, and lows though. Which for me was enough, as I put in new Infinity Reference 6032 speakers in the doors anyway as an upgrade from the stock ones. Lemme tell ya, big difference in sound output, and also range of sound.
