I have a 2009 Nissan Maxima with a bose system, but no navigation. I want to upgrade the stock Bose System. I haven't installed anything yet. I have a 12 inch JL audio w6v2 powered by a 600 watt mono Kicker amp. I have 2 pairs of components for the front and rear doors (Boston Acoustics Pro Series) powered by a 350 watt 4 channel Kicker amp. I do not want to replace the Bose headunit because I heard that I will lose a lot of features. What I want to know is how would I install a JL Audio Clean Sweep? Could I hook up both amps to the cleansweep? How would I hook up both amps because the cleansweep only has 4 channels?
