Well I want to make a Subwoofer using mentioned chips, I have already made the main amplifier using TDA7386 which happens to be a superrrrrr chip 4 channel 45 watts each, now for subwoofer I have the choice of above mentioned chips but does anyone have the idea how to operate them with 13.2 Volts of Car bettery, as the data sheet of these chips do give a hint of single supply biasing but required voltages to bring the chips into ACTION are not,
CAN ANY ONE PROVIDE HELP???

I Messed up things
Guess I messed up things please read as LM3875, LM3886, and LM47xx, joining two batteries is a good idea, I knew it already as u all know its kinda difficult to place an extra battery in the car even if u put it how would it be charged, so any other solutions...............
Any one with some other solution?
