Sir magtatanong lang po, i'm planning to setup my car audio with 2 power amps, isa pong 4 channel for front and rear speakers and 2 channel bridgeable 760W x 1 (4Ohm brigded) for subwoofer (10" DVC * 2 Ohm 350W RMS or 1200W Max)

Sir ang tanong ko po ay yung magiging power supply ng dalawang amps? direct po ba ito from the battery or may iba pang power supply na kakailanganin? hindi po ba magkaroon ng concern sa power requirement ng dalawang amplifier, knowing that it will eat lots of power when it's ON. di ba magdidiskarga ang baterya sir? TIA po..for any feedback and suggestion.
