And if you're pushing another 1800W, at 100% efficiency, a crude power formula is P=IE, where P(power) can be derived by multiplying I(current) by E(voltage) and if the alternator is charging at maximum voltage of 14.4VDC, 1800W will draw 125A. If you want to use this many amplifiers, you'll also need a higher output alternator and a heavier charging lead.

If you really want to make this system sound good, I would advise against using cheap amplifiers.
