So i just bought my sisters cavalier for a daily driver. I don't drive my mustang in the winter. Im wanting to put a decent system in it. I have 2 12 inch infinity reference's in the mustang and there pretty loud at 750rms give or take. But Im thinking of doubling that for the cavalier. Im looking at putting in two alpine type r 12's in it. probably run between 1200-1600rms to them total. What do you think i need to do for the car to be able to handle that kind of load. Upgrade battery, add a battery, upgrade alternator?
addition info: car is a 99 cavalier, 2.2l engine. i think the stock alternator is like 60-70 amps.
