my cousin is startin a comp car and he currently has: 4 earthquake holees15s, 2 rockford T15kW amps, and 2 absolute 60 farad digital capacitors. how big a batterie bank would he need if he was adding 2 more earthquake holees15‘s, another T15kW amp, and another capacitor the same as he has
woofer man is more on the right track though itll only 4 high output alternators and about 8-12 batteries but you will need about 5-8 runs of 0 guage wire. your capacitors were a waste of money
It sounds like he has the cash to do it right, so he needs to invest in a battery for every 2 amps, and one cap for each battery. Probably 4 or 6 ga cables for power, and one amp for each sub. This will make less resistance. So, let's see, 4 15's, 4 amps, 4 caps, 2 extra batteries, and it probably wouldn't hurt to have a couple in line caps for the stretch from the original battery to the aux batt.'s He will wanna see about getting a high output alternator as well. Here's a non mentioned tip, too. When installing the box, with seperate chambers for each sub, of course, putting rubber bushings under the box, and then bolting each box, or one big box to the car's chassis, it will act as an actuator, meaning it will resonate throughout the car, improving the feel of the bass, and also, allowing the cones of the subs to operate more efficiently because the mount of the basket is secure to the box, adn the box is secure to the car, leaving no play at all available for the box to vibrate around. With ample amounts of power, this step alone will generate tighter bass, and quicker performance. Good luck!!
with all that he might want to get a bigger alternator.
