Do I need more than big 3 done?

[fooch 10+ year member]

K so I will be running a 2000 watt and a 300 watt amp to my 2002 Ford Explorer stock amp and the battery isn't stock but its just a diehard. I won't be listening to music with the engine off if thats why people need more than one battery. But will i need a 2nd battery to run this system efficiently?

I'm no expert by any means - but this is how people explain it to me.

#1: if you plan on upgrading in the future, might as well invest in one.

#2: If not, Install it how you want with the big 3, and if you're seeing voltage drops, work from there.

How many amps does the stock alt put out?

I'm assuming 130 if its a 3g+ alt.

I'd go for a new alternator. There's no point in having multiple batteries if you can't keep them charged.

but i dont want to have more than one battery if i dont need it.

I wanted to know if i could run THIS system with just the big 3 done nothing else. I guess i got my answer from runteldat I will do big 3 without an extra bat and see whats up. Does anyone know how i can check to see if my voltage drops?

You can run it. As for how well it will work, there's only one way to figure out.

if its effiecient, thne i dont see a problem running it.

big 3, id at least do, with maybe a good under the hood batt, maybe a small one in the rear(a big one isnt truely needed)

with 1/0 throughout.
