Do I need an extra car battery for my system?

Question

I am installing 2 12" subs at 1000 rms each, an amp that puts out 1500rms, a pair of speakers that are rated at 60 rms and another pair of speakers rated at 65 rms.

Help is much appreciated.

Answer 1

You should be okay depending on your alternator output, I had about the same with a 90 amp alternator and I was fine. But I wouldn't get a second battery, I would just get a 1F capacitor and that should keep all the juice you need.

Answer 2

depends on your car.

i've got 2500+rms(without the amp) and i need an extra car battery

Answer 3

Naw, your fine. If you don't have any lights fading, and you have a good healthy battery that should be no problem. I have 2 kickers running at 1200 rms each, 75 rms speakers, a 2000 amp, underglow, inside neon, strobes, flood lights, and my battery is running fine.
