Answer 1

You need to perform the "big 3." First that will do just about the same as a capasitor. Next you are going to want to get another battery and link them together. If you still notice that you have a battery draining pretty badly then you may want to get a larger alternator.

The "big 3" and info on linking two batteries can be found on google. For a larger alternator you may want a macanic to do that for you.

hope this helps.

Easy answer, start the car and run it for about 5-15 minutes. but if you mean the voltage drops like a stone you might want to look into a dual battery setup, an alternator with a higher current output or both.

Answer 3

A capacitor still drains the battery, it just acts as a buffer so that your lights and stuff don't flicker when your subs pound due to the short fast power draw. If you don't want your battery to go down you can turn down the volume. You can also get multiple batterys and plug in a battery charger when you are at home so you always have plenty of juice to go around.

Answer 4

putting in a 2nd battery is a waste of time unless you listen to music for long periods of time while the car if off...

the big 3 is always a good upgrade for ur cars electrical system, your batteries loosing charge because your drawing more than the alternator can recharge,, upgrading your alternator will sort out that problem summin lyk a 120+ will do fine for your setup. recommended u do the big 3 aswel as upgrade alt

a cap will provide better flow of current to ur amps but wont help your battery in any way, you still will c it going down..

Make sher your ground is tight cause if its loose and every time it sparks it drains hella power. If its not that get some power cap But I suggest you get a power-cell battery
