Hey CL,

Some of you know that my amps have been shutting off due to low voltage and that I've killled the battery a few times testing the system. Caps haven't really made a difference in how hard the Bass hits, for extended periods, or the voltage in the system so I just bought an Optima Yellow Top D34.

My question is, can I take the stock battery and put it in the trunk to work like a cap? If this wouldn't work, please explain why. I know it will discharge slower than a cap but what else. I am also considering the BatCap 300 to replace my Lightning Audio Caps. Will I need it after upgrading to the Yellow Top?

My other question is to validate what an installer told me:

"My amps are drawing more current than they need because they were both A/B Class versus D Class amps." And this is why I'm having voltage problems. I'm pretty sure it's because I'm drawing 1200 watts + and Alpine Head Unit, HIDs and Fogs from the factory battery.

Any and all comments are appreciated.

 

Nevermind, found the answer from BatCap.

"A conventional battery, as we all know has a positive and negative terminal. The chemical reaction within creates a flow of electrons, causing an electronic device (in this case an amplifier) to work. The stiffening capacitor is similar to a battery in that it stores a charge. The fundamental difference is it cannot create electrons. It can only store and supply (discharge) them upon demand. The advantage with a capacitor is that it discharges in one twenty thousandth of a second, unlike a battery that does in one second. The battery therefore cannot discharge fast enough to effectively supply the amplifier and this is the reason for "power sags."

 

Unless you get bigger alternator no ammount of batteries would help. You are starving your power system.
