Seperate Battery?

[BanginJimmy]

it would be cheaper to simply get a powercell. ho alternator would cost the around the same as a powercell. a better battery might not solve the problem. a powercell would solve any issues you might have...unless you're pushing like 6 12s or someshin like that

Actually you couldnt be more wrong. Unless you are adding more charging capability, you are just adding something else to charge, therefore making your charging system worse, not better.

A lot of times, a better battery will help on a smaller system. Most have larger reserve capacity and are more efficient.

ALL times a big 3 upgrade will help more than anything short of a HO alternator and should be a requirement for anyone with a system, no matter how big or small. It should also be the first step in improving your electrical system.

The next step is a HO alternator. A stock alternator, especially on an small car, is too small and provide maybe 100 amps max, more likely around 75 at speed and closer to 60 at idle. You simply need to add more charging capability which means more amperage, which means a HO alt, not just a rewound.

NOTE: Big 3 MUST be completed first

Next is a second battery. More capacity is just that, some large systems need that.

The final step, dedicated charging system for the audio system. This includes a second alternator that charges anywhere from 14v to 24v and is completely separate from the vehicle charging system. Also included is at least 1 dedicated battery, usually multiple batteries in these applications.
