Alternate source of power?
|
New member Username: SamdemlerPost Number: 7 Registered: Oct-08 | Was just wondering if there is a way to have an alternate source of power, power your subs.. Like say you have your battery hooked up to an amp which already powers your 4 indoor speakers and don't want your amp that powers your subs to be hooked up to your car battery.. any options? |

You could have multiple batteries but they would ultimately be charged off the same source. If you're worried about excessive draw then start with a larger main battery, followed by the big three and bigger alt. If you can find a way to power your subs without involving a battery then you my friend are too smart for this forum lol. |

It's kinda like a bank account. Your job is like your alternator, replacing what you take. Your spending habits (car audio) along with your cars' normal draws are your bills. Spend more than you make and eventually trouble results. It's all economics.  |

The main purpose of a car battery is to start the car's engine, and to smooth the voltage output of the voltage regulator. you can run a car engine just fine without the battery. It's done at dragstrips fairly often. That said, you can run multiple alternators, although it is a lot of work and expense to do so. The alternative is one large alternator 200A+, depending on the stock alternator output, and as noted, use a battery isolator and a bank of deep cycle batteries dedicated to the audio system. The batteries and alternator will work together to supply the current that way, and even if you do kill the bank of deep cycles, the car will still start just fine via the battery under the hood used as a starter battery, because it never "sees" the audio system thanks to the isolator. |

New member Username: Jumbo23Post Number: 3 Registered: Sep-08 | So..I'm just trying to get a straight answer from someone who knows what the hell there talking about. I own a Yukon Denali with 2 subs and a JL 1000/1 amp. My problem --- dimming lights when I turn it up. I've heard everything from get a capacitor, to replace my current battery(high cranking), to get a second battery(yellow top), to get a higher amp alternator. So which is it??? Can anyone tell me what would be my best option?? |

The capacitor will only help to filter AC ripple. the battery helps when the car is turned off. the alternator supplies the current when the engine is running. see www.bcae1.com for details on how the charging system works if you wish to educate yourself on the topic instead of asking others to tell ya what to do. your call. |

New member Username: Jumbo23Post Number: 4 Registered: Sep-08 | Got any recommendations on types of both? Wouldn't upgrading the stock alt. from 105 amp to a 145 amp make a difference? What price range am I looking at? Thanks for the advice!! |

New member Username: Jumbo23Post Number: 5 Registered: Sep-08 | Thinking about getting another amp. Can anyone tell me about Hifonics amps. Thinking of replacing my current JL 1000.1 amp with a Hifonics Bx2008D amp. The Hifonics amp get 650-2000 watt/rms range. Which do you think is better? Any advice would grateful!! |

Platinum Member Username: GlasswolfNorthWest, MI USA Post Number: 12431 Registered: Dec-03 | if the stock alternator is 105A, your car alone probably uses about 60-70A of current max, plus figure about 100+A peak draw for that JL amp, so you want something in the 165-200A range to be on the safe side for alternator output |
