Alternator and Battery

[89AcCOrDmike]

I'm gettin a new amp to run my fosgates in the back, and the amp is a sony 1000 watt, do i have to worry about my battery and it being drained faster than the alternator can charge it? or is it all good?:pimp:

i don't think so, just try to get biggest battery you can find,

if you run an optima battery and beef up your engine to chassis cable and your alternator to battery cable you should be ok. I was running 1300w and I needed a rewound alt putting out 140 amps in order to keep the stock battery. Also if you have a little dimming, you can also use a 1 farad cap. If you upgraded to a bigger amp id go for an alternator upgrade, but for now you should be ok.

Out of all my systems the only problem i have had is with the lights dimming. I do have an optima battery but was fine before and is great to have now but i would think you can get away with only a cap. I have one but its not installed yet cause the car is away for the rest of the winter hopefully.

I had major dimming happening everytime my subs hit with my old system (2 Sony 12" X-Plod, Kenwood 1000W amp). When i upgraded to the memphis system i just installed a 2 farad cap...$160 and i have had NO problem with any of my lights.

If you do run into probs, get a rewound alt

[joshuabrack99]

or you could save a little money and get yourself a couple small marine batteries and put them back with your amp- you can use them just like a cap-may not look as good as a cap but will save you money- look at competitors with huge systems- batteries are used more compaired to caps

u might want to get a cap.

[AccordEpicenter]

id just get the cap before you get into more batteries, because if you do that youll almost certainly need a bigger alt. Also batteries become a resistive load once the car is on and your current output suffers because it has to keep those batteries charged too so its usually not the hot set up for a daily driver, usually just huge comp vehicles, which usually have multiple alts anyways

it is said that any system over 500w, a cap is recommended, for one over 1000w, u really nd to get one...my 2 cents..

[AccordEpicenter]

yeah even with the bigger alt I have I still need one... Im running 1200wrms
