Power Question (Battery/Cap) |
|
|
I am going to be doing my first nice install in any of my cars in my new (to
me) 99' 528i. I have a Directed 1100d (old style Black and Silver). I am
going to be going with 4 of the Kicker S8L5's in a sealed box. I love the
sound of the current S10L5 I have but want a bit more sometimes. Now I think
I have it measured correctly for Amp/Sub ratio. That Amp should put out
exactly the right amount for those 4 subs in a 1ohmish load.
My question is:
I REALLY don't want to jack up the battery or any of the power devices or OE
cabling in the car, I haven't really cared in the past with my Junker cars
but this one I want to take car of. My question is, with that type of setup.
Should I buy a Optima Yellow top and install that into the car also? Or
would a standard 1 Farad Cap or 2 do the job well enough to cover
everything.
If you need anymore info on the subject please reply and ill try to include
that.

Thank you,

ok.. you need the lanzar 2.4 cap like i got. $99.
theyre going to tell you not to get a cap...theres pros n cons to
it..its your call.not thiers.
the reason for a cap is to supply you bursts of power faster than a
battery can.
now i paid $80 for my cap 8months ago.they went up.
also caps recharge every minute or less,i think alot of people think
they recharge after theyre totally dead.causing you battery problems. |

Branden,
With that kind of power you would be fine with a good yellow top and
disregard any notions to caps. Also, completely ignore Bob Wald's advice on
anything car-audio related. I'm sorry to involve you in all this, but we as
a newsgroup are in the process of banning together to ignore him in the
hopes he will go away.
Also, any reason why you want four 8s as opposed to a couple of 10s?

If your alternator won't provide enough current to supply your car's
electrical system and your stereo needs, with a little left over to
keep the battery topped off, then no battery or capacitor will help
you.
That being said, I would replace your battery on general principle if
it's the original battery, and an Optima or Stinger is as good a
choice as any.
A 1999 BMW will probably have a pretty stout alternator as standard
equipment, so I'd install the stereo and see if you have any problems
with you battery discharging, lights flickering/dimming, etcetera, and
then go from there.
Unless you're cranking the stereo at full blast all the time, the
*average* current requirements for your stereo will be surprisingly
low, even for a "big" stereo.

Re: Power Question (Battery/Cap) |

The reasoning I am wanting the Four 8's instead of Two 10's is that with the
L5 series by kicker (Square subs) the 8" equals the surface area of a
standard 10" round sub. In this setup I would be running the equivalent
surface area of Four 10"s in a sealed box. Also with 8" L5 they only require
a .33ft^3 box per sub. In my 528i ill have those 4 in a total 2ft^3 box with
each having their own .5ft^3 box inside the box as a "whole". This will Fit
nicely in the front part of the trunk and still leave me access to a useable
spare tire while having a nice professional looking install. :)

As far as the Cap being $99 and the Yellowtop being $159+, I dont have to
worry about that i can get a Yellowtop for abour $120. so that price doesnt
matter.

Re: Power Question (Battery/Cap) |

Unfortunately I am not sure what the power output of my Alt is on that car.
As far as replacing the battery with a Optima or Stinger, Unfortunately
where BMW place's the battery in their cars (Trunk) it requires a battery
that resembles a 'stout' Marine battery, so a normal Yellowtop type battery
wont fit in the stock area. There is however a nice place to install a
second battery above the stock one if I go that route.
Main reason I want a second Battery or a cap is that I don't want to over
tax the Alt or standard battery as I have heard either one is pretty costly
to replace.

Adding a second battery will over tax the Alt since it will work twice as

Re: Power Question (Battery/Cap) |

That is a good point... Hmm..
Looking at the 'Standard' Stock Equipment on that car it has:
-120 amp alternator
-90 amp battery
As far as I know the Amp has not been changed. I do however think the
battery has, as it has a Interstate battery in there right now I believe. So
maybe just running with it all and seeing if something *might* break, would
be a better idea the over doing it and actually hurting it more overall.
Would a Cap effect it as much as a battery if I used that?

A cap will not effect the Alt. It can help the bass response.
Whenever the bass hits the battery voltage drops a little.
The Cap discharges at that time to keep the battery voltage steady. |

Ah, so im prolly beating a dead horse on adding anything, to help with over
all load on the system. Also looking at that FAQ (still reading though) it
would be better to upgrade the Alt in this case then to add a cap/battery to
the system.
