pls help needed, tanx

Hope it aint in a scoob.... The thing would fall apart.

6K in a car............ get real

You have a 6K system and your asking about alternator upgrades????? Not those market stall "Boss 190485763498765 watts per channel jobs for 99£

Having fun.... what the hell is your system\??

6KW @12V = 500A!

or ~417A @14.4V.

That's asuming 100% efficiency in the electrics.

John.

no! just the 2 15" audiobahn atw woofers run 6K i'v also got
a set of 6 avi mid ranges 2 sets of power aquistic tweeters for sound
i'v got one audiobahn screen with ps2 and tv tuner ,.
with a pioneer head unit with 6 disk changer.

oh yeh AND a 5K zapco amp and equalizers with one 4 channal 600w audiobahn amp.
also runing 2 caps for power storage but only lasts a bout 5 mins if fully charged


pls guys someone must know how to get this system runing right.

my mates got the same sort of system in a golf but hes runing a 120AMP ALTERNATOR.

im having problems finding an alternator..

Gully, good luck on this, to be honest I think you'll need a vehicle electics specialist though, as you'll be drawing a hell of a lot of current with that Zapco amp.

There's a place on the Stanningley Bypass that specialises in alternators, particularly re-winds. I'll do a bit more digging and see if there's any chance that they might know how to do it.

Have you got aircon? I wonder if you could actually run two alternators. I really don't know if that's technically possible, but that might be the way to go: couple of batteries for the system running off their own alternator...

I'll let you know if I find anything out, and keep us updated.

Nick
PS - good luck stopping the rattles :D

Your going to need at least 2 Batterys in parallel..

Would recommend Optima Yellow Top

1 Big alternator, custom mounted is the easiest way

or 2 rewound scoob alternators (about 90a std iirc)

Obviously its not continiuous load so you dont have to worry about a 500a alternator but I would aim for 200a - 250a

Also Might be worth using chain drive / toothed belt if your going serious

If you want a big alternator, do a bit of digging and find out what kam jagpal (sp) used on his transit.. (think they were bosch)

Oh and lots of 0 gauge cable..

David

yes i'v got air con and abs if i put in two alt's it will look like a supercharger as i will have to cut a hole in the bonnet
thats the only place i could put it .

i'v got a yellow top get battery, which has given a little help, but finding a big alternator to fit is a bit of a problem

thanks guys for the help if you can give any more help pls do
my e-mail is gullys01@yahoo.co.uk i'm on scoobynet all the time


tanx AGAIN

Do the math, if your amps really put out 6kW then you're looking at about 1000A current draw. Absolutely no way you can run at that level continuously. What fuse(s) are you running ? That should tell you what your system is really pulling from the charge system. You can run multiple alternators, but that's getting into heavy duty stuff and I doubt you need that.

Steve.

This would do you right...

Hope that link works...

the fuse i have is 200a i dont know if can blow that as i cant crank the system to its full potential.
i'll get my car back next sat .
i'v met this guy who thinks he can put on another alternator buy making new brackets.

thanks for the help again
keep me up dated if u get any new info

Have you tried Stinger. They do competition alternators. Have a look at: http://www.stingerelectronics.com/sting_products/alternators.asp

They do alternators up to 270A.

A Stinger is going to cost him a mint...so is a Prestolite.But the Prestolite will out do the Stinger in every aspect,including size unfortunatly...they're MASSIVE.
Yes,hood modifications will be a must with the newer H4's and these alt's.With the right regulator,you can weld 1/4" plate steel with these alt's.;)

I too make my own brackets for my alternators.Nothin too it...I'm a welder.:)That link didn't seem to work...

www.prestolite.com

I have a 135 amp Leece Neville in my old hatchback...:)

I' love to hear this system once sorted...

Sounds like an Audio Images/Bradford install???

SO U KNOW THEM BOYS AT AUDIO IMAGES U MUST TRAVEL A LOT


the system is ready for next week
as i get my car back with new manifold and aquamist installed. gully

Gully

Used to live in Wakefield and yes I do a lot of mileage

Audio images specialise in that sort of gear.. and should be better than some of the Dodgy dealers around leeds!

I went for Genesis stuff.....

i'v got a split chargher system with two batteries and two caps the system dioes run for a bout 10 minutes at peak

still need alternator if any one can helpp..
gully;

Davinci or Tarantula? Stunning amps...

ah, tarantula - serves me right for browsing without images ;)

2000W RMS? Ouch...

Check this:
0208 997 8232 Sahib's auto electrical.
Got this from the boys at phoenix gold.
He'll ask you for the numbers off your exhisting alternator.

chears matye ill give them a calll

tanx gully

Had a look at a nice Soundstream amp the other day, gold plated thing 2,000w rms. Sounded amazing, knocked my pheonix gold to dust. Very silly money though :(
