3000 Watts will this be enough

Hello All,

I drive a 2004 Mach 1 Mustang V8 32 valve DOHC engine.  I am buying a alternator to upgrade the one with the car from 120 to 220 Amps.  I am going to put in 2 yellow top batters in the trunk and wire them ++ and --. I also have a 10 fared cap.   Will this be enough to power all 3000 watts?  The alternator will be strong enough to charge the battries, I know this for sure the only thing I don't like is during contest I will have to shut of the car as there will not be enough from the alternator to power everthing. 

Thanks For any help,

Randall Williams

what is the amp ?

All are JL Audio Amps 2 - 1000 each sub amp's and 2 - 450 4 channel amps.  I know the can do 1000 watts from 11.5 - 14.5 volts....as well as the 450's.

Thanks,

Randall

if you are looking to post high numbers on the meter with the car not running i would go with 2 or 3 kinetik battery's the the HC 2400 or the HC 1800 thereis a calculater on the site but i think its for if you car is running heres the link www.kinetikaudio.com there not cheep but there worth the money

I already have one about 3 months old just need to go down and buy the other...  Will this be enough for 3000 watts?

320A alt. would be hard to find, not to mention expensive!!

I dont' know why people think optima batteries are sooooo good. They really arn't unless you need a sealed battery (off road applications). Just buy a marine battery. A big one...lol

Well I have to buy on base as England hits you to hard on taxes.  And the only ones they carry are optima yellow tops.  So I bought the second one today if they run out you might not get one.  Now the yellow tops downtown cost about 400.00 I can get them on base for 150.00 each.

Thanks,

Well Lets see. from JLs PDF file for the 1000/1 they recommend you use a 100 amp fuse
For the 450/4 they recommend a 60 amp one so lets add up your total

100 + 100 + 60+ 60+ = 320 amps at full volume all the time with a sine wave

Real world would listening would be 1/3rd the amperage or 106 amps

So a 220 amp alternator will work in the real world, though im a fan of bigger is better if you can afford it

Have a good one

Thanks for the input that is what I was looking for.  As far as battery I had to choose yellow top as I am in England and it was the best and only one I could get.  If I go downtown same battery cost 400.00 where as on base get it for 150.00.  Now I guess I might be fine charging 2 yellow top battries with a 220 amp Alt and the power requirments of the engine running as well??

You should be fine with what you have, the 2 yellow tops will help when you are playing your system with the car off and a 220 amp alternator will charge it nicely while your cruising the M8 at 194kph

Enjoy

Sir,

1 more quick question for you.  With this setup how big of a fuse should I install within 18 inches of the battery?  As I don't want a meltdown of the car system.  If the Alternator  is 220 amps would I want a 250 Amp fuse or a 200 amp fuse? or less?

Thanks,

Randall Williams
