200 amp alt?

[Anonymous 10+ year member]

Where can i find at least a 200 amp alt for a 2004 Dodge Durango. And if i can not find one what would be my other options. I have 2 Viper 1200's and a Viper 200.4. I have an 1100 Amp Rockford Battery and a 1 farad cap. My voltage drops to about 10-10.5 at idle playing it at normal volume. I would like to keep it around 12.5-13. So doing the big 3 help? If so how much? And if that does not do it what else can i try? Was going to use the biggest wire for the big three and i am going to upgrade the fuse under the hood to 200-250(right now it is 150) Do you think doing the big 3 and upgrading the fuse would give me the voltage i want? If not what will because i do not want to fry my shit

What i mean by normal volume is the loudest i turn it up

I don't feel like reading all that, but you can get a good high output alternator from http://www.excessiveamperage.com

^Yes, definetly. The BEST price out there for the BEST alts out there!

And you dont want to pound at idle. Even with a high amperage alt, at idle your alt can only produce about half of its rated current (unless its constructed to do so). If you have it at a higher RPM, all is available. Try running at 2000 RPM in your durange and see if it helps your voltage drops. If it doesnt, then get a new altenator.

BTW: Excessive amperage has an amp model that turns on and can provide all of its rated current at low RPM's. (Like at idle speed) They are only a bit more expensive too. Just email him for a price quote, and he should give you both options.

Sounds like your alt is dieing, blasting your system in idle with that much wattage will fry your alt
