Big Three XS power up front and in back. What size alt?

Nothing. In the long run, it's going to easily kill your alt. If you have the money to drop into a legit 3000rms amp, just save a little more/wait and grab a 225-300 HO alt.

i have the stock, i believe its somewhere around 130

And it will die quickly with a 3000wRMS amp.... 130A=1300w...

i was planning on getting 2 120ah batteries and a small kinetik upfront....would that do me any good?

It will cover up the problem. I've heard of people running 2500-3000 on stock, but that is to each their own. I personally wouldn't even take the chance, as you could fry the amp. Why not just save up for a little bit longer, do it right, and get a HO alternator?

are those high output alternators on ebay any good?

 

[MikeyF 10+ year member]

Not sure. I know Mechman and DC power are highly recommended. You talking about the DB electrical alts?

 

[norrizzle90 10+ year member]

yeah the db electricals

Best way to do it is with a bigger alternator and correct batteries. Even with a 225 amp alt you run the potential into drawing more than the alt can put out over all and at idle which will tax the batteries and eventually the alt. I would add a voltmeter display and check the resting voltage of the batteries. If they were starting to go down from an original voltage of 12.9 and start resting at 12.6 you need a charger. In that case I would pony up and just install one of these Kinetik High Current Power Cells and plug it in when needed.Its cheaper than destroying batteries and you can always take it with you into another install or leave it in as you upgrade.

He has a voltmeter already installed. I have been telling him to get a H.O alt but he thinks im just telling him to spend to much on his system lol.
