I'll be powering a 12" xcon off a saz 1500d and mli65/not sure about tweeters on a sax 100.4d in a 96 volvo 850 glt. The stock alternator is a Bosch 90amp, and I'll be replacing the stock battery with a Kinetik 1400 (already purchased). I'll probably be putting a kinetik 2400 in the back as well. But will this be enough? I have 235k miles on the car, so not sure if I want to get a heavy duty alt.

Also, which charger should I be using: 45, 60, or 80 amp?

Posting here since it's 10pm and likely won't get an answer from kinetik soon (holidays), but I did email them anyway.

After reading around quite a bit, I'm thinking the 90amp alternator just will not cut it. I suppose I'll send out a few emails to ohio gen/dc/mechman for a quote instead of picking up the kinetik 2400 just yet. I am still curious about the charger question. I'm sure the 45 amp will be fine for the khc1400, but can I use it to charge both?

Only reason you need a charger is to charge your batts while the vehicle is off. And AGM style batts like slow charging, 2-6 amps.

Why do you want such a large charger anyway?

I've searched the hell out of kinetik 2400 charger or kinetik chargers and found virtually nothing. The kinetik site says to use at least a 2-stage charger, but only have their 45/60/80 amp chargers listed. I found a kinetik 35 amp on ebay for $99, but wanted to confirm it would be powerful enough. My original thought was to keep the 90amp alt, and just charge/top off the batts every week or two.

Edit: AGM charger came up with better results

I just bought that same Kinetik charger for my hc600 and 2400

It doesn't work like that unfortunately.

The charge or "top off" would only help for a few seconds then it will be like it never happened. You really have no use for a charger as you will only have two batteries. I have seen chargers help when there is a large bank of batteries and you charge them to burp.

New alt it is, thanks a bunch man!

That is the best thing you can do man. Hit up DC Power alts, I have heard great things about them and great prices as well.

The smart power supplies are a constant voltage powr supply. The 45 amp would work fine but if you mix different sized batteries you should charge them individually. For practical uses I would lean more towards their inteligent charger (35 amp as you put it). A high output alt should be put in however and use the charger to keep the batteries maintained..it is a handy item to have to maintain all of your 12v car batteries.

Aahh, that's exactly what I was looking for.
