Currently Im runnin 2 RE SE 15s with about 2400 watts rms ..Got everything wired to 1ohm.. I was lookin to upgrade batterys (After I do the Big 3 upgrade) . Also Im on the stock alternator.. I dont have huge light dimming issues but notice that when the bass hits hard, my voltage drops to about 9 to 11 volts!

Would a kinetic HC800 be enough for my system? Or Should I go Bigger? Im not looking to run more than 1 batt but simply upgrade the one i hav.

 

There is no way you are dropping that low without your lights dimming. If you want that much power you will most likely need to buy a ho alternator. Adding batteries without having the right alternator to charge them isn't going to help.

 

 

Have you tried an Optima

 

9volts is pretty damn low. I'm surprised your car is still on at that point. I would recommend getting an HO alt. Getting a better battery isn't going to fix the issue.

 

This. And I would imagine they're doing damage to the electrical system.

 

i get a lil bit of dimming inside the car but no dimming of the headlights..The only time it drops to 9v is when there is a constant low low bass note..otherwise it'll drop to about 11. the cars got 120k miles on the stock alt..So i guess now would be a good time to upgrade! thanx for the feedback

 

calculator what amp do you have?, how many fuses are in it? you need to calculate your amperage draw a bigger alty is a good idea but it will have to custom wound they don't make an aftermarket ho for Maxima's

 

Thanx for the calculator..
Ive got an alphasonik PMA 1200DA..Im not sure about how many fuses it holds

 

just look at the fuses on the amp and see how many you have

 

There is a company that makes an ho alty for the max. I remember a member here buying one. I will search and post link later as I am on my phone

Here is that thread

 

I had a 200 amp alternator on my 6.5 gen from excessive amperage. Talk to Nate, he's a good guy.
