Choosing a battery.

[zlibby77 10+ year member]

Here's the situation: I've recently purchased 2 Orion HCCA 10" 4 ohm DVC subs rated at 1500w rms/each. I've also just purchased a Soundstream XXX-4000d amp. I'm looking to upgrade my car battery to possibly an Optima D35 (8040-218) for about $180.

Note: big 3 upgrade is done. I've also got two other PPI PC250 amps running my mids and highs.

Is this Optima battery sufficient? Or... what's another good choice? I don't really want to spend more than $250 on a battery, but if I must, I can go a bit higher.

I look forward to hearing from you guys.

There is a great deal on the Deka G31s on this site for $150 shipped IIRC, jump on it. They are GREAT batteries for the price.

ive been running 2 red top d35's for a few years now and have not had any problems with them.

Do you have a h.o. alt?

 

[zlibby77 10+ year member]

Misfit,

I don't have a H.O alternator.

I've got a 2003 Nissan 350z with a 110 amp stock alt.

How much of a difference would an upgraded 190 amp alternator be for my setup?

Would a 16v battery make sense to use? I'm not sure the pro's and con's yet , and so I'm still a student to this game, so I'm always looking for info.

I'm no expert, but I'd be expecting some massive voltage drop if I were you.

The Soundstream XXX4000D is rated for 3,300 watts @ 14.4v. I don't think you'll see 14.4v on a 110 amp alt and an single Optima Yellow Top...and that's not even taking your 2 PPI PC250's into account.

You're going to need a high output alternator and at least 1 serious battery. Give http://www.mechman.com a look, and check out the Kinetik HC3800 too...

Yeah, I've been eye f@ckin that Kinetik HC3800 and have been 'shoppin' for one. Now, I went to the mechman site and they didn't have an alt for my '03 Nissan 350z. In your own opinion, what would be a good size alt for the kind of power I'm looking to push?

I've looked at some 190 amp alt's, but I'm not sure if that's too small or just right. What's your thoughts on the size of alt that would be a great fit?

Call this number. 1.888.632.4626. Tell them how much power you'll be running and ask for their recommendation...

this. if these truely are the intimadators this is a good deal. theyre some great batteries. i thiink mobieus had them for sale?

Without a highoutput alt it might need 1 or 2 batteries in back. Group31 sized like a kinetik hc2400 or Odyssey pc2150 or 2 group 27 batteries kinetik hc2000 or odyssey pc1750.

Watch this. It will give you a good idea on what size batts you need.

Great link. Learned something new today. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

about the only diff in batteries that realy maters to me is that the jell type puts off less fumes for in car use other than that a battery is a battery. unless of course you sell batteries then the one you sell is this best with out a doubt. as for voltage you alt is factory set to 13.8 or 14.4 depending on what car you have. if you were going to run 16.6 volt you would have to have a seperate circut for your amps so as not to burn up your ECU. to see what needs you have just check voltage at the amps it should not drop much below 14 volt with the system cranking at three quarter volume for several minutes. no amount of batteries or brand of batteries is going to produce magic power power comes from the alternator. now if you were wanting to run you music for a long time with the engine off thats a different story in that case you would need extra batteries but then you would have less than 12 volts to the amps at all times. a 12 volt battery has 6 cells each stores about 2.01 volts resting and while being charged a chemical reaction takes place and each cell producesses 2.4 volts (2.4 x 6 = 14.4 )

It's good for basic understanding. It misleads on a couple of points but sort of touches on it. When he was talking about what you would need to create 2000 watts and said if your voltage dropped the amp would draw more current to make that same 2000 watts. That would be true but when the voltage drops the amp is no longer capable of drawing 2000 watts. They sort of say that when they show the 1860 watts or whatever but it's not clear for the noobs. Most noobs think that the amps just draw more current to make the same power when the voltage drops and it's simply not true. They don't put out as much power when the voltage drops. Also, he said that batteries are usually at around 13v. In reality under even the most minute draw, the battery quickly drops to ~12.6v.

Ya, I didn't agree with a few points in that video at first either (see my comments as jake78999). It does generalize alot of complex concepts (such as assuming all 100Ah batts put out the same power), but it is a pretty good place for people to start learning without getting too deep into the details.
