Capacitors worth the $$$?

Um, no. Obviously the dimming is cause by the voltage drop. The electrical system cannot keep up while the vehicle is running. Adding the extra battery(another load) will further compound this issue. The alt is already having problems supplying the proper voltage and current to the vehicle and it's accessories and adding another load will further degrade it. The extra battery will do nothing other than provide a possibility for a small increase in voltage after the alt gets past it's limit, but that's futile at best as it will not be getting charged by the alternator if it already cannot supply a high enough voltage to prevent dimming.
Do you think that Steve is actually using the system to it's full output potential while driving around bumping? Highly doubt it. Even if that were the case, he would spending quite a bit of time recahrging the batteries after driving. The music material will only pull a small amount of current from the amplifiers. They are not going to be operating at full tilt with max current draw the entire time.

The ONLY requirements for the battery is to provide the current and voltage to start the vehicle or to run accessories with the vehicle off. Once running, the battery is to be nothing more than another load (being charged by the alt). If you require an extra battery to make up for the loss of voltage due to a poor electrical system, it's only making it worse.

Very well said.

Lmao, YOU JUST MADE MY POINT DUDE!!!..

Since I'm a newb (not hardly) why does steve have all those batteries??? You mean 2 300 amp alternators is not enough?? Why, cause 2 300 amp alternators could NEVER keep up with 8 bd 1500d!!!

The batteries provide support for the alternator so when his system NEEDS more than 600 amps the batteries are there to fill in the gap... ( i would think with those amps and all the accessories that would be easy to do)

With the system that is described by the origional poster, (a system very similar to my own) his stock alternator will not have ANY problem keeping both batteries charged. He never mentioned getting a h/0 alt, he was debating getting a cap. A small 2nd battery would be the least expensive way to go, it would be better than a cap, and would not harm his alternator AT ALL

how many people do you know who run 5k watts(and more) for daily with just a h/o alternator ONLY????

To the origional poster, just upgrade your wiring like was mentioned before, and get a small 2nd battery.. It's cheaper than a h/o alt, and better (and cheaper) than a cap. just my 2 cents from the resident newb

I just re read that... are you SERIOUS????//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif In the realm of normal car operation this is true, but were talking car audio. The current draw (depending on how large your setup is) can easily exceed the output of an alternator...

btw what type of setup are you running.... with all this great information your providing I'm very curious...

I made your point? Tell me the logic in your point, which is this. Once the alternator gets to the point where it needs voltage from the batteries, it is not working anymore, therefore your batteries are not being charged by the alternator either. SO then what happens? The batteries are being drained.. Does that make it worth adding another battery when the charging system already cannot do it's job???

When your alternator goes out or you lose a belt, you don't notice at first as the battery is providing power for spark and vehicle accessories. Once that gets to the point of exhaustion, the car dies as the battery alone can no longer support it. It is dead. Same situation when the alternator can no longer support the load of the vehicle and accessories.

And never once did I call you a noob. I don't point fingers, call names or any of that BS. We're simply having a discussion, so leave it at that.

Current draw may easily exceed the output of the alternator, but they RARELY draw near their full output during musical playback, Hence I asked if Steve would be driving around at full tilt all the time where current demand will be at it's highest.

My system information is irrelevant to the topic.

Your funny, what happens when the current exceeds the output of the alternator????? Where does that extra amperage come from???

I agree the alt is the source of power. This is clear. However when the current draw exceeds the powersource, the BATTERY will supply the remainder of what is needed. That is the ONLY thing Im saying...

My suggestion for the battery over the cap is once the cap is drained thats it, while a 2nd battery will not drain completely on musical transitions...

**edit**

After re-reading the post(s) your correct and I do apologize for making references that you called me a newb.

Are you even reading my posts? My ORIGINAL POST stated that when alt cannot supply the demand, the battery will take over. And like I've said several times again, once that happens, the alt is no longer charging the battery. Not good for either part.

I'm done here.

 

[fozzymuphet 10+ year member]

so basicly here's the steps

1) Big 3

2) (if big 3 doesnt cut it) Big 4

3) Number 2 was a joke it

real 2) geta h/o alt

3) another battery

4) Preferrably do number 2 and 3 at the same time

BTW i am a newb but i was trying to summarize what these two were argueing over
