what are some alternators that will fit onto the maxima without requiring a lotta modifications?? I gotta have a bigger one because it can't support all my stuff

 

there aren't.
find a stereo shop that does high end work and ask them for recomendations.
also some rebuilders will rewind the alternator for higher output.
A getto rig is to run a smaller pulley

 

A cap and/or a second battery will probably help. Also your alternator maybe getting bad from taking a beating like mine. Good wiring to the alternator, battery, and amps (or whatever) may also help. Making sure your battery is fully charged helps a little too.

When I first put my system in, the alternator could keep up pretty well but, now it can't even with a 15 fared cap. I just got the cap recently to help but the alternator was so far gone that it didn't do a whole lot. At idle I have to keep my music down quite a bit. I just bought a new alternator and it should be alot better for a while.

 

Btw what is drawing that much current? How many watts(rms)?

 

check the audio forum, i think someone was using a higher amperage unit from another nissan vehicle...

damn, I can't remembered the link I posted here but it was about a year ago when I found a guy selling ~115-120amp brand new alternator for our car (not reman or rebuilt). but you could google for it, it's around $250.

 

http://www.h-o-alternators.com/otherpart.htm Here is the pulley section.

I think ours are only 85 or 90amp, but 4rth gen is 110amp alternator.

Brian

 

well the amp i got right now is 250 watts, i'm fixin to upgrade to an 505 watt rms amp, plus a 100 rms for my front, and that 250 watt rms will be for my back speakers, so either a battery, or a cap will definently be needed, but i know my alternator is getting slammed big time already

 

What kind of voltage problems are you having? You are saying you are having problems with 350 watts?

I have a 1000 watt rms amp and a 300 watt rms amp and I don't really need a high output alternator.

Maybe you just need a new or reman alternator.

 

prolly just need a new one, like, when it hits or any bass my lights dim way down and my rpms at idle will fall to 500or lower when its up

 

I have very similar problems right now but, I also have alot more power. And that power isn't fake power by any means.

Puting stress on the alternator, regularly, over a long period of time can make it weaker. When my alternator was in great shape the lights would hardly dim at all (even without my cap) but now it's alot worse.

I just ordered a reman alternator from internetmart and I will probably install it this week. I will let you know if it makes a huge difference or not.

 

How long was it before your alternator went bad? I just put in two JL 500/1 and was worried about lights dimming but it didn't happen that bad but now I'm worried over time it will. Would switching to the 4th gen alternator be an easy or difficult thing to do?

 

I've had the system in there for about a year and a half and the alternator still works pretty good but it doesn't work near as good as it used (at least it seems that way).

I think it's best to get a cap asap because it'll probably make the alternator last a while longer.

You should be fine for quite a while. Just don't beat on it all the time.

I don't know if a 4th gen alternator will fit or not but, I would think it would take quite a bit of modification because they are completely different. I could be wrong on this but, I think the 4th gen only has two belts instead of three.

 

The mounting points might be similar, and you can switch pulleys if you need to.

Brian

 

the VE alternator looks like it physically can be swapped with a VQ alternator
but the VG uses straight across mounting points so it doesn't look as a particularly doable swap.

VG alternator:

 

VQ has a 6-rib pulley, so you will have to switch to the 4-rib pulley and perhaps change the harness connector? im not sure if Nissan made them universal on their alternators.

Mine was pulled from a Silveraldo. No idea what the amerage is. But it's frekin big.lol.

 

Hi,

which year Silveraldo did it come from?

 

:

 

Not to sure acctually My father inlaw did it for me when mine died last year. To me it acctually looks like its the same size mabey a liitle biger.

 

The frekin big part was just to be funny

 

105 amp then probably.

 

If your alt cannot support 300W or 500W, you got a problem. Most probably your batt negative chassi grounding point is oxidized and/or alt does not get good GND via oxidized installation brackets. Check batt negative cable, add a new alt gnd wire before your voltage regulator blows: http://www.cardomain.com/memberpage/748507/10

 

so basically wiking, what youre saying is, if i add another ground to my att it should stop diming the lights?? or at least help some?

 

After five yers theres a high probability that the alternator assy aluminum has been oxidized to a point, that electrical connection to engine block is bad. One could clean the engine and alternator and add contact grease there. Or just add a new gnd wire.

When (if) that connection is bad, it will cause the alt to 'float'. This will burn the voltage regulator in the alt. And later, battery will die.

If the proble exists, will help. Cheap to install anyways. Add micro tip contact grease to alt connector contacts also.

Battery negative cable: The main ground point is under battery, under batt tray. It is (99%sure) somewhat oxidized. In fifteen yr old nissan might rot off alltogether (mine 2gen did). Clean, add contact grease, tie rubbertape all around (not between contacts).



Both jobs are relative easy, and could be the cause of your problems. If not today, one day the will...

 

alright i'll get outside this afternoon and check it out, hopefully that'll work, thnx for the advice wiking

 

When you buy one get an Autolite, they have a lifetime warr. Buy a grounding kit off ebay, it should help, I'm running six amps well over 1000w with no problems, buy a optima battery if you don't have one.
