[@fosholyfe6115]

@@jsil88dog if my info is correct, you don't add a second battery.. This is one of the reason for a 2nd alternator in my car, so i wouldn't have a 2nd battery being charged by just one alternator.. I may be wrong but i believe its either 2 batteries vs one alt or 2 alternator vs 1 battery.. Alternator num 2 runs audio independently therefore not draggin on engine performamce ECT.. Im learning.

@Rob James 140db will destroy your ear drums if it's something like 3000hz. But low frequencies don't really affect ear drums. You feel it in your body which can handle much much db than ears can.

one question, if you dont conect the 12v wire to the alternator (the blue wire), what could happen? alt wouldnt put out max amp or it wouldnt even work?

[@MrMellSmith72]

Are both positive on the alternators in parallel so that you get higher amps at idle or are there separate, factory alt for trucks electrical and HO alt for system?

[@buffalobenno6256]

As an old electric-mekanic working at Scania-trucks in sweden we mounted double alternators in the trucks because they got more and more of gadgets that need electricity.But that seams foulich to do it så complicated as in the video .By that time it was just 35 amps each alternator Times24volt it makes 35 X24 =840 w.This was in the 1970:ties.

you wont overcharge your batteries like this? i always ran extra alts to a switch. especially ones that just put out 14.8+ all the time. stock i left the same.

[@MrTheHillfolk]

goldeneye4564 Voltage regulator is gonna regulate voltage , if the batteries have 14.8 then the amperage drops off. To me yea , 14.8 is on the high side , 14.5 is plenty but it’s not way out of range , it’s not gonna be popping bulbs or anything.

[@BestPlconEarth50]

Hey guys nice job system sounds real good I did something similar to your power upgrade and still found out I was having a bit of fluctuation like you have, I was able to remedy the problem with a n additional battery. I use a group 31 battery that has threaded post commonly used in semi trucks.

[@robecho2901]

John Smith why there is no fuse in between alts and battery and a fuse in the back battery ? get back to me whenever you can thanks

[@BestPlconEarth50]

+Rob Echo Typically there is no fuse on the alt to battery wire because of the length which is short and its minimal routing through the chassis, also the alternator output can fluctuate a lot and sometimes you will see really high spikes. You could put a fuse on that link just be sure its probably 20 percent more than the rated output of your alternator. For the other part of the question its a necessity to use a fuse as close to the battery as possible when running any wire and not just the original battery you need a fuse after the oem battery then another fuse as close to the additional battery as possible then another fuse on the load wire of that battery. This assures that you will never have a shorted wire along the length of the run. If you were to short the wire from one battery to the other and had only one fuse the additional battery would short unless you can safely cut voltage to that via the second fuse. That is a pretty windy answer but I just wanna run home how important it is to have a fuse along any run without one you are more than likely to catch the vehicle on fire with a source more powerful than one of those silly fire extinguisher can extinguish. I don't know who said this but any thing than can go wrong will. Have a good day buddy.

[@stanleytgbolojr.8016]

14.8 v is that a heathly charging voltage for that battery??

[@nathanmathews8416]

How did you get both alternators to put out amps? Typically only one will put out power until its maxed out before the other steps in.

[@paulplack490]

It looks like the sound system is on a completely separate system with its own battery bank, independent from the vehicle's 12V system. The two alternators don't even "see" each other. The only things they have in common is ground and the ignition sense line to allow the aux alternator to start when the engine is running.

[@chrispy725]

I think that guage just has one connection for positive and one for negative. You can run the negative wire to the battery or a good clean piece of metal. The positive side needs to go to a fused positive source. You can run a wire to the battery but be sure to put a fuse in line with the wire a 5 amp fuse should be enough.

[@AP9311]

Mr Lazy the big amp alternator had a bigger rating at idle, when revved up, the output goes up. Stops the engine from dying when the bass is playing. I did that on my suburban. I have two alt and two batteries, fused on all of the wires. I can play my 4 12s, 4,000 watt all day long. The alt output won't ever drop below 14.2 volts ever.

+Jesse Gunderson whats up man, whats your make model year and motor size

[@IFartOnMyNutz69]

If you're just running the 1 alt, get a 400 amp alternator. Paired with 400ah battery, then your system will support a total wattage of 7920 watts. Your stock system uses some of that wattage, so running 6k to 6.5k watts on amps should be perfect match. You'll get more juice from running dual alts though, especially with 400ah of battery you already have

[@circusboy90210]

how much more resistance is that on the belt when producing full power?

[@paulplack490]

@ circus, 3500 watts is about 5 HP, and the alternator is likely in the ballpark of 50% efficient. So the extra load on the belt could be as much as 10 HP.

[@MarkKoolen]

What is the reason you go with 4 wires to that metal block, and then go forward with 4 wires instead of connect the 4 wires direct to the strip on the aternator

Rob Echo I'm not sure why, but most guys doing these videos don't put any fusing on their power leads.
