And here I always thought the big three was upgrading the wiring (everything just described) as step one then upgrade your alternator to a high amperage model as number two and finally upgrade your battery as the third and an optional forth of installing a high Farad capacitor to the positive side. But I looks like I was wrong. I mean upgrade the wires without the other two isn't that big a priority as the stock system is set to fully handle the stock output of its alternator.

Can you put the engine block ground anywhere? Or does it have to be on the stock location

Most new cars come with AGM batteries now. My kia Optima has a AGM under the hood so I left it

Answered my question in the first 30 seconds.

What alternator belt did you use on this if you have the part number would be great thanks

[jamesdschlachterjr.]

I understand the reason for multiple grounding points. My question is, why ground the battery(s) back to the alternator?

[irvinvega]

Doing this upgrade will help my battery wattage from going down everytime i turn up my system?

[QaibQusRoobKujYem]

Thank you for showing your upgrade. I still confuse why you use black wires to hook on the battery positive terminal. Very informative video.

Instead of running 2 0 gauge, power and ground each from the alternator to the battery. Can you just run 1 double 0 gauge power and ground each from alternator to battery? Also in these 2 setups what size fuses will you use?

[davidschreckengost]

First off . On a standard system u check voltage at battery and the wiring in the back if your less than .5 voltage difference then your ground location is ok. Second always look for factory ground to run off of. There made to give the best current flow. Inside vehicle you clean each location and use dielectric grease. Fourth by doing these steps you shouldn't need to run wiring all the way to the back, just to much. That's for 10000 watt or more type systems in witch case you running a hole battery bank in back so you won't have to run more than one run of positive and negative to the back. Lastly when doing outside connections after cleaning the contact points use a clear clear coat to protect them. If your going to do the trouble of the ( big 4 ) you should take alternator off and clean the mounting location before connecting wiring and then use the clear coat to protect.

My 2018 Kia already comes with 140 Amp alternator and 4 Gauge wires to the +/-.(200amp Fuse factory) I don't see the necessity of doing this, I'm only running one 12" - 750-1000 watt rms amp/woofer, and 200rms amp/speakers. My lights don't dim at all. Maybe its good for older cars?

[ryancatlin]

How much 0 gauge wire do you think you used for the big3/4? Figuring with 2 batteries like you did.

[hakanwall]

Seen several videos now on this big 3, and all say that they kept the stock cable, but not why, why keep the stock cable I assume a 0 gauge cable can handle the same job as a 8 gauge.

[AngelChavez-fznk]

Hey bro i need help on the big 3. Well i dont have a ground wire from the engine block to the chassy the only wire i have is from. The block to the side.

[TreeGuyTy]

Rather than running the alternator ground to the battery, cause I just run a new ground from the alternator to the chassis? My batteries in the trunk and it’s a pain in the ass to run a wire all the way back there.

[Eleinad]

I have my power ran straight from the alternator to a second battery and then have the amp hook to my second battery I had to take my system out because every time I was at a red light for a stop sign and even if I had the music Low when I would start driving again the truck would really struggle I have a 2009 Ford F150 with two 12in 10000 watts each with a 4500 watt amp I already replace my alternator once and a new battery would I have to still get a high powered alternator or do you think if I just ran the big three it would help a lot more or should I do both? Sorry if my question is a little confusing or a little bit everywhere

[burnrubber]

So I'm gonna do this next to my 08 civic. Only running 1k watt amp, 2100watt sub. I was told if I run a 0 or 1 gauge I would have to upgrade the alternator is this true?

[Fatboy]

Really enjoying your second channel and the knowledge.

[BEAZY_]

I have my ground for the alternator from bolt, grounded to the strut tower bolt and reads 0 ohms, does that make a difference not being grounded to the battery directly? Does that cause a ground loop?

[cyborggaming]

Is it a good idea to also have a smaller pulley on the high amp alternator?
