Big Three upgrade?

Has anyone done a "big three" electrical upgrade? A lot of audio folks do this (and many people say it is a waste of time too unless huge watts) and there can be a measured improvement to the amps performance and it is relatively cheap. I have an audio system that is at 800 W total, though never pulling that consistently, or even close.
It consists of:

This upgrade replaces or augments three key cables in the electrical system with 1/0 or 4 gauge wires: the battery ground to chassis wire, the chassis to engine block wire, and the alternator plus to battery plus wire.

I am wondering if there is anything I should watch out for in doing this. Some put a fuse between the alternator and the battery, not sure if that is really needed.

Where would be good spots to attach the wire to the engine?

 

You may want to ask over here, in the dedicated "big 3" thread: https://www.tundras.com/threads/04-sequoia’s-150-amp-alternator-swap-on-a-00-tundra-the-3-big-upgrades.67222/

You only need to fuse/breaker circuits on the positive side of things, and ideally within 18" of the battery.

 

Thank you sir. It is mentioned in the thread that a fuse on the + side is only needed above a certain amp rating. Thoughts on this? Better to just put one in?

 

If you do go that route, @shifty` did point me to this site:

I plan on doing it once my install comes to fruition.

 

That looks like a nice kit but seems like more length than needed.

 

Probably. But I'd rather it be too long than too short.

 

the cables from CE are much better. i got everything i needed for this upgrade from them. haven’t used anyone else for electrical cable in the truck. stereo, solar, dual battery, etc all came from them.

Custom made cables? Nice! That could come in handy. Bookmarked.

 

Heard nothing but positive things from CE, but there's also someone on one of the forums that knocks out proper beefier cables too.

 

That’s what she said!

 

Hey @bmf4069 did you upgrade your Big 3 upgrade stuff? if not I can help you with doing the big 3 upgrade. If you can help me with the cable lengths then I make customized 1/0 cables of good quality.

I do that for Toyo Land cruiser/LX already. The price would only be cost plus shipping for you since I am looking for a Gen 1 Tundra truck to work with me to get the measurements correct for the kit. I kinda have an idea but getting exact lengths is better..

if anyone other member wanna give it a shot as well hit me up via PM.

 

You got it, neighbor!

 

If you’re still doing the big 3 kits I’d be interested in one for a first gen tundra.

 

@bradbystereo send you a private msg. Thx.

 

I love the argyle cable jacket!

 

Heya, checking in on these kits. Looking at upgrading the 180 amp alt.

Please lmk about the cabling. Thanks!

 

Send @baraynavab a PM.
