Tacoma Sound System! PT.4 BIG 3/4 Upgrade! + Battery Terminal Upgrade! 

For anybody who's gotten to where you need to attach the alternator wire/lug but don't have a 90° lug like this feller- with a little elbow grease I was able to bend one of the pure/100%OFC lugs that came w the kit I have..... Ps thanks for this! Was having a massive brain fart and the diagrams that came w my ISO and big 3 upgrade don't show it. So yeah. Thanks!

The Big 3, in my opinion, has to be the most overlooked part of any car stereo install. It's really not 3 though. It's more like the Big 5 or 6 depending on the vehicle. Even if you do not have a stereo system in your vehicle but do have aftermarket accessories that use electrics, you *NEED* to do the Big 3 mod.

I recommend upgrading your lead acid battery to an AGM. Better power output!

Just upgraded my terminals and got the same cable for my extension. Great job!

Dude that was the best fucking video of upgrading the big 3 genuinely good job explaining it!!!!

Great job and explaining how to do it custom work

Bro next level stuff! Loved the series!

Very clean, very neat and very good looking work! 👍🏾🎯

Have you consider putting up links to the tools and gear you use in your project?

Dude we need a demo!!! I want to hear what the bass sounds like cause I’m getting ready to copy this build for my taco 😆

great system very clean

Ok I'm back.. the + wire that comes from the fuse box... That's just the "other side" of the alternator wire right? Could I just skip the whole fuse box, attach my own as if it were a sub, call it a day? Or will that mess w CE light maybe?

Great video! Could you post links to the items you used.

Amazon has new high intake ear drums too

he fuse does not protect the wire

Man who is this guy

Hey you should help me do a install on my Tacoma !?

Awesome video. What size ring terminals and loom did you use? Thank you. 👍

What if you just run a new wire from your battery to your alternator and just add a fuse?

Couple comments/questions - can you discuss the inline fuse added? And can you explain the part about extending the starter cable why that was done? Also, did you keep the factory starter cable for some reason or just were only worried about the car audio side of things? Great video and excellent craftsmanship! One thing I do is tin all the leads before crimping on a connector, and also put some dielectric gel just before heat shrinking. I am in a coastal area with high humidity and salt and it keeps it uncorroded

Do you have a link to the parts and tools that you used..thanks!!

Need a video of finished product and play couple songs

What was the length of the positive cable from the alternator? And how much wire did you use all together?

What was the high output alternator he used?

so how are you liking the bass from those shallow woofers?

Awesome !

Part 5?

Agm or lithium main battery is a must w that low power lead acid your losing a lot of power and system life.

Yessssssssssssss

Too much work and no sound difference, good job

Asap!!

Wow bud that explanation is so wrong. First off the fuse should be closer to the alternator. Second because the alternator is the supply the wire isn't protected from fuse to the alternator ( so shorter run from the alternator to the fuse ) Lastly I put it this way if you alternator wire has its own fuse factory then you would do that for your big 3 ether way your put loom/tesa tape/heat shrink on all wires on the outside of cab. You always leave the factory on for many reasons, short explanation the added wires just give you a easier and faster flow of maximum amps/ voltage. ( the big 3 is the alternator + to battery + motor ground to chassis and battery ground to chassis...... the 4th is the alternator ground to the battery. If you don't know what that is then you shouldn't be doing this! ( it's the mounting bracket bolt for the alternator).
