I simply swapped out my headlights for LED lights, added a cap and no more voltage drop / dimming lights. Swapping out your halogens for LED's take a lot of load off the 12v system.

Well done man! I know a black 4g wire would make it look cleaner for the alt. But understand that is how the kit comes and some people prefer to keep the positive wires red. Anyways love the video, and see you next Tuesday.

[@ExtremeDailyDrivers]

Yeah, wire is wire it doesn't matter what color the insulation is, but I always like to keep things legit when it comes to the electrical system. I don't want to confuse anyone.

I used to have some 8 ga. Wire laying around and I always meant to see how the wire would work out well enough

Cool upgrade man, kicks up the box and on a budget! I was thinking after yesterday's M M vid that perhaps you could do a T T vid on re teaching Mrs. XDD to drive stick shift on the box.

I’ve always wanted to do the big 3 upgrade to my xB but could never find any solid info on how to on the xB platform. Great job man, looks great! HOWEVER you should 1000% put a fuse on that alternator cable.

[@ExtremeDailyDrivers]

Thanks! I had the same issues finding solid info too. I still believe the fuse is optional, but it's your car, do what you feel is right.

[@MrMonro27]

My xB is getting a little old now lol and I’m thinking doing this is a great idea, especially because of my stereo system. I’ve been noticing more of a drop in RPMs sometimes depending on what type of music is on, so this along with the system the way it is might improve things a bit. Bad grounds are the cause of a lot of vehicle electrical issues, so this is def something that can only help, if not improve.

[@ExtremeDailyDrivers]

Go for it!

[@chrisbellevue]

Under your hood looks kleen asf! Thanks for this vid. Now I need to buy some wire.

[@ephraim.1964]

Man I just started doing some work on my 2004 xb...mainly tune up. spark plugs and coils pack, Oxygen sensors up & down stream,, camshaft, max airflow, Solenoid. every was good and smooth until I got to the throttle body IAC 2 vac house. The must uncomfortable throttle body I’ve ever worked on. there’s hardly enough room to remove those house clamps and the vac house were like glued on to the IAC. Talking about time consuming and frustrating process. Mind you all sensors were the originals and my car has now 297,500.

[@ExtremeDailyDrivers]

Yeah, that TB is a pain and that's partly why I haven't upgraded it yet. Thanks for watching.

[@bda2672]

Good video bud, has more potential. I'd suggest 1/0 audio cable, or 2/0 welding cable, for this application. I'd suggest investing in a hydraulic press ($40-60 on amazon) since you appear to do this often enough to invest in one. This way you can properly press any gauge wire. I'd also suggest to invest in a drill/driver steel brush attachment to peel away paint from area you bolt to. Then cover up with some sort of rust proof silicone paint. This way you get pure metal contact on your bolt spot. You can also get multi spot SAE terminals to place multiple wires on a single terminal for your battery. Last, but not least, for the life of God upgrade your battery. That walmart brand won't help with heavy electrical. Upgrade your car to a XS Power battery or a Northstar battery. Overall a good video and your car deserves it plus you'll thank yourself with all the electrical demands. Cheers!

[@ExtremeDailyDrivers]

All good suggestions! Thanks for watching.

I was thinking the same thing it’s like he didn’t do the big 3 battery northstar are good battery’s all where s the alternator upgrade it needs to be much bigger

I am getting my grand son 2004 xb, it has been sitting outside for 6 month and nothing works on the dash or doors and I am summing it lost a ground for so many things to fail. All these systems work before he parked the car. I will upgrade the grounding first, we checked fuses and all were good.

What’s going on brother. Just wanted to say huge fan of Toaster Tuesday. It has definitely been encouraging me to put a lot of more work into my box as well. I’m actually putting the system in 2- 10in subs with 500watt amp, as well as an amp for all my speakers and deck. I’ve been reading in the comments about how using 1/0 instead of the big there kit would be better. What do you suggest?

[@ExtremeDailyDrivers]

Would it be better? Technically, yes. Is it necessary? Absolutely not. Especially for what I'm going to be running. If you want to install 4 1000 watt amps powering 4 12's, then I would upgrade to 0/1 gauge. Otherwise, what I did is fine and still working great. Thanks for watching!

[@box_boi_howard]

Ok sounds good. Because I have the normal size battery as well as putting in a capacitor. I don’t plan on going any bigger in size on the system. Appreciate the help the brotha!. Ive been doing a lot of upgrades to xb as well. Can’t wait to share it with the BOXFAM

[@box_boi_howard]

Ultimately how many grounda should I have connected to the battery after doing the big three??

[@ExtremeDailyDrivers]

The same ones that you had when you started plus an additional ground. Thanks for watching.

[@box_boi_howard]

I had two when I started but they were messed up. One was to the transmission and one to the frame. So did the big three and replaced the original ground to the frame. That’s that’s to ground to the frame and one to the engine. Do I still need the one goin to the transmission??
