Yep, inline barrel fuse. Looks like this one

Amps use the RCA wires for the sound signal so you just need an amp and a sub.

Like the other guy mentioned, the blue is just a 12v signal. When the head unit turns on it just sends 12 volts and the amp turns on.

You'll need a short amount same gauge wire as the red wire to ground the amp to the chassis. The electricity needs some way to get back to the battery. I bet if you look around under the carpet to the side you'll find the ground wire bolted somewhere to the metal under the carpet or along the side.

Like /u/cancerous_anus said, definitely check along the red power wire, probably under the hood, for a fuse. If not most definitely put one in. Get something like this. They use the old style glass fuse.

No. Do not order and use a 150A fuse with that 4 gauge CCA wire. This is the fuse holder you should use.

Your previous fuse holder likely melted because either A) It was lying against something very hot under the hood B) You had a poor connection somewhere in the chain. Poor connections cause voltage drops. In any decent amplifier with a regulated power supply, when voltage drops, current increases to give you the same wattage out.

I've never used ANL fuses, and my alternator-charging circuits are usually set up with 100A AGUs. I also strictly use manual isolator switches for my personal rigs, and at times, use both batteries and the alternator to run something big via a 4800W inverter. Never had a problem.

One reason for my choice to use AGUs is that off my aux battery, I like to use something like this, as it yields the ability to swap in a spare from the same collection to any of the places there's "big" fuses.

That said, I do like the design of ANLs, as I could forgo the fuse holder altogether, and build my own fuse panel. I just haven't had a case where that was particularly useful, and I can get AGU stuff in-town, same-day. Nothing wrong with ANLs; they're well-suited to the application. Just be sure you're fusing both ends of that interconnect wire.

It's extremely easy to DIY. I'd strongly recommend visiting YouTube. Most customization shops will likely do it, but AFAIK it's not that common of a task due to how simple it really is to do. There's videos for pretty much any popular car model.

A screw driver, some zip ties and maybe a knife or pair of wire strippers is all you'll likely need to do it right.

In case anyone is curious here's what's involved:

  1. Stick camera where you want it (likely behind rear view mirror as high as possible).
  2. Tuck wire between headliner and roof of car, you can use a little tape if needed, in most cars it's not really needed if there's some tension. You're wiring towards normally towards the driver side A pillar in most cases since that's where the fuse box is, however in a few cars it's on the passenger side. Check your manual it will tell you. Leave a little slack for adjustments by the camera. Just a tiny bit of slack by the pillar.
  3. When you get to the A pillar, there's normally some clips/screws that you need to remove and the plastic trim comes right off. It's made to easily come off. If your car has an curtain airbags they are here, so a little caution is needed. You can remove the neutral cable from the battery to fully disarm if you're really nervous but they aren't THAT sensitive, it's not like they inflate if you go over one of our many glorious potholes. Just don't punch the damn thing. For almost all cars there's a bunch of wires behind the airbag that go down into the dashboard. Use some zip ties and secure your new cable to those existing ones. The important thing here is to keep your new cable behind the airbag at all times, so you don't obstruct it. Just follow the existing cabling.
  4. Tuck that cable down the hole at the bottom of the a pillar and feed it down to where the drivers. You may want/need to unclip some plastic down there by the foot well.
  5. The ground wire can be secured to any metal part that touches the frame. There's always some screws you can remove one and use that to screw down the ground wire. Now you're half wired.
  6. Now the positive goes into the fuse box. Since you almost certainly won't have spares, you'll need to tap something. No worries that's simple just a matter of what to tap. You can find a fuse tap for cheap on amazon or any auto parts store. Note there's different sizes. Your manual will tell you what you need or just ask at an auto parts store and they can look it up. Look in your manual for what is what, you want to tap something non-critical. Obvious reasons. It's normally a table of each fuse position and what they power. For example the radio. Something that turns off when the car is off, but works when your car is on. Pull the appropriate fuse, put the tap in, then put the fuse in the tap. Then crimp the wire from your dashcam to your tap.

    That's really it. All that is a detailed way of saying "thread the wire around your windshield to the fuse box then bolt the neutral to bare metal and put the positive in your fuse box tapping a non-critical fuse that's only energized when the car is on."

>What's the danger of doing something like this?

Building on a pre-made unit with a low voltage output takes away so many worries. So assuming that the ATX PSU stays in good working order..

The biggest danger comes from the fact that the unit will happily pump 100 amps into the right kind of short. As the other commenter said, there may be some short-circuit protection, but there must be some range of loads into which it will deliver that maximum power. Whatever your project was supposed to be, it is now inside-out toaster oven.

  1. Keep it powered off whenever you're not there watching it.

    ​

    >And is there a way to protect from shorting two different power lines?

    Assuming you don't actually need hundreds of amps, I would:

  2. Disconnect all but one of each (e.g., red and yellow) of the power wires. Doesn't have to be permanent, just take the end out of the ATX connector, insulate it, and tie it back neatly. Keep at least as many ground lines.
  3. Put an inline ("pigtail") automotive ATC/ATO fuse holder in each of the supply lines you want to use. Something like (no affiliate) 14 Gauge Fuse Holder ATC/ATO, 10 Packs in-Line Automotive Blade Fuse Holder with 50PCS Standard Car Fuses

    There are all kinds of thermistors, PTC switches, and other options for resettable circuit breakers worth looking into, but you'll never regret having an assortment of fuses handy.

    Now that you've got MOSFETs working in switching configuration, you might look into enhancing your supply with adjustable current limiting.

In your drawing, you want a fuse coming off the 12v DC converter on the red wire before you connect it to anything else. Ideally, you need to figure out how many amps your setup should draw and get a fuse rated for just slightly higher. Your linked power supply has an output of 10amps so no higher than that. Something like https://www.amazon.com/VOODOO-Gauge-Inline-Holder-Fuseholder/dp/B07CXK6MCR/


Also, what /u/SliceofLie said. I would have separate power supplies. One for the arduino and one for the lights. However, if you add the extra fuse the worst case is releasing some angry pixies from the arduino.

u/Rainner32 · 2 pointsr/CarAV

Thanks man after following ur advice, I found that the trailing edge did not give any voltage feedback but the side closest to the battery did give feedback. Running a continuity test I further found out the fuse failed. Whats interesting is that the fuse looks intact from just looking at it. The fuse is a AGU 80 amp 5AG80A
Saying that I have found two problems with my installation that were the likely causes of my issues. 1)I had left the rubber inside the terminal of one end on the fuse holder. There is now a black singe mark inside the terminal. 2) The fuse is a AGU 80 amp fuse, after doing some research I have found that the recommended fuse for 4 gauge wire is 125 Amps. I have went out and bought a new inline fuse holder with a ANL 150 amp fuse.

Thanks for the advice.

u/tscarps13 · 1 pointr/HomeImprovement

Just put a similar setup in my small shed to run lights and a few other things. I put this between the battery and the items i was powering so i could add circuits as needed.

u/ehferking · 1 pointr/SubaruForester

No splicing the factory harness... but it does require splicing into two of the wires that connect to the button. The connectors snap over two of the wires to the button (unless I can find a connector that matches the button connector).

Power comes via an add-a-fuse connector, the ground connection works on any screw / connection to the vehicle body, and the button wires are tapped via snap on T-Tap connectors.

An additional benefit is that only changes the startup state - the button still works to turn it on \ off if there's ever a situation where you wanted it on.

u/random12356622 · 1 pointr/Dashcam

Tap a fuse - 1st fuse protects your vehicle, 2nd fuse slot protects your dash cam - allows you to tap into the fuse, and power your dash cam.

u/beth6han · 1 pointr/Dashcam

I am assuming that the reason you want to hardwire the dashcam is because your cigarette lighter is live all the time, even when the ignition is off. If that is the only reason, you do not have to hardwire it, you can purchase a switched lighter adapter and keep the dashcam plugged in all the time and turn off the switch on the adapter when you leave the car.

I am just saying that because you have not indicated that you are interested in hardwiring because you want to use the dashcam in parking mode, and because you have said that you have no experience in car electronics.

However, if you want to go ahead with the hardwiring, I urge you to watch some videos on YouTube demonstrating how to hardwire. Here's one, e.g. https://www.youtube.com/watch?v=3I9FZL8btqc

As to the fuse to use in your car, I see that you have 3 fuses that are spare. You can use any one of those provided that it only becomes live when the car ignition is turned on. The only way you will know that is by testing it with a circuit tester.

So, along with the circuit tester you will need to buy a 'add a fuse' such as this https://www.amazon.com/HitCar-Vehicle-Circuit-Profile-Holder/dp/B00U61OO50/ref=sr_1_9?ie=UTF8&qid=1468810452&sr=8-9&keywords=Add+a+fuse

Make sure that the blades of the fuse are the same as what is in your car.

Be very careful when working in the fuse box that you don't short circuit anything. It could be bad news.

u/upparoom · 1 pointr/dashcams

I'll show you my setup to see if it will work for you.

Dashcam - https://www.amazon.com/V1-Dashboard-Recorder-G-Sensor-Recording/dp/B00X528FNE/ref=sr_1_4?s=car&ie=UTF8&qid=1484000259&sr=1-4&keywords=dash+cam

add-a-fuse connected to an always hot fuse under the passenger side - https://www.amazon.com/HitCar-Vehicle-Circuit-Profile-Holder/dp/B00U61OO50/ref=sr_1_1?s=car&ie=UTF8&qid=1484000314&sr=1-1&keywords=add+a+fuse

12 volt to 5 volt adapter cable https://www.amazon.com/WheelWitness-Hardwire-Installation-Dashboard-Charger/dp/B00TGQ1Y3Q/ref=sr_1_3?s=car&ie=UTF8&qid=1484000362&sr=1-3&keywords=12+volt+to+5+volt+adapter

Run that to the dashcam, add a 64GB microSD and record at 720p.

You should get around 6 hours of footage before it erases the older one. You can spend a little more to get a dashcam that will support 128gb SD cards and get 12-14 hours out of it.

If you connect it to an always hot 12v fuse, you should have no problem keeping the dashcam running 24/7.

Note: In Texas, temp near the windshield can exceed 110 degrees so make you get a capacitor based dashcam if you live somewehre that gets really hot or really cold

u/gen10 · 0 pointsr/CarAV

Ok so ill be ordering this one.

Could water have potentially gotten to the fuse and cause it to blow? I saw slightly exposed wire where the fuse connects to the wire via allen key that is now covered with electrical tape.
