Installed Subs and Amp and now truck has zero power

Hello, I recently installed my subs and amplifier to my truck. After installing everything, I go to start up and the truck turns on then immediately shuts off. It then has zero power to ignition. I checked all the fuses and all fuses are good. I double checked my wiring and everything is good. The only connect I’m unsure about is the remote wire that I tapped into the stereo but I did the solid blue wire. I don’t know how to further troubleshoot this.

 

Was the battery weak when you tried to start it? The remote wire should run from the amp to the dark blue wire on the head unit. As far as I know most head unit manufacturers are blue and usually has a remote label on it as well.

 

Battery is at 13V but I’m charging my jump pack just in case but I highly suspect it’s not the battery.

The wire I tapped into was the darkest blue wire and solid. It was not labeled because the previous owner cut off the tags.

 

What headunit is it? Now that I'm thinking about it, the power antenna is a blue wire as well. Does the amp turn on with the wire that you are currently connected to? Is the truck turning over and it just won't start? What year is it?

 

The truck has zero power to it. Almost like a break from the battery to the truck. The head unit is a boss stereo. I don’t know the actual model number

 

Undo everything

 

What year is the truck? The 14 and up is very sensitive to electrical changes. That's why everyone says to disconnect the battery. Was the battery disconnected during the install and is the amp power wire ran directly to the battery? I beleive there is a main relay or fuse is the positive cable and it's possible that it may have fried. If I recall correctly it's in the bottom of the fuse compartment and PITA to change.

 

I did not disconnect the battery. It’s a 2011 but I ran the amp power wire directly to the battery with the fuse attached to it. As far as the main fuse, it’s under the fuse compartment? How can I test it to see if it’s good?

 

Pull the fuse box and visually check it.
You really fucked something up if the truck won't start.

What else doesn't work besides starting the truck?

Where did you tap the 'remote' wire from the truck?

Welcome to the forum..

it's too late for that..

 

There’s zero power to the truck so somewhere between battery and ignition, there’s a break in the system.

 

Check the battery connections and grounds

 

You probably blew a main fuse.
As @eddiefromcali stated, disconnect the power (probably the remote) to the amp.

Pull the fuse box and look at the main fuses under it.

 

Good idea.
Make sure they are free of corrosion.

 

And replace the boss as soon as you possibly can…..

 

That's a given....

 

Trust me, I have another 10” deck on its way. Boss is garbage

 

I’ll go ahead and do that tomorrow and update everyone. Thanks for the leads

 

So I got 2 used fusable links and replaced it and still zero electrical to truck. I tested continuity to all fuses as well as all 3 disable links. I took out the whole sound system and went back to its original state. I’ve had no luck today troubleshooting the issue

 

Ok. Did you check for voltage at any point? You need power for anything to work.

Everything is dead? Your problem is going to be near the battery connections. You don't have any lights on at all? No dash, security, interior lights, headlights, nothing works?

 

No lights at all. I checked battery voltage and reading 13v. I even went to the local parts store to test the CCA and it’s good.

 

Ok so the battery has juice. Did you read voltage at the fusebox? Any of the fuses?

 

I did not read voltage but I did test everyone for continuity which they passed.

 

Yeah but your problem is you dont have any power. Check for power. Start at the battery and then the under hood fusebox next.

 

How exactly do I do that? Run a multimeter for voltage from what to where?

 

As @Half Assed said, take a multimeter and check for power (continuity is just telling you that you do not have a break in whatever line you're testing). 1st start at the battery by putting the red test lead on the battery positive and the black test lead on the battery negative. You should read approximately 12vdc. If you do not, then your battery is probably dead and/or bad. If battery tests good, then I would move on to the alternator and starter. Place the positive test lead on the positive input post of the alternator/starter and the negative test lead on good structure ground (you need to check the alternator and starter independently of each other). Both of these should read tnhe same as what you read at the battery. If your readings have been good so far, then the next step I would do is start checking fuses and relays in the main fuse/relay box inside the engine compartment. I assume you have zero power when you turn the key to accessory, right? I say this because you posted you have ZERO power to the truck. If this is a misunderstanding, then before checking the fuses and relays I would use the multimeter to check for 12vdc accessory power at the remote line from the head unit. If you miraculously have 12vdc power at the remote line, then the problem most likely lies somewhere from the head unit and/or forward (HU to amps to speakers. You will just have to work your way forward checking each line for 12vdc if it's a power line, or continuity if it's a signal line). Back to the remote line....if no power reading with keys turned to accessory, then problem most likely lies in the fuse/relay box and you'll have to start checking through them. I personally would start with the main power fuses and relays.
Hope some of this helps....

 

So I did not check the voltage throughout the system but when I say there’s zero power going to the truck, there’s literally nothing, not even the dome lights when I go into the truck. With that being said, I don’t think the start or alternator is the issue. It would have to be either the battery, which I checked and read 13V, the wires running to the fuse which I checked only with continuity, checked all fuses and replaced main fuse, then from there would be the ignition switch. But the key factor is I hooked up my remote wire accidentally to my antenna wire and I stumbled across something that says the antenna wire is connected to the ignition switch. My problem is I don’t know how to test the ignition switch because I can’t find a diagram that shows color wires and description

 

Ok, if there is no power getting to the whole truck, then you’ve got one main problem that should be easy to find. You either aren’t getting power (the positive post of the battery) to the main fuse box, and on from there (bad fuse, loose connection, corroded cables) or, you aren’t getting good ground return to the battery to complete the circuit, typically bad ground connection or corroded battery cable. Sometimes things happen coincidentally, more often than not, Occam’s razor says that the most obvious answer is usually the correct one. You probably blew a fuse by shorting something out when you were connecting those amp wires, or you disturbed a corroded cable making those connections and it is no longer making good connection.

 

I’ll double check all my wiring. I did check all every single fuse for continuity and even changed out the main fuse. I suspect you may be right with the cables because the previous owner had some sort of electrical fire near the fuse box but the only thing that burned was the protective cover and a few power cables but no exposed wires. So maybe after I overloaded the system, the wires finally gave out or the ground is not contacting good.

 

You left out the previous electrical fire part

 

Yes but like mentioned, nothing besides the cover and power and ground wire showed signs of burns and the wire burns were slightly on the insulation. My guess is he shorted the positive to the ground wire and fed power directly to it thus causing the wire to heat up and burn the plastic cover. But that ground wire could possibly be the issue as you stated. I don’t have any wires thick enough to replace that so I’ll just find the thickest one and try to jump it.
