Sweet! Good job. Now just gotta find the bare stud somewhere behind the carpeting that they were supposed to attach it to. Just needs to be a stud that is not painted and is attached to bare metal. It’s gotta be close by so you should be back up and running soon.

NVX Amp Power Issue
- Thread starter smilepak
- Start date
If I recall, there is a bolt already in place that is suitable for grounding. I think (but I cant recall) its the one I used. I installed my sub/amp over on the drivers side. When I lifted up the carpet to expose the area over the rear wheel well I believe I grounded somewhere under that area. I think.

You can use any hole on the Frame. The Frame of the Car is basically one big ground cable. If you check the 12 volt battery you will see that the negative post just connects to the frame of the car.
Just make sure that the connection is very tight. A loose connection can cause high resistance and cause issues...

Thank.
Connected to the car body frame right below the carpet. To bar that separate the middle dip and right pocket.
check meter and now get 12v power when test red on 12v and black on ground at the amp screw. Amp still not on. I wonder if I need to connect the ground to one of the screw that is connected to the main car ground. Will try that this weekend.

I f the Battery is grounded to the Frame (which we know it is because the car will not power up without it). The Amp only needs to be connect to the chassis/frame. If you are now getting power at the Amp, it is either not seeing a signal to Amplify or you have an Amp issue, one if the two small fuses on the Amp are blow or the Amp is dead. Do you have music playing in the car when you are looking for Amps lights to come on? Many Amps will not power on until they see a signal to Amplify.

Make sure the gain knob is not turned all the way down. With music playing (like @MikeHolliday said), measure the remote terminal to ground and see if you have 12v there as well. Sounds like the amp is off for sure.
I guess both of you might be right. The amp might be dead lol. After all of that.
I reconnected the ground and tied to the bolt that hand ground wires to it. It the same bundle that ground the lift gate.
meter test red on 12V and black on ground at the amp screw, I get around 12-14v.
then test red to remote screw and black on ground screw, zero
So at least confirmed power is coming to the amp input.
the two fuses inside the amp are both good
so at this point either amp is dead or no signal to turn it on.
I traced the line from the amp input back to the front of the car under the glove box, there is a converter of some sort, it show it has power and there is a glowing red light. I have not traced where the remote line from the amp goes to yet.

Ok finally fixed the issue. This has been an interesting process. Much thanks to everyone helping and pointing to the right direction.
first issue was the ground cable was not connected. So finally connected that.
Then when tracing the remote line back to the car, the converter was not fully seated in the socket. I guess when they replaced the MCU, the didn’t reseat it properly.
Now I get base again!!
Yay!!!!!

Before declaring the Amp dead. Take your volt ohm meter and set it to the lowest DC voltage. Turn the gain up on your display so that you should be getting an output. Check the voltage across the 2 inputs for your signal. It should be reading a few volts.
Do you have a computer Speaker? If so, instead of sending the inputs into the Amp, the tip of a miniature phono plug is Channel 1, the first barrel is Channel 2 and the ground is the closest barrel to the cable. You should be able to hold one wire to the tip and one wire to either barrel and get some if there is a signal...
