Wrap paper around your "Pyramid Car Amplifier". It will then be the shape of at least your "pyramid"! :)

PPI made those in the late 80's and 90's. There was a supply chain issue. They never really got popular.

This more than likely means that you have a blown fuse. Go to an electronic store and replace the fuses. Make sure you get the exact same sizes and types that you had before.

Figure out if its a blown coil or damaged cone

1. Blown Coil:

The voice coil is the component, which amplifies the current run through the speakers. If you doubt that the coil is damaged, connect the terminals of the coil to a multimeter, and if there is no resistance detected, it could be because the coil is damaged.

2. Damaged Speaker Cone:

If there are no issues with the coil, the next possibility can be a damaged speaker cone, which can be detected easily. In normal condition, since the subwoofer is built on a suspension system, the cone is easy to move. Look for the following signs to understand that your speaker cone is damaged:
  • If you could gently take the cover of the subwoofer off and check for the movement of the cone by gently pushing along the sides
  • If the cone is rigid and does not move its indicator
Once you make sure that you have a blown subwoofer, the next step will be deciding on how to replace it. Imagine if your subwoofers can be fixed easily with minimal efforts within a set budget rather than buying a new one.


1. Detaching the speakers:

Use a screwdriver to take the speakers from the place where it is mounted and take off the attached wires. After that, separate the surround and the frame by removing the glue on the frame edge by using a small knife or a sharp object like a tester edge. Be very careful when you do this because the frame edges can be damaged.

2. Separate the voice coil and speaker cone:

Using the same small knife or a tester edge, slowly take out the voice coil from the speaker cone. Cut all the terminal wires and keep the voice coil, speaker cone, and spider separately in place.

3. Fixing the new voice coil:

Clean the trapped dust particles in the voice coil gap carefully by using the compressed air. The voice coil is the piece of wire that is attached to the speaker cone, and that is responsible for amplifying the current, which is passed through the speakers. Remove the old voice coil and fix the new voice coil within the space if the problem is with the coil. Place the spider around the new voice coil, replace the spider and then the speaker cone in the middle. Don't forget to apply enough glue so that the cone doesn't come out. Let it dry for about 24 hours.

4. Fixing the speaker frame:

After it is dry, apply glue on the surround to fix the speaker frame and the cone in the right position. Now we are about to reassemble the components of the sub-woofer.

5. Fixing the wires:

Once all the components are put together in the right place, use a soldering iron to connect the old terminal wires with the new voice coil terminal wires, if the voice coil is replaced. If the new cone has no pre-attached wires, use small wires to the terminal wires, and then create small holes in the cone. Place the wires into the holes and connect them to the voice coil using the soldering iron.Now the connection is also reestablished.

I have the same problem with a 2010 Murano. It doesn't happen in the winter like you said. It has to do with the air conditioner or with humidity. I just drove today with the AC off and the problem went away. It could be a power problem or a moisture problem.
