Speaker Restoration

This shouldn't be a surprise.  The Speakers are Blown...  Well, you take old speakers, and play them loud you're gonna get shredded cones.  Monster Truk is 16 years old this year, and the speakers show it.  The plan is to maintain the acoustic properties of the mount, and replace the speaker with a right size speaker.  Monster Truk has Premium Sound, that is what I want to preserve.

The front door speakers have a kicker box that seals it to the door frame.  This allows the bass frequencies to travel into the door, distributing the bass sound, so it fills the Truk.  This is what it was missing before because the seal was broken, the cone suspension.  The old speakers had a plastic frame, and were glued into the kicker box.

There were several plastic mounting struts that supported the magnet in the middle of the kicker box.  The the cone, and voice coil were supported by the ring around the periphery.  I used a large pliers to break the plastic struts, and then a chisel to cleanup those areas.  Finally to mount the new speaker I fabricated some small wooden anchors that would fit in the small gaps around the periphery of the kicker box.  This is the carnage of removing the old speaker.
