Let the disassembly begin!

The Pulsar had an interesting audio system installed when we bought it, consisting of an aftermarket head unit with CD player and a single center-channel home theater speaker laying in the hatch area.

In order to remove the remnants of a previous aftermarket stereo installation as well as discover any surprises, I began to remove the interior of the Pulsar.  The head unit was quite easy to remove, a trait of the 80's and 90's Nissans.  The stereo wiring wasn't hacked and instead used a wiring harness adapter as part of the installation which was a pleasant surprise.

The stereo wiring harness was still intact!
The disassembly continued with the rear seat and panels.  There were some severe cracks in the rear corners and some of the mounting tabs were broken, but the plastic panels were still very pliable and didn't feel brittle; perhaps the breakage was due to the stereo system previously installed.

After removing the seats and panels, I was able to get a closer look at just how severe the cracks were in the rear panels.  I definitely had some plastic welding ahead of me!

I was able to inspect the rear speakers at this point.  The wiring to these speakers looked to be in good shape which will save me a lot of time.  The factory speakers, however, were completely disintegrated.

Using my plastic welding kit, I repaired the cracks in the rear panels using stainless wire mesh to reinforce the damaged areas.  I also restored the missing mounting tabs before wrapping up this repair.
