I've been tinkering with the stereo in my 2004 kermit. About 6 months ago I purchased some MTX terminator 4x6 up front and 5.25s for the rear. I blew the rears already! Lack of bass and shrill highs made me adjust the bass too high on my head unit and kill the surrounds.
Last week I ordered some prime 6.5" RF components, fiber fill and closed cell foam baffles for the rear speaker pods.

I apologize for the condensation as spring time in PA has it raining in my jeep with condensation! Anyways, I then wanted to make sure the speakers weren't working against themselves so I then pulled the head unit (installed by previous owner) to check polarity. I found a surprise! Behind the alpine head unit was hiding a little gem of a unit.

That is a nice little 4 channel amplifier designed to boost the output of the amplifier. I'm wondering if the over excursion of the rear speakers was due to too much powa! I cleaned up the wiring harness and re-installed it on top of the left vent tube under the steering wheel. hopefully this fixes the random rattles behind my dash as the previous owner used double sided tape which doesnt exactly stick anymore. I chose zip ties to attach it to the top side of the vent tube. Next week will be a good week for further improving the TJ's interior. Im adding storage and a little sound deadener (by design) to the rear cargo area.
