I did the install on mine, which was very easy. The only hang-up was finding the right size Torx bit to get the rear passenger seat belt out. Otherwise it's all about routing the wires and removing / replacing parts.
As for the sound quality, I was surprised at what it could do with such a small driver. I found that the best balance for sound quality was to use the Front to Rear fade control to put roughly two-thirds of the sound up front, and then using the bass control to tame the sound. The Mopar sub has a control of its own, but you can only use it when the sub is removed. Dumb? I turned the control on mine all the way down, and the amount of bass produced with the bass control on the stereo turned all the way up is overpowering. I can't imagine one needing to turn the control on the sub upwards.
The sub adds a great deal of warmth to the music, and easily competes with highway road noise. Its greatest perk, in my opinion, is that it's invisible. The only thing you lose is the tiny cubby-hole that existed.
I personally like the depth that a larger speaker can provide, so in the future, I could theoretically gut the Mopar sub and re-create it with a bigger speaker and new amplifier. (I go more for sound quality than quantity.)
I think the sub should really be cheaper, but that's the point of OEM accessories...markup dollars for the seller. Oh well! I still like it for what I want.
