After being pretty disgusted with the factory Alpine sound and rear quarter rattle I decided to do something about in the first week I bought the Jeep. Unfortunately basically no bass is sent to anything except the sub. The system completely lacks mid range. A good rap of a snare drum should delight the ears.
I'll give a good piece of advice to anyone looking to do anything without a new sound processor or a cleansweep to amps setup. Stay away from metal tweeters and stick with silk such as a full CDT setup. The Polk aluminums do NOT match up to the Focal aluminums at all. I have it sounding way better than stock but it's far from what I was hoping for. I bought the Focal 6x9 components new for $150 which is the only reason I bought them. Polk DB 351 center, Polk DXi rear doors and CDT 8" HD sub.
Here are the focals finished
Here's the rear quarter. What you see on the outside is one layer. On the inside I did 3 layers to every spot I could reach without covering any factory clip
Factory sub out. The box will be sanded with 80 grit and fiberglassed over.
Here is the rear door. The brackets had to be trimmed then form a gasket used to seal the bracket to the door. Also have to add more screws so it does not flex.
