OK, nothing too fancy here. This is what I put in my 2010 Forester 2.5 X premium (MT). I wanted a great sound system without having a sub in the rear (by order of the wife). So far it consist of:
Kenwood eXcelon KDC-X791 - Head Unit
Precision Power PPI 356CS - 6 1/2" component speakers (front)
Infinity Reference 6022i - 6 1/2" coaxial speakers (rear)
MB Quart DSC 480 - 4 channel amp (RMS @ 4 ohms: 80 watts x 4)
Kicker TCVT84 subwoofer/enclosure (200 watts RMS, 4 ohm)
I'm running the front component speakers off of 2 channels of amp and the rear coaxials off of HU. I'm bridging 2 channels (320 watts RMS) to subwoofer under passenger seat.
The rear area with amp, crossovers, and Sirius box. Everything is screwed down and have cable ties securing cables. This area is not visible. This tray is above spare tire and below a fiberglass panel.
Tweeter on door. There is also a flush mount which I may change to:
USB jack in lower storage bin:

Here is sub/enclosure with the seat unbolted from floor and leaned back:

Everything sounds great and I'm looking forward to it breaking-in a bit. I'm very impressed with the MB Quart amp. It has very clean sound and does not get very hot (which is good news given that where I have it has no ventilation).
The component set sounds amazing though I'm starting to wish I was feeding them more than 80 watts RMS. Mid-bass is very rich and deep...the highs are fantastic and not too harsh. The set sounds so clean and natural. I'm hearing stuff in music that I have not heard in my home system.
The Kicker sub/enclosure really has surprised me. It sounds amazing for what it is. I'm really blown away that it can produce so much bass from such a small package. It really works in well with the PPI component set as well. The bass is very tight and not sloppy at all. I'm surprised at the thump this sub can produce as well. This sub is known to need about a 2 week break-in period so I'm looking very forward to it getting even better. I set the gain on amp for the 2 channels I have bridged to run at 200 watts RMS at 80% volume. Sub is not overpowering the components even at high volume. It is obviously not window shaking bass but it is only an 8" sub in a tiny enclosure. That being said it is very impressive how much bass they managed to get out of this. It is more of a sound quality sub than a loud sub. My components get very low and sound great but when I turn off sub now it is amazing how much low end I was missing.
That is it for now. Thanks to everyone that has given me advice here. I would have gone a much different direction if I had not had all the good advice that I got here.
