Hello, well after a little research and all, I finally decided on an upgrade and had it installed yesterday. This is what I went with:

Wiring: Rockford 8 Guage - http://www.rockfordfosgate.com/ezcom...e.asp?key=1564

Cap: Lightning Audio B10-03 - http://www.lightningaudio.com/2004/p...asp?prodID=151

Amp: JBL 72.2 - http://www.jbl.com/car/products/prod...er=GTS&cat=AMP

Enclosure: Q-Logic Ported hatchback Enclosure - http://www.qlogic.ws/2003/products/q...productID=7193

Sub: Rockford Fosgate 12" Series 2 - http://www.rockfordfosgate.com/produ...h%20Subwoofers

Any opinions? It just fills out the whole system. I already had an upgraded 200 Watt factory Monsoon system, 8 speakers, MP3 player and all but just wanted to add some bass, and this has really added it.

I just have a few questions though. My amp has been wired up for bridged mono operation, so does that mean the mono/stereo setting should be set on mono. When I brought it home, it was on stereo, but I changed it. I also have the X-Over mode switch set to "LP." There are also other settings on the amp like "bass boost," "X-Over," and "Input Level" (all turn switches with a screwdriver). I guess these need to be tweaked since while listening on my first drive, it seems as the amp is not really cutting out, but it will pump out a ton of bass, then not at much, then back up again and so on (fluctuates a lot). I played with the settings a little and it seems to be pretty stable now. But I want to know what order should I set these settings and all to get the maximum performance. If you could help me out, it would be greatly appreciated.

Thank you!
