The Sirius Upgrade works great and turned out pretty neat and out of the way. The Subwoofer and Amp story will be on-going since I work for a place that sells these pkgs, I have already tried 3 different set-ups and will be trying 2 more next week, once more stock comes in. The Visonic is a real inexpensive unit Under $100.00 that sounds really good as long as you do not push it too hard. The Rockford Fosgate Sounds about the same but takes even less abuse, and it cost more? Just goes to show you that you do not need to spend a lot. The best was the SoundStorm so far which was under 200.00 for everything. The sub takes up very little room in the back and kinda looks good sitting there anyway. It can be removed in about 30 seconds if need be. The amp fits easily under the seat. Here are the pics. I can not post pics of the SoundStorm until I re-install it next week.
