Almost complete audio system upgrade
So I'm looking to upgrade basically all of the major audio components in my 2007 Saab 9-3 to get a really good setup going. These are my subs: CompVR aluminized Sub Boxes | KICKER here is the amp I have for them: Rockford Fosgate® - R1000-1D. Now, I want to replace the front door speakers, the stereo and the dash speakers. If at all possible I'd also like to install another amp if that's viable. Also considering the rear speakers but not sure. Can anyone offer me good replacements for these? I'm looking at spending about $400 more (I got the first two on the cheap and I'm assuming I can do that for the rest).
I've heard the front door speakers and the stereo can be a real hassle, are there products that get around the major problems? I'm looking to do little to no modding of the car itself, if possible. Finally, any tips or suggestions? Thanks for any input.
