People seem to be drawn to the Q because they advertise it as their Sound Quality line sub that gets very loud. Thats what drew me to the sub when I bought it. I was in the exact same place the OP is in. I wanted to do a nice loud system since I could finally afford to do it the right way now that I'm older. Had a vision of what I "thought" I should do and basically did it. I bought a Sundown 1500, FI Q 15, Alpine 4 channel, Rockford Components for the front and ran my Alpine Type R 5x7 coaxials in the rear all in stock locations. I loved the setup and everyone that heard it was blown away as I was for a couple years. Now that I have alittle more knowledge and gradually went for more and more I realize some things I could have done better. Even now I am kinda starting over for this new truck I have and will likely be going back to a simple, loud and clear sounding setup. Staging and how clean something sounds to me is two different things. Yes I would like a properly staged system but I have also heard a few SQ vehicles with perfect staging that sounded very dull to me and some I have heard sound incredible. My opinion and this is only my opinion, some would disagree and say that it would sound like ass and Im stupid...idk But I would do a good headunit that offers a nice EQ and hi / low crossovers. A nice 1200-2000 watt amp for the sub. (the Q is fine and will get loud and clean. Mine did 147db in my single cab) A good 4 channel amp, IA, Rockford, JL or Alpine, just a few examples. The new Crescendo line may be fine but idk. A good set of components for the front, and a decent set of coaxials for the rear fill if you want to. It wont hurt if you have a suv and have rear seat passengers alot. If your by yourself more than not then just turn the gain way down on the rears or fade more to the front. Take the whole family on a trip and your not blasting the fronts while you listen to your kids BS teenie bopper music because you only have front speakers. Make sure you sound deaden really well and if the installation is done right it will sound great and last as long as you want it too. Then after a year and the bass bug hits you can go really big and in the meanwhile you can read and learn what you like and dislike about your setup and improve from there. Just my 2 cents
