Lost count really, i have gone through many systems looking for what i wanted, spent over 3 grand, mainly the amps and subs cost the most and a lot of man hours. You need to make a custom stealth shelf, not hard to do, just blend it in and cover the lot with speaker cloth matching the interior colour of your car. Still working on plans on next audio setup for when i get my hands on a glanza v and will then sell all of my subs.
