I have an 06 f150 STx and I want to put my system in it but I want to use my stock head unit is it posable to do tht and my truck has the vynil floors and is there away to run my amp power wire under it. If all this possable could you walk me through the installation process

 

even with the plastic floor you should still have the normal sill panels where the door meets the floor correct?

 

x2. There should be floor step panels between the door frame and the floor. It pretty much just pops up, while the kick panel pops back. Also if you want to connect to a stock headunit, you'll need to use a line output converter. A suggestion with this is to connect your LOC at the back of the headunit with BOTH left and right RCAs run at the same time as your remote wire, IN CASE you ever decide to upgrade your HU then it's one less thing you need to deal with to get the full audio effects of an aftermarket HU.

If you need a walk through of the install process of the amp, then you might want to resource the installation. There are multiple options in finding a suitable location to mount your amp, either under the front seats, under the rear seats, or on a back wall (which is different if it's a regular cab vs a super cab or super crew). First, see where you want your amp located. People have their everywhere and it's strictly preference. I have mine under the front passenger seat because it's convenient, it fits, and never gets eyes laid on it. Some people will argue that spot because my truck has floor vents. I would highly suggest checking out photos of installs. You can thumb through peoples' images, a lot of users have pictures of their installs from where the wire was run to how they even made their boxes.
