I was fortunate enough to win this package from SGS last year during their giveaways. I immediately did all 4 doors on my F-150. I was very skeptical of this making a difference and if you asked me prior to my install I would have said theres no way it would make a noticeable difference. Well, I will say I was wrong about everything. This is a very well designed package and makes a tremendous difference in the way your music sounds as well as the amount of road noise you hear.
The mid bass from my speakers was the biggest difference, I believe this is from the door block off plates, this would be the best bang for the buck if anyone was looking to do a cheap upgrade. I did everything at once so its hard to tell but all I can say is I was blown away on how much better the stereo sounded. Keep in mind I am running factory power on some lower end powerbass drop in speakers. I do plan to add a Kicker Key in the near future and I am sure this will compliment the sound package that much more.
During my first drive I 100% could tell the cab was quieter. Once I saw how much of a difference this made I immediately applied Blackhole mat to the rear wall which made a slight difference as well. The kit comes with plenty of material, even after doing my doors and rear wall I still have well over half a box of blackhole mat left.
The crew at SGS has some awesome customer service, I reached out several times with questions and they were always quick to respond. For anyone with a 21+ F-150 they have detailed videos on how to take apart your truck and install everything. These videos are applicable to anything sound deadening related or even installing custom speakers in your truck. I watched these videos several times and would of been skeptical of doing the install myself without them.
If anyone is contemplating this ki.........t it is pricey but I can guarantee you will see a noticeable improvement.
