Better than stock.... we all know how lackluster the factory system is, just have to be sure to upgrade it the right way.
We develop kits with the Kicker speakers, they are good, but just depends on the customer. They tend to be a little too efficient/aggressive/edgy at times for our older client base. For the younger crowd, those who want more volume, it's great.
Not a fan of them grounding on the rear wall in these trucks, we have stated for many years to run a dedicated ground to help stabilize the electronics and ensure the longevity of the products (customers' investment) is preserved. These trucks are glued together and the cab will show 5+ohms of resistance, aftermarket electronics will not tolerate that for long.
The minimal sound treatment in the quote leaves the door open for buzzes/rattles. If that does not bother you, then one roll is ok. We tend to go a little more in-depth and send 6 double sheets minimum with any plug-and-play kit.
Overall, it's a complete system and you have to decide if that is the level of performance you are looking for. If you are willing to explore additional options or possibly install it yourself, I know someone who offers a more composed package for your truck
