wen I got it found out it was a bit loud on the highway so I decided to sound detained it took the entire interior apart and realized it has close to no sound detaining in it except the fire wall, and came to realize that Dynamat would be too expensive for the whole car. I got something named peel and seal not made for the purpose I used it for but works great, soon I'm planning to use 3M underbody sound detaining spray on the underbody and it also fits my budget. I also have a sub installed its a 10" but it's a JL Audio but works really great because it's really expensive $300 without the box real compact and leaves plenty of space in the trunk for my Corolla. Also led all the way in the interior and trunk but done right and not just a sloppy teenager job which I am a teenager but I'm going to a school for automotive technician so I know how to do crap. The regular lights are already led so I also replaced fog lights to LEDs which looks awesome.
