Received Open Box Item
This review is for the type of item I received and not the item itself. I purchased this item with the understanding that it was new, but it was open box. I have attached what I received vs. what a new one should look like. It is really unacceptable to send open items when a customer purchases a new one.

Amazing
I added this and was IMMEDIATELY impressed with the sound. This made the music come alive and have depth that my deck couldn’t provide. And it’s tucked in the dash. It’s super easy to install and is 100% worth it. The watts per channel is more than adequate
