    Great sound! Loud!
    I love my PRV 8’s speakers and love loud music for the price of $40 you can’t beat that deal for the sound. These bad boys are loud and I have two 8’s in both front doors and two tweets. When I open my doors and play my music you can hear me from a far distance. I will be upgrading to the Neodymium which are the best ones you can get they’re even louder and take less watts to power them. I love loud music and will not stop until I’m trying to get out of my car because it’s too loud. I’m currently getting a better powerful amp hooked up to my mid’s and putting a battery in the trunk so that I can get the max possible to push my music to its full potential
