    These speakers can handle 450w each from the amplifier. You can use less power but they will perform better with full power.

    If you are talking about our Sound Bar it is wired to use 1 amplifier. I suggest the TPT-1400 1 ohm. If you are running a custom sound bar with 4x 8MB450-4 V2 you will need more power than the TPT-800.4. I suggest again the TPT-1400 1 ohm for the whole system or for just the 8MB450-4 v2 and a TPT-400.2 for your tweeters if you want to run them separate.

    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
