    Q What amp is best for the 225 Watts RMS of each speaker ? answer now
    Asked by admin on April 3, 2019 3:00 pm
    Answered by the admin Any amp that provides up to 225 watts RMS at 8 ohms will work, We do have a 4ohms version of this model - 8MB450v2-4 Ohms but beyond that it depends on how many you have in your application! If you have one pair of of this model, for a car audio application you can use the A4MH PRO, you can bridged 2 channel and wire the speakers in parallel to it and the other 2 channel you can add 1x TW350Ti per channel

    This is a very nice speaker, lots of guys use them in my area and I have seen them in all kind of set Up’s, for it to be what’s considered there bottom of there line, it sounds better than other brands tops. Definitely need a good amp to run it, factory don’t cut it. I use it for a 01 suburban replacement and I had to by pass the factory amp with a new one.

    I replaced the woofers in my Behringer B802D 8″ powered speakers with this PRV 8MB450 I needed to do a screw hole modification in order for it to line up with the holes in the cabinets, but after I got it installed, all I can say is WOW!!!! these speaker’s have KICK and there much more sensitive then the original Behringer speakers. They need very little volume to sound loud and clear, even at low volume there Awesome!!

  3. Kevin ONeil

    I replaced my Crate Taxi 30 amp stock speakers with these and it made a huge improvement in sound quality…also changed the stock speakers of my Crate Limo 50 amps with PRV 4 ohm 10 in speakers…the results are amazing. I would strongly recommend PRV speakers to all seeking a fantastic upgrade in their sound….
