    Good clean power!

    I picked up this amp to power four Rockford Fosgate 6.5” component speakers. I was previously using a Kicker amp on them but the amp was getting way too hot. This little SFB-200.4 is a powerhouse. Not only does it stay cool but it increased the sound quality of my speakers substantially. It’s night and day difference! I’m seriously impressed with Sundown products.
