Rockville Car Audio combines powerful bass, crystal-clear sound, and durable designs for an unbeatable car audio experience. Rockville Home Audio offers rich, immersive sound and sleek designs, perfect for enhancing your home entertainment experience. The Krypton series of amplifiers by Rockville are engineered to have the best reliability and features. Whether you are a car audio competitor or just like to enjoy loud music. We engineered and designed these amps from the ground up to give you great sound quality and great features. You will notice the cool battery voltage display meter which looks great but also serves as a tool for you to know if your battery voltage is dropping which would affect your systems performance. We designed the amps to be able to last for many years even if you are playing them at max volume before clipping for extended periods of time. Our favorite feature we introduced of the Krypton series is the bass remote that has a clipping indicator. This allows you to set the amp to max output before clipping on any song. This will protect your subs while you maximize SPL. What is nice about this is that you can set the gain level to max before clipping on any given song in real time! If you use a DD-1 or another tool, you are setting the gain on one song but the next song might have more headroom or might clip depending on the levels it was recorded at (this is referred to as crest factor in the engineering world).

  • Excellent amp for your buck
I've got 1600 watt mono amp pushing 2 12 inch mtx in a sealed box in the back of a 2001 chevy surburban. This amp pushes then like their is no tomorrow. For what's its worth their is a lot of dead space in the back and this amp gives the subs a good beating . Love the black finish on amp and the bass know is sweat. It's perfect when songs are clipping I can dial it down a notch best amp yet under 200. ... show more

  • Great amp
My favorite amp. Been using on 2 12inch subs for 1 year now and did not overheat. Also battery gage and bass knob comes in handy for songs with different bass levels

  • Amp is amazing definitely recommend!
At first when I was looking for a good amp to use on my dual 10” star subs I wasn’t sure what would be a good amp so I read some other reviews on this amp and I got mixed reviews some say it’s good and some say it’s not. Well I’ll tell you what based off my review this amp is amazing. It is fully adjustable it is easy to setup really nice quality sounds amazing. The bass knob is smooth to turn and it has light indicators on it which is nice, this amp has my car shaking with my dual 10” star subs. I highly recommend this amp! But overall it’s personal preference. ... show more
