Description: 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).

  • Best budget amp that I've ever bought
When I bought this I had decided to switch my system from three 12's to one 18 and had the seriously stepped my power up. I jumped from running 600 watts at 2 ohms to 1100 Watts at 2 ohms and it made you feel like somebody was grabbing the sides of your head and squeezing when you were sitting in the cab ... show more

  • Good customer service
It's a decent amp iv owned about 3 of them in the past 5 yrs or so they average about 2 yrs for me ... the last 1 I got was faulty and broke almost instantly within a wk or so .. so they shipped me a new one and told me to send broken 1 back .. excellent customer service 👏 hopefully this 1 holds up like my previous purchases ... show more

  • I'm not sure about it ...ok updated
At first I was like ok this seems nice got some new features on this one I've never had like the clipping light but I thought I was upgrading from a boss 3000 watt amp and right now I'm not impressed but I'm still upgrading my power system my alternator isn't enough to push this amp like it would need for the full power so I have one coming and I'll update this after the install right now it's about the same as my boss so it's gotta be power issues on my end.... I'll let y'all know in about 2 weeks when it arrives well I upgraded a few things and this amp is amazing way more power than I had this was definitely a good buy for me my subs are.gitting harder than ever!!!!
