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.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003eOur favorite feature we introduced of the Krypton series is the \u003cstrong\u003ebass remote that has a clipping indicator\u003c\/strong\u003e. 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).\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"text-align: center;\"\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003e\u003cem\u003e\u003cspan style=\"background-color: rgb(255, 255, 0);\"\u003eWe guarantee that this series of amplifiers will not only meet their Dyno Certified power but exceed their rated power.\u003c\/span\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003eAnother feature we love about this is the bass equalizer. Most amps have this feature however not all bass EQ are created equal. Some bass EQ's will just clip your subs to death. Our bass EQ circuitry will boost the proper frequencies in a way that sounds good and is safe for your subs. In addition you can always use the clip indicator on the bass remote to make sure you are not sending a clipped signal to your subs. Our amplifier is meant to give you as much clean power to your subs as possible. Our voltage display allows you to make sure you are getting the proper voltage to your amp and our clip indicator on the remote will make sure you always send clean power to your subs. In addition we also guarantee the amplifier will be giving over the rated Dyno Certified so you can confidently match our amplifier with high-end subs and know what to expect!\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003e\u003cstrong\u003eWhat about sound quality and efficiency though?\u003cbr\u003e\u003c\/strong\u003eWell glad you asked. This amplifier is engineered so well that it has an extremely low signal to noise ratio which just means the sound will be super clean even at high volume levels. It also has a good efficiency rating so you don't have to draw too much power from your battery. One other thing that is important is that we engineered this to have a high common mode rejection rating (CMRR). This means that the amp has the capability to block out engine noise signals. By rejecting unwanted noises the end result is the cleanest sound quality.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: rgb(31, 73, 125);\"\u003eOnce again, Rockville has stepped up its game with the all new Krypton series.
