Alpine DPP Power Pack Amplifiers

Dynamic Peak Power (DPP) Technology

The KTA-450 features Alpine’s exclusive DPP technology which intelligently adjusts the gain to automatically adapt to musical needs. DPP prevents the amplifier from clipping music signals by supplying up to double the power to support rhythmic instruments that provide snappy sounds (like a snare drum, trumpet, or high-hat cymbals). During these dynamic musical passages, DPP instantly delivers bursts of power to rise to the peak demands of the music. The DPP technology boosts the KTA-450’s performance to 400 watts DPP, essentially doubling the amplifier’s power without increasing its size. Other Power Pack Amplifiers with the DPP technology are the KTA-30FW and KTA-30MW.

Why wasn’t this type of amplifier developed years ago?

This is a fantastic little amplifier, but it’s not flawless. On the plus side, this thing really does deliver amazing output for its size, and the convenience of strapping it on to the back of a mechanical-less Alpine head unit is ingenious. The only real downside is that you have to adjust the gains before you mount the radio, because once it is strapped to your face plate and screwed to the mounting brackets, the gains are no longer accessible.

Great product

The small amp that fits behind the Alpine double din radio mounts right to the back of the radio for easy installation.

Far Exceeded My Expectations

I wanted a small to boost my system with smaller foot print amplifier, that I didn't have to run wires into my doors for the speakers. After my research I came across this amp you what sold me was the (DDP) DYNAMIC PEAK POWER. Let me tell you this amp gets loud and stays crystal clear. I have the KTA-450 hooked up to JL Audio C2-690tx's. this set up is phenomenal. If you're thinking about this amp DOIT you wont be disappointed much louder than I expected and will pierce your ears if you max out the highs lol.
