• Total RMS Power: 200 watts

The KTA-450 can mount behind select Alpine 2-DIN mech-less head units, like the iLX-W650, using the included bracket. The KTA-450’s recessed harness receptacle allows the wiring to fold between it and the head unit so both products fit in a standard 2-DIN space. This PowerStack design is a 2019 CES Innovation Awards winner and makes the duo one of the most powerful 2-DIN radios available.
The KTA-450 features Alpine’s exclusive Dynamic Peak Power (DPP). DPP intelligently adjusts the gain to adapt to musical needs. DPP prevents the KTA-450 from clipping by supplying up to double the power for sudden, dynamic sounds. DPP ensures music sounds the way it should at high volumes and boosts the KTA-450 to 400 watts DPP, doubling its power without increasing its size.

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.

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.

Absolutely amazing sound quality ????
I am blown away by this amp, which is installed in pair with the Alpine ilx-650 headunit. So nice that it fits behind the radio in dash, wiring was a Breeze. Installed in a 2007.5 silverado 1500. Absolutely blown away.

Perfect compact screen.
Wanted to put newer technology in my kids car so he had a back up camera, Bluetooth/handsfree, and a screen for map purposes. It performed perfect like every Alpine product I’ve had and was more than pleased with results and use. We built a system around it and loved the functionality of it all. Would highly recommend.
