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

The following review is for KTA-450, which is a part of the bundle you are viewing.

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 following review is for KTA-450, which is a part of the bundle you are viewing.

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

The following review is for KTA-450, which is a part of the bundle you are viewing.

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.

Perfect compact screen.

The following review is for KTA-450, which is a part of the bundle you are viewing.

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.
