Review on 🔊 Enhance Your Car Audio Experience with the Alpine KTA-450 4-Channel Power Pack Amplifier by Joshua Gaines

According to the installer, the installation of the device was quick and easy. That was pretty much the only positive I have as the amp has been acting for the last 2 months. Sometimes the main unit would turn on, but there were no front or rear speakers (only the subwoofers were enabled). I would have to turn the car off a few times for the amp to "wake up" and the speakers to start working. Now I'm facing an issue where volume spikes occur on all sources like bluetooth, usb and radio. They are random and occur when the vehicle is moving at high speed or is in a parking lot. So annoying that I've already ordered a replacement.
