Full-Range Car Amplifier
If you are using an Alpine iLX-W650 or iLX-W407 multimedia receiver and are looking for the perfect full-range car amplifier to power up your vehicle's audio system, then the Alpine KTA-450 may be what you are looking for.

Although it can work with other receivers, the Alpine KTA-450 is designed to be mounted on the back of the mentioned Alpine receivers above with the help of a PowerStack bracket. Using Alpine's Dynamic Peak Power technology, the amplifier can automatically adjust its gain to produce a more powerful audio output that is perfect for your musical needs.
