Product Reviews For Alpine KTP-445U

  • These are superb little amps. Very small but pack some power. Great for an upgrade from stock radio to give better sound and more power.


  • Great little unit, fits nicely under the dash and provides a great punch to my music. This is no tube amp, but for the price, you get a decent quality sound. Most people wont need much more than this little unit.


  • considering that it is named Power Pack, this amp really deliver powerful sound as it is packed in a compact chassis, and even with its size it is still impressive and has exceeded my expectations

  • Installation was smooth, and it was also very easy to fit in due to its small size. Can power up my whole system and it surely sounded great.

  • Got this amp for my Subaru hatchback. Changed out the stock speakers with Alpine Type-Rs and Let me tell you, this little amp is nothing short of amazing. Packs a whole lot of sound in this tiny package. Alpine never disappoints with their killer products.


  • Tiny but powerful! It was an easy install, and its really pushing my JL Audio speakers cleanly with nice sound.
