Great Amp

Clinton, Crutchfield
6 December 2015
  • Summary: After changing out the speakers I didn't feel like there was that much of a change. Added this amp, it made the speakers come alive. It was easy to install and fit neatly behind my dash.
  • Pros: Small, easy to install. Gets louder then I would ever want to listen.
  • Cons: None

Alpine KTP-445A power pack

PaulG, Crutchfield
30 November 2015
  • Summary: This amp power pack made some serious sound attached to my Alpine CD on my Harley Davidson. The 4 5.25 speakers never sounded so good until now. Highly recommended source of small clean power.
  • Pros: Very compact. Clean sound. Good value.
  • Cons: None

Powerful little punch

Martin, Crutchfield
23 November 2015
  • Summary: Great for people who need an amp in a very small space (does not require a separate wire kit, it piggy backs on the receiver). It even fits behind the dash in most cases. It is also a great idea if you are adding new speakers in the door along with a new receiver and want more than what the receiver...
  • Pros: very compact, better power than a new receiver alone
  • Cons: if you like bass you will have to add a separate sub (i recommend one that is compact, can fit under the seat and has a built in amp such as infinity BassLink SM)

Nick C, Crutchfield
18 November 2015
  • Summary: I purchased this product along with 6 Kicker speakers for my 2015 RAM 1500. I had this amplifier installed professionally and it was mounted inside the glove box of the truck so that I could adjust the gain controls if needed.
  • Pros: Small size, Huge sound. Price. Compatibility with factory HU. Gain controls.
  • Cons: None, time to buy this Power Pack.

Easy Peasy!

JScott, Crutchfield
11 November 2015
  • Summary: Very pleased with this amp matched up with an Alpine CDE-SXM145BT installed in a 2012 Kia Soul. This amp tucked perfectly into the dash once the factory unit was removed. Didn't even need to drill any mounting holes! It gave my son a great lesson on why power is a good thing.

Nice, small power

MattO, Crutchfield
9 November 2015
  • Summary: I installed this in a 2008 Tundra. I removed the panel to which the glove box is attached and put this on the back side of it. It is out of sight but I can adjust the gain easily by looking under the glove box. I'm sure that description is clear as mud. It made the stock speakers really come alive.

Best Decision ever

sarge, Crutchfield
14 October 2015
  • Summary: Quite possibly the best decision i have ever made in car stereo installation is to get one of these power packs installed with an Alpine head unit!! My Infinity Speakers are rocking off the charts, the RMS wattage per channel definitely helps to offset the giant bass I am producing with my amp and...
  • Pros: Amazingly easy to install, easy to hide, fits perfectly behind dash
  • Cons: None... Even converting my standard fuse from 10amp to 15amp was extremely easy, these should be a bundle option with every alpine stereo sold!!
