Packs a very small punch
Tom Palmer on 12/09/2016 4 star rating

The KTP-445A is a very easily installed amplifier for use with 2005 and newer Alpine Headunits. It is a very simple install: 1. unplug the head unit 2. plug in the KTP-445A(assuming the alpine is already installed) 3. reinstall the head unit That easy. If you dont have an Alpine Headunit, get the KTP-445U, which is universal, and will require some splicing/wiring skills. I have had this installed for about a month now. Here is what I think: The PROS: 1. Ease of installation, seriously, find a small, well ventilated (it gets hot) place to stash it within about 3-4 feet of the headunit. I zip tied it to a wire bundle under the dash 2. Very compact amp, see above. 3. Specs are impressive (for the size), especially compared to some of the competitors. Clear, un-distorted audio for those who don't need to win any competitions. The CONS: 1. For the price, I would expect preamp output compatibility. This only uses your speaker level inputs. There are two plugs, one input (power/ground/speaker/etc), and one output (speaker). It would have been easy to make the speaker level inputs a separate plug and add low level inputs. 2. Due to the above, the volume doesn't get much louder then just the headunit, but it is clearer and less distorted at those higher levels. Overall, 4 out of 5. This is due to how compact the amp is and the ease of install. I probably wouldn't purchase it again, but a day turning wrenches is my favorite kind of day.

great for small cars

If you don't have much space or don't want huge amp's cluttering up your boot this is perfect.

  • Question: 10 May 2018
    Hi there,

    Do you stock the Apline KTP-445U (universal) model or know where I could purchase one? Looking for the separate gain controls without Apline head.

    Many Thanks,
    Alex

    Answer: 
    you would be better off with the GMD1004 as its cheaper, and will do the same job

    hi there cant decide which head unit to buy for good sound quality looking at the alpine CDE-178BT and the CDA-137BTI which says is the flagship model but the only 1 with DAB is the CDE-196 DAB?

    Answer: 
    Hi,

    Thanks for your question, The CDE-196DAB is the only DAB unit, all of those mentioned are great for sound, however if it is sound & quality, there is the Pioneer DEH80PRS which has 24 bit DAC processor & binary EQ

    Hi, please could you let me know if you still sell Alpine KTP-445U as I can't find it on your website.
    Regards
    Dave

    Answer: 
    Hi,

    Thanks for your question, on the website there is the KTP-445 (only 2 in stock) not a KTP-445U, If you give the online sales team a call on 0330 1234 021, they may be able to help you.
