AlpineKTP-445A KTP-445 Head Unit in Line Power Amplifier, Black

Alpine is the best , plug and play amp so simple to install with alpine head units. Save the trip and money to the car audio shop and hear what you've been missing in your music. Get loud live clear music with this amp. Aftermarket speakers and bam concert in your ride. You don't have to run new lines of wires buy fuses or find space in your trunk to install. Small and compact fits easily behind the dash and gets slightly warm to the touch but no near hot when used heavily. 45 x 4 watts RMS give your speakers some power to perform.

I’ll put it to the test tomorrow on the road but in the garage it makes the sound more crisp and louder for sure. ThanksUpdate: gives added clarity and volume so that’s good since it’s on a 2005 Harley-Davidson Electra Glide lol

As far as ease of installation, there's not much more simple (with Alpine deck). Same goes for finding a good place behind the dash to safely tuck/mount. Power wise,...well, obviously 45 watts per channel isn't going to blow anyone away but it definitely livens up a stock system and I'm sure has a bit more potential when paired up with an all around stock speaker upgrade with matching alpine front to back left to right replacement speaker upgrades.

Only fits alpine head units

I was pretty excited to try this out, hooked it up with my alpine head unit. I recommend JL audio speakers with this btw, clear quality sound. Worth the money in my opinion, Sautered and heat shrinked all the wires for a clean connection.
