EASY INSTALL
Sonic provides all the right cables for your install...very easy....amp works great with no issues over the last month or so that I have owned it. Its hooked to a 149BT...sound quality is very good. one note it is bigger than it looks in all the pictures so make sure you look at the detailed measurements. It looks like a extra large laptop charger.

very good amp, easy install
If you own an alpine head unit this is the amp for you. If you don't need a huge amount of power this will work, small enough to place in the dash, its just plug and play, and it doesn't pick up alt whine which is why I'm using it

Great
Product arrived on time. Great amp, compact, clean Alpine power. Installed in the dash of a 2013 Jeep Wrangler with no problems.

Great Product
Quick easy installation. Just plug it in between your Alpine radio and the wiring harness that came with the radio and within minutes you have louder and in my case clearer sounding music.

Alpine KTP-445A
This is a great product, I love it and it was very easy install. Just plug and play very easy. My speakers sound so much better and I couldn't be happier. I would absolutely buy another and you should too.

Great sound
This was a great addition to my car, I was on the fence about getting it but now that I have it I wish I would have gotten it sooner. It is very easy to install the hardest part was finding a nice location to mount the unit. It did wonders for the sound quality in the car. I am very happy and would recommend this to everyone.
