The amp fluctuates in price on Amazon. I was able to get it for ~$110 shipped.

Note that you still have to pull out the headunit to install the amp.

I highly recommend the Kicker tweeters. I installed them on my '19 STI and it made a huge difference in sound quality. They were super easy to install.
