Need help deciding

I’ve been lurking for a while coming up with options for a subwoofer and amp to go along with my factory Car-Play head unit. Initially I was looking at installing a mono-block amp and a single 10” sub. Then I started watching YouTube videos and saw a video by Provo Beast. In his video he uses a 5 channel Kenwood amp that processes high level signals so a signal processor like an LCI2 wouldn’t be needed. In Provo Beast’s setup he uses a Skar Audio 10” sub box but uses a 10” Kicker Comp RT because it’s 2 ohm stable. Total cost for that setup would be around $700.
I also saw TrailGrid Pro has a sale on an Alpine Powered 8” sub with a small 4 channel amp for the door and dash speakers for $650.
Not looking to spend over $1000 and I don’t need a ton of bass. Would you guys have better suggestions of what you would recommend? Is the Alpine setup decent?
