Greetings!

I'm a long time lurker but just joined as I became a new Subaru owner back in 2019. I'm looking to upgrade from the terrible stock sound system in my 2019 wrx and wanted to get some input on a good system for it of course without the wallet taking a huge hit. I listen to a lot of electronic music and Hip Hop (classics) so I want to make sure the system can handle it while maintaining optimum audio clarity. On a secondary note but in the same vein of this post would anyone also have suggestions for stabilizing the windows so I dont get the windows rattle noise when the bass hits? Is it just sound deadening material in the doors that will alleviate this?

Your help is greatly appreciated!
