Hello.
 
	New member, my first post.
 
	Looking to replace my current system with something better. I currently have 2 x 12 L7s, 1 x kx1600.1 and l2ci. The car is bmw m4, 2018.
 
	I've been looking at getting 2 x 12" icons. Need suggestions on the type of box and amp that would work best. I'm looking for sound quality but also loudness. I don't have much trunk space.
 
	Right now, i'm using a sealed box up to kicker specifications with polyfill. Current system is loud and works well but lacks quality. I would prefer a sealed box.
 
	Kicker subs only play low tones and need something that plays slightly higher (100hz-250hz or so).  The stock system sounds really nice on anything higher than 200-250hz. Are icons right subs for this?
 
	I've been also looking into jl audio w7s but do not like the price. 
 
	Thanks in advance.
