Looking for a new system

[ea5522 0]

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.

Welcome to the forums!  You are on the wrong track however.  Subwoofers are not designed to produce higher frequencies.  The bands you are looking for are actually midbass frequencies.  These are best produced by the midwoofers in your doors.  I'm afraid you could trade subs until the world's end and not be satisfied.
