Looking to start buying the pieces for my next build and im fairly sure im going to be using a bc2000 to power it but as far as drivers im pretty split between a few options. I want to be able to get really loud at around the 30-33hz area and really loud period but no a complete loss of musical ability. Going to be a daily driver build. Mainly been looking at either 2 15" ssa icons, dc level 4s, fi bl's or 4 sa-12s. Im leaning toward the sa-12s right now. Any advice would be appreciated.

I just received two 15" SSA icons today and will be running them on a crescendo bc2000d in my Dakota. I'm waiting for box design and I'll start a build log and tell u how I like them. The build quality on them looks top notch and mark and Aaron are awesome. Customer service is second to none! SSA FTW

There are more important factors that go into "being loud" than subs. Get your install design handled first.
