Fi Btl 18's


Recommended Posts

I have decided if I am going FI that I need to go BtL over BL, and need some help on the RMS figures. I know Steve runs 4kRMS per 18 and does very well, but how do these subs respond to only 2krms each? I have heard they can eat up 10krms each and keep going. Do you need the full options to run higher power? Will the differance of 2krms to each versus 3krms or 4krms to each be that massive? This is a Daily driver vehicle. I am planning on running Hifonics amps. Thanks for any advice. :blink:

They wouldn't handle 10k. I dunno where you heard that. Steve gives his around 4-5k, but it's a real clean signal, backed up by plenty of batteries/alts. They're rated at 2k watts, they will definitely respond to that.

A couple links to some box builds:

Tahoe Box 1, Tahoe Box 2, Nissan Titan, VW GTI,

Mini-Bump, Hummer H2, Ford F-150

My own car builds (current setup --- under construction):

Overall Thread, Kickpods, Dash, Back Doors

Subwoofer Wall

10k rms is a lie, I'd say 5k rms would be just on the border of pushing it & thats in a perfect box, clean power FULLY loaded.

Get the 2500 one, you'll be able to get a cleaner 2000 watts with that. (Meaning you can push the amp less hard, therefore less distortion)

Goliath it is! I can get them for around 950-1k$ each and might run 4 btl18's and 2 goliath's, then again might try 2 btl18's first and add 2 more later.
