What amp(s) would run 18 Fi BTLs to the max? Trying to keep it around $1000 give or take. I was looking at the Hifonics XXV Goliath, but I am still not sure. What do you think?

whats the box look like.

More importantly, what does your electrical consist of to run this beast of an amp?

I got an Opti 50c for 300.00 shipped. Gave me a 143 off stock electrical.

Sorry, not doin it. Cant afford all the electric. 2 more alts and 3 more batteries for what I want...damnit

i had a goliath on a set of bl's....

i hated that damn goliath... nothing but problems.... underated... just a bad year of my life!!

check out some saz 3000d's nightshade.. you can find them in your price range... over 3000 watts and no headache.... dont think about it do it.

So are you considering a smaller or lesser expensive set up?

Go with one of the Sundown aps from DBR. They've got good prices and may have something that wont kill your electrical.

Class Ds have similar efficiency, at least close enough to not matter (we are talking with 10% or so).

Bottom line is, the more power the amp, the more power your electrical needs to supply, regaurdless of amplifier type or make.

And what is to the max? Until they blow? Nobody can answer this for you without enclosure details.... A BTL could reach full output with far less power than you are talking in the right box.

Additionally, there is no such thing as underpowering these (or any) subs. If you have 2 BTL 18s and only 4-500 watts each, they will still be louder than just about anything else.... If you have a few thousand watts each they will be louder, of couse, but this isn't mandatory. Additionally, once you get to a point where thermal and mechanical compression sets in (not much over 1000 watts) your returns on adding power exponentially decrease.... To the point of equalibrium at thermal failure....

Back on! New alt, new batteries. Its down between Goliath, Stetsom 4k2, Memphis, or Atomic.

I've used some of the recent hifonics amps and they are junk. I wouldn't even wast my time with them.

SUNDOWN SAZ-3000D FOR THE WIN!

LOL don't think about it, do it!!!!!!!

seriously, the SAZ-3000D will surely be worth the money and not a waste of your time like some of these other brands.
