Fu 750's just went up $20..

[Hertz Mafia]

i modeled darths 15" 750 sub with his box and same power it's have 1/2db more sensitivity at 40 hz, 2 db more at 50hz and lots more cone area so i'm sure he'll be 5db louder than me but thats a 15 with over 50% cf bigger box so not bad if i end up around 135.. also weird thing is mms is lower on fu than my pioneer..

Dude u can model shlt on a computer all you want... once u put it in a car all that goes right out the window. Get it hooked up and there only one way to find out. I wish you luck because your going to need it

that FU will have the time of its life laughing at your amp. It was already gonna laugh at it at 1 ohm but at two ohms its not even funny anymore.

whatever your amp actually does at 2 ohm - like 10% from that it'll be close to that (like 3ohm)., mine at 2 ohm will get about 4.5-5ohm so about 450 rms.. saw a belva 3k test at 928 @ 2 ohm so yours maybe 400-550 actual but never know..

Idk how many times I have to tell you I have a dual 2 ohm and I'm running it at 1.

u still not getting it.. sub is at 1 ohm but when u play it after box rise it only "sees" power amp does at 2.5-4 ohms depending on how big box is.. so watt rating at 1 ohm doesn't matter it how much it does just above 2 ohm so if amp does 600 at 2 ohm sub only actually "sees" like 450 rms or so.. thats what we've all ben talking about.. your amp does same power at 1 ohm mine does at 2 ohm but what sub is getting is what your amps next higher ohm load is at best., so in this case i should get 450-500rms to the sub (even though amp tested at 930 at 2 ohm) just like your amp tested at 948 or whatever at 1 ohm but sub only gets what it does at 2ohm (little less than that)

Is this your amp? Their website says 1000@1ohm and 750@2ohm and 580@4ohm...just because you seen a amp dyno of one amp doing more it doesn't mean your amp will do the same.. all amps very and your amp could do 400watts less then the next one or could do 400watts more... only way to tell

Is clamp that mofo

Regardless your trying to compare a 15" fu to your 12" fu and your trying to compare running it at 1ohm to 2ohm.... just a stupid comparison

You are SO overthinking this.... You have a 1 ohm stable amp, you should have bought a DVC 2 if you only planned to play 1 sub. You can measure box rise and adjust for it, but you can't adjust for the coils.

yeah i really can't believe there no invention yet u can connect something to terminals raise and lower ohm load for like $10.. jbl has adjustable ohm load.. as i said i tried to change it it was too late and i woulda got d2 if everyone hadn't told me i had to have big 3 1st..

yeah i get what u saying but i was just trying to explain rise to him.. and that i understand he's running at 1 ohm.. but y everyone go buy xtr amps and price go up $100 after a good dyno if it don't mean anything?

Agreed, I don't know why the selectable ohm load is only for Harman products (Unless of course they patented it)

4 or 5 the peeps here said i needed big 3 and 0ga for over 1k on the other threads about subs... if i ask about sub peeps say u need better box i ask about box peeps say i need new sub so i'm trying to get both.. once i agree to do those they say u gotta do big 3 to run 1k.. like i said i had that power or close on ab amps yrs ago with no wire upgrades but i want my battery to get enough power to charge whether i upgrade wires or not.. i understand everyone wants me to run 1 ohm and i tried but it's done now, frank said it would be plenty power..

all i can say is, there is a good chance your pioneer will be louder than the fu because you dont have enough power going to the FU.

yeah i hope not at least box is bigger should help..
