Any of you guys used this amp, i am looking into buying one and just looking for some feedback on it, and if the 2000 watts rms @ 1 ohm is true

how much is it? if its 2000x1 rms @ 1 ohm and its less then 1grand new, probably not true.

well I have the 1000bx
1000 watts rms at 1 ohm....
to me its the best amp Ive ever used....I love it

and if youre intersted Im selling...lol

just had to

hifonics makes some good amps so it will probably make 1500 to 1800 at 13.8 volts. but make sure you have the electrical system to handle those loads( like an high output alternator and a capacitor and a good battery). because if you don't it will probably shut off a lot and be distorted.

My RF T10001BD was under $1K, actually $400 new it puts out 1400watts at 1ohm and it is CEA2006 compliance. Anyways the Brutus was what I was looking for before I got the RF, decided to pay a few more for the RF instead. Out of all the research I've done the Brutus you got more bang for the bucks if you are running a budget.

maybe off of ebay you got it for 400 new one no? the amp is 700 new, and i did forget about that one, but as far as getting 1400 out of it, not likely. It does 1000x1 at 1 ohm, i know rockford underrates, but not that much.. you will possibly see 1100 out of it.

According to the birthsheet (need me toscan it for you too?) and like i said w/CEA-2006 specs. And I bought it brand new (in BOX and still wrap) from a shop in philly no EBAY ____.
And also the RF I got is not the normal run off the mill bestbuy special.

But to the OP check out soundillusions.net read their forums and check out what others say about that amp. Like i said for running on a budget its a great amp it will do its rated power.

pollup have you ever heard of hifonics before. just curious cause it sounds to me like your pulling #s outa you but.

ive heard of the brand, but very unfamiliar of the quality.. pulling #'s out of my ___? how do you figure, the numbers i threw out were for the rockford, not hifonics. as i still find it hard to believe that rockford pushes that power, but if his test sheet says so i guess its so then.

oh my bad

indeed, my RF 501s is 500x1@4ohm but birthsheet says 632RMSx1@4ohm....

I've always heard good things from hifonics....especially about the good price.... but you'll definitely need some upgraded electrical for 2k watts.... Big 3 wiring upgrade, 0ga power/ground, better battery, maybe even an alternator rewind... forget about a cap, they don't help like majority of people think they do....they'll not help in this application very well anyway...

im running 1.7kw off stock alternator and a 50 farad. that cap has enough juice to start my car though.

take it with a grain of salt if you'd like, but I'll never use a capacitor in any system unless it's a dedicated SQ vehicle running LESS THAN 800watts of total power... too many people get capacitors thinking it'll keep you from pulling straight from your alternator and dimming out your lights... they're just a band-aid for a bigger problem - being insufficient amperage...

I disagree, when doing spl comps and burping the system its easier to have a ready source of power then to try to draw from what ever amount of feet you have from the battery itself.

so are you saying that you drive around town listening to 1 or 2 second clips of music at a time???? didn't think so... so what's the point of a "50 farad" cap in a daily driver??? and how do you explain Alma Gates Bronco with 10+ High Output Alternators in it?? what?? no capacitors?? they're a waste of money....

as I said, take it with a grain of salt if you'd like, I don't give a falk...

And what has to charge up that cap again? You music is playing cap went down alt has to charge up a cap while trying to produce enough amps to run the amp to play your music....

Caps waste of money



Oh by the way Alma Gates Bronco has 12 alternators... :lalala:

no, i dont drive around listening to 1 to 2 seconds clips lol, but i dont go around bassing anywhere near full blast. the setup i have is for competition, although i have the ability to drive around with it loud, i dont. alma gates is in a world of her own, thats all i can say about her. shes nuts, but shes also producing a world more of power then i am. also keep in mind she may not have caps, but she has a ton of ready service batteries in the rear, close to the amps, correct? what do you think a 50 farad cap is? its a rapid discharge battery, thats all.

imo for competition a cap is more then worth the money.

Go to an audiophile forum and tell them your 50 farad cap is worth the money.... you'll be laughed off the board... like I said once, I don't give a falk what you say or think... it's your ____ do what you want... go dry your ears at icixsound.com for a while

lol not looking for an argument, only paid 80 bucks for the rf cap, if i wanted to sell i could make more then triple what i paid so its not reallly sweat off my back. thanks for the info though.

es todos bien

es todos bien

si. makess me happy :)

your talking about band aid fixes SCI_TC_GUY and you want to advise this gut to "rewind" his alternator. thats a bad way to get more amps you should always purchase an alternator made for higher output. also if you think caps are a bad thing you should pick up the last issue of car audio mag. and read about the new rf amp with caps built in that runs more than 100% effeciency.

all amplifiers have caps built in to an extent, inside my bd there is 6 decent size amps, i havnt totaled up their capacitance though, and i really never thought to until this topic :). its all good though. my system hits, my lights dont dim, i dont nor have had any electrical problems.

Which amps are these taht you are talking about that are over 100% efficiency... :blah:

its called the rockford fosgate t15kw. here is a quote from the beggining of the article: "rockford fosgate has devoloped a new concept in amplifier design, which they unveiled at the 2006 consumer electronics show in the form of the attention getting t15kw the gist of this amplifier is to store ungodly amounts of wnergy, enabling to produce 15000 watts at greater than 100% effeciency." there is a 2 page article on this amp describing haow it works bu i'm not they gret of a typist so find it at rf or car audio mags website but it uses the same capacotors that are used in electric vehicles.

yeah and $20K for it, talk about an amp that does over 100% efficency that is at at normal price then talk to me.

its the first one of its kind its going to be expensive. its to prove a point read the rest of the thread.

a good motor shop can rewind an alternator to effectively produce more output... any reputable shop will give you a warranty on their re-worked product as well... for 1/4 of the price of a H.O. alternator, you can have the same output.... if you've got the $$$, buy a H.O. alternator but I've always heard of people having problems with aftermarket alts... far fewer problems with a rewind that I've heard of from a daily driver... and yes, all amplifiers have capacitors in them...

ok, you have your opinion and i have mine. a cap is used because on 13.8 v charging system and with a regular battery when heavy bass hits the battery cannot release enough energy to sustain the note, capacitors are specificaly designed to release the juice faster it is a helpful item on a regular persons system. and as for the rewinding of alternators thats just wrong. go to any shop building a high output system or look at any factory built show car (i.e. alpine, mtx, kicker.) and see how many "reworked" alternators they use.

and on a bass note that's sustained longer than a few milliseconds, your cap will be drianed and you'll be pulling from the battery anyway.... cap discussions always lead to nowhere so I'm done with this thread..
