Crossfire BMF 1700d

Crossfire BMF1700d:

How does this 0-600 amp fair with other top 600w classed amps? do any of you have any experience with them? I used to work at a crossfire dealer long time ago but we sold cfa and bmf 1000d's, i loved them but i hear this new 1700d (which maybe isn't so new, not on crossfire's site) is supposed to be very underrated, and i have seen them go less than $300 shipped.
Anyone have any input comments on it? I'm looking for a decent 600w amp and considering the D5 but at about half the price this one is not too bad, but not sure just how it compares power wise at 12v to the D5.

They make 3300watts @.33 they are a good amp. But not in the same group as a d5.

Damn. That amp really makes 3300w?

well i have seen people say that the 1700w rating is 1 ohms@12v flat, and that .35@16v was 3k+, so when you say not the same group, your saying the D5 can make way more than that? The reason i ask is i have seen people say that the D5 makes between 3k-3800 but i don't know for sure, impedance - impedance, voltage- voltage how they compare..
i'm basically looking for a 0-600w amp that can perform on stock voltage without having to go 16v or higher. I know that it is not always linear and some amps may perform better than others at higher voltages, while the same may not be true with the same amps at lower (stock) voltage ratings.

There is no 0-600 amp that can beat a d5 @ any voltage the dd m3a's. Are close but they are not legal for 0-600 because of there 750@4 rating they originally posted

Basecort knows more about those Crossfire amps he will tell what he thinks when he reads this

so excuse my ignorance on the M3, but is there a difference between a M3 and M3a? Is M3 short for M3a, or is the A a revision to the amp? I was under the impression (although there was some arguments over it) that the M3 was a legal 0-600 amp.

also, i assumed the D5 could lay down the law on the 1700d seeing as how it simply is built and physically a way more beefier amp.. 2 pair of 1/0 inputs vs 1 pair.. yea.. but i didn't know by how much. I asked sanman but he has not tested the 1700d

Thanks Chris. Last year at finals we clamped the jeep and 2 on 16 volts at .175 each did 4100rms. So 8k rms not bad for a rated 3400 watts. They are only .3 less than a d5 doing a direct swap at .25 each amp. They love .25 and .35 daily. I clamped 2600 rms at 1.1 after rise at 12.9 volts on a burp in my trunk car. There bullet proof and have lifetime warranty for team members. There local to me so I have no problem running them. And all clamp tests were done by me and roger at crossfire or finals.

Also they are a 0-500 amp. Rated 425 @ 4 ohm on the new manual.

so they take .25-.35 daily (music)? well i found one for 275 shipped, debating on getting it, but i don't wanna cut myself short when i have more headroom for power in 0-600.

The m3a's are a all new amp! They came out with a higher rating than lowered it on the website. . This amp has not been usaci tested.

gotcha

Im not sure im buying the. .3 off a D5. Your clamped numbers don't equal that to me. Im sure its a nice beefy amp. But D5 makes a bit more power than that.

M3a is approved by ralph himself for 0-600 unless protested

the d5 will eat the crosfire amp up man

yall might have had other issue causing this to be such a close comparison, but beleive me the d5 i alot more amp than that

also chris is close but not quite there yet lol the cactus pf600.1, and the treo 4.1 is the closest thing to the d5

4.1 needs a Dung Pile ton of batts for power
cactus is a 600 watt amp, and needs to be modded for more than 17.1v and is unstable

we clamped the crossfire a few days ago starting at .5 rise to 1.6 did ....2,100w

I still say the m3a's are the closest thing to a D5.

Ppl don't give the 1700s enough credit but are beast for sure and yes .3 from a d5 it was. But .3 could be like 500 watts difference the d5 has on the 1700. For the price of 2 1700s compared to one d5 they will beat the d5... Be cheaper... And not take up much more room at all.

And have twice the 4 ohm rating of a D5. A D5 will do over 6k on 16v. There's no reason for an amp making 3300 w to only be .3 off. That's your enclosure or weak battery not letting the amp work. A d5 will walk a 3300w amp of off 2 12v battery.

I'm just telling u what we tested. And on 16volt the crossfire did over 4k so .3 is about right. How many ppl actually get 3 full Db when doubling power. But anyways op I'd get the crossfire for that price

But a D5 does that on 12v ..

Say u "expert analyst lookin mutha!" Lol. I know a d5 beats it all day I'm just saying... 300 bucks or 700 and up for a d5

Omg a dude from texas that likes crossfire????

I don't think there's currently anything feasible that can hang with the D5 in any capacity after its said and done.

Well until roger gets me a handful for the civic trunk imma argue lmao.

There's no argument I know the d5 beats it but dude asked if it was good for the money. It's actually best for the money. I mean a true 3k on 12volt amp for under 300? Find another amp to beat that deal

wropng best bang for the buck is a MMATS 3500.05 hands down

also i can get 200.1's for 400 bux all day long

Well I wasent worried about the guy asking if it was worth 300. Im very sure its well worth 300 bucks all day long. And if usaci didnt have silly power classes it would be a completly different convo. I was commenting on it making 3300w and playing .3 off an amp im 100% sure makes twice that. But also. Didn't you say it needed 16v to make 3k+? If these amps do .3 off a D5 then I def need 2 for 0-1k but im willing to bet I only see a mid 55 at best..

its not .3 ide be willing to bet around 3 db off

Does over 4 on 16 and over 3 on 14 volts. And screw mmats them badass power inverters lol. And I said 300 not 400 so for 300 this is best amp you will get sanman.

Ps sanman why do u comment on every thread Alan hall does? Just seems weird
