Fp24000




4200W*2 channels at 8 ohms
7500W*2 channels at 4 ohms

I don't really get this.
It has less power than the FP20k bridged at both ohms, so why would we buy this?
[email protected] x2 and [email protected] x2 LOL!
Unless maybe the 20k doesn't actually produce it's claimed ratings and these do? or this is dual 2-ohm stable to 16kW or at-least dual 4-ohm stable at 7500?

Weird product IMO...

At least with the 20k you can unbridge it to power 4 discrete subs with independent EQ.

If this thing could do 10000w @4 and 16000w @2 then that would be worth upgrading to. But I doubt that it does...

Wouldn’t those basic speaker wire terminals be potentially deadly with that much voltage? Seems like any connection using that much juice should be totally concealed in some type of protected cover.

Those are pretty common numbers for car audio amps. There are several that can do 20k watts in to a single channel and some that claim 30k. If it was deadly dangerous then you would have heard about some redneck killing himself that way. The more alarming part of that is the dc amperage that they pull. Sometimes several thousand amps. If it arced you would have one hell of a problem.

Don't confuse voltage with wattage.

I am not confused with voltage and amperage. E x I =P i understand that this amp is running at 240v AC but once on the way to the drivers you should be on the same plane. What i was saying is dangerous is the large banks of LiPo batteries that these guys build up to keep the voltage from sagging and dropping their power output. Maybe i am missing something but that is the way i was looking at it.

12volt is safe because it can't arc through your nerves/heart.

BUT... get a finger near the arc weld point and it will blow your finger clean off (and molten slag/shrapnel in your eyes).

Even AC can be dangerous as you know. But you'd have to get body parts between the pos and neg terminals while pumping high sinewave bass at near full output.

In any case, let Darwin sort them out!

Yes, you are confusing them.

This amp can output almost 300v across the speaker terminals.

Car audio amps are not really doing this. They run at higher current into lower impedance loads at lower voltages.

Ok. I stand corrected. I was assuming they were similar. I will admit i don't know much about amplifier topology. Just a dumb electrician here.

Sinbosen. But I don't see the 24000 on their website. They have the 22000 which looks like an upgrade over the 20000 though.


Why are there only two screws for each fan? Never seen a cpu fan that didn't have four screws.

Delta 40mm server fans. They have both 2 screw and 4 screw mountings although they won’t need more than 2.

They sound like a turbine engine, no joke.

LiPo batteries in an amplifier?

I think he was confusing the capacitors with 18650’s, they do look similar.

Nah, he’s talking about the spl comp vehicles. Step one, pour a couple inches of concrete on floor and walls in back of suv. Step two, solid later of batteries above it. Step three, enclosure and amplifiers.

Chris is correct on what i was thinking. This is a YouTube video going through them. I use to do car audio and have been having bad thoughts of trying it again but i know i will go to far.

This will probably sustain at lower frequencies better at the higher output levels, maybe a bit. It could also be a while before the get it sorted out and get all the flaws out of the design, something to consider. If they went to 3RU and really upped the power, then I could expect some potential improvement, but right now I would expect they are getting about as much as they can from standard 2 RU chassis. Go to 3RU or make 2RU 30cm more depth, then there is potential. Too bad everyone wants to save space, whats wrong with a tall rack of amps?

Why not just stay with what works and at least let them get the quirks of the new design figured out .

I definitely won't be buying it. The 20k has sufficient power density for my needs.

You mean 20 of the 20k

A Good amplifier requires a adequate power supply, It does not matter what the amplifier is capable of if the power supply will not provide the power required. Most amplifiers have under rated power supplies. It is up to you to make sure you get the ones that are least under rated if at all.
