How good are crossfire amps?

Question

I got an offer on a 400w 4ch crossfire amp. The guy wants $40. I dont know the model or anything but what is the general quality? Does it sound like a good deal?

Answer 1

Don't listen to doug or george. Doug's friend is probably an idiot. And george doesn't like anything that's not made by elemental designs.

Crossfire amps aren't bad at all. Most high end audio shops that sell them, sell them as their secondary brand. For the people that don't want to spend 1800 on an audison. It's not the ultra high end. But, it's better than most of the mid level brands. They are a competition grade amplifier.

For forty bucks, I would assume it's an old VR404. In which case, it's not a bad deal.

Answer 2

NO

when it comes to car audio nine times out of ten you get what you pay for- and you need to look for CEA-compliant brands which means that the amps have been tested and produce or exceed the advertised RMS wattage with minimum distortion and the subs can handle their advertised RMS wattage also

here are the top CEA-compliant brands

Alpine

Bazooka

Blaupunkt

Clarion

Eclipse

Infinity

JBL

JL Audio

JVC

Kenwood

Kicker

MTX

Pioneer

Polk Audio

PPI

Rockford Fosgate

Sony

if you send too much power to your speaker, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your speaker — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the speaker and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the speaker

you will send the amp into clipping

Clipping

Clipping occurs when an amplifier is asked to deliver more current to a speaker than the amp is capable of doing. When an amplifier clips, it literally cuts off the tops and bottoms of the musical waveforms that it's trying to reproduce, thus the term. This introduces a huge amount of distortion into the output signal. Clipping can be heard as a crunching sound on musical peaks.

that causes distorted sound which will damage your speakers

Answer 3

no good at all my friend had on and it sounds bad

Answer 4

It would still be a bad deal even if the guy was giving it to you. Crossfire amps are right there with Legacy and garbage brands like that. You would be better off looking else where for an amp.

Answer 5

"Surprisingly, too little power can also damage your speaker — in fact, it's actually more common than damage caused by overpowering. "

Totally false. If I turn my volume down, I'm doing damage?

Low volume = low power.

Underpowering does NOT automatically mean clipping. That's due to too small of an amp with the gains set wrong.

Here's THE TRUTH!!!

never heard of it, sounds like a legacy,  You need to get reputable name,  rockford and alpine for example, although there are so many good amps out there it's hard to choose.  rockford, mtx, alpine are some of the most popular names,  but you can dig in and get an alphasonik, or hi-finocs, off ebay that will serve you real power for that same buck.  Remember to look for the rms wattage because that's all that matters.
