Speaker to Amp question.

I have a pair of MBQuarts with 50 W RMS and 120 W Max. I wanted to know if I hook those up to a 2000 watt Boss amp, is that safe if the bass boost is all the way down and the input level up just a tad? Cause I know Boss amps don't really put out what they say they do and I'm still a scrub at all this stuff.

So long as you keep the volume on the radio at the proper level, it's fine. Crank it up too high though, and you may damage the speakers.

If you're blowing speakers already, it might be a sign you can't be trusted with that much power.

Nah, stock speakers are blown.

That's like sticking a 1200hp Viper Hennessy engine into an other wise stock G?35, and asking if you drive it easy will the OEM clutch hold up. I hope this thread question is a joke...

It would be, but a boss amp claiming 2,000w is like a 16-year old claiming the bolt-ons on his VTEC civic give him 600hp. Just like how the "600hp" civic can destroy a 300hp-rated clutch when used wrong, the "2,000w" boss can ruin a speaker rated for only 50w RMS.

It is 200wRms x4 @ 4ohms, and that is just plain to much for 50wrms speaker. Its not if they'll blow but when they'll blow.

probably more like 50 x 4, not 200.

Okay heres the thing with speakers and amps, higher RMS watts (not peak) do not destroy speakers. Clipping does.When you push an amp to the point where it cant make the power its designed to the waveform changes from a sin wave to a square wave. That what destroys speakers. I had a Treo TSX 15" sub and it was rated at 500rms I gave it about 1200rms from a RF T1000.BD and that amp can def put that out. It lasted for a long time, until the tinsel leads broke from overexcursion. I made the box larger then recomended to give it a deep tone I was looking for. The coils looked shiny like a new penny, and was repaired and still working according to the next owner.

Next that Boss amp doesnt put out 2000 watts at all. But a watt is a watt. What Size fuse does that amp have on it?

MQ quart (before Hifonics bought them) made quality equipment. It should be fine, over powering is safer then underpowering anyway due to what I explained earlier clipping.

Next question is im assuming its a 4 channel amp correct?

If you got it, use it, adjust the amp accordingly, RMS loads are thermal recomendations anyway. Depends on how you listen to music. IMHO buy a different quality amp.

The amp is 2channels and theres two 20 fuses.

I'll probably just hook em up without a amp for now and buy another amp in a week or so. Class just started back anyway, so it'd be quicker to just replace the speakers for now.

Okay this is the math I use to determine how much an amp can do (no its not 100% accurate but it gives you an idea)

Take 14.1 Volts (which is around the charging voltage you "SHOULD" have at your amp)

Then multiply the fuses by the voltage it will give you wattage. Thats if the amp was 100% effiecent, which it will never be.

The max that amp can produce with only a 40 amp fuse will be 564 watts @ 100% effiecency

To be fair lets say its at 60% thats about 380 watts that amp can even produce.

Being a 2 channel youll only have left and right channels or front and rear. Its not the best solution unless your only running a good set of componets for front stage and subwoofers.

Hooked em up with no sub, figured in the long run it'll be cheaper getting a new amp instead of risking blowing the speakers and having to buy a new amp anyway. Still sounds much better then stock though. Still gonna have to amp em though, 1800 watts isn't forgiving with bass versus vocals.
