are jbl amps any good? (for car audio)
They're not bad, if you get a good deal on one.
they are what i would call lower-midline stuff...good for the average consumer that just wants upgraded audio vs those that want competition grade stuff
pretty decent bang for your buck...
edit: They're actually decent enough for subs...I'd think twice about putting them on my components though
more specifically the jbl bp1200
The only one I have experience with is the 1200.1, and it was a nice amplifier, if you can get it for less than 300 dollars I would say its a pretty good deal.
i got 2 of the jbl bp1200...
do you think its ok if i hook both of them up to a adire brahma 15
i have the 600.1 running my subs.
does great, and I got a great deal on it.
wouldn't run interiors off of jbl stuff though
I wouldnt reccomend it. 2400 watts to one Brahma would be a lot more than you need, unless it is for SPL competitions or something. Or if you have it in a rediculously small box.
You would most likely toast it with that much power.
yeah but the max on the adire is 4800w
max != RMS
It probably will take the 4800w RMS...for a few seconds, before it burns up...check your RMS rating and go based on that.
RMS != power handling without a time constant or signal type
that would be stupid
yeah yeah, but now we're getting more technical than we really need to
so just 1 jbl 1200 to one adire brahma 15?
The max on some Pyramid subwoofers is 1000 watts, yet I would not give them more than 200.
You can get almost any subwoofer to handle even 10,000 watts of power for a fraction of a second at a high frequency. What does that mean? Absolutely nothing, because with music, it cannot handle that kind of power.
If people didn't clip their amplifiers and didn't play bass music, you would not get as many destroyed woofers, because the crest factor (rms to peak) is pretty high, even with most rap music. If that was the case, 2 1200.1's would be fine on the Brahama.
But I doubt you won't ever clip the amplifier, and continued power of over 3000 watts to a single Brahma can very well cook it over time.
does the jbl bp1200 actually spit out 1200w?
Not really. I can say the thermal RMS power handling for a Pyramid 15" is 2000 watts RMS.
All I have to do is play a 1khz tone free air at 2000 watts RMS for say a second.
You could not get sued in court over making a claim like that, because it is 100% true.
Adire could rate the Brahma for 10,000 watts RMS because Richard Clark hooked it up to one of his huge General Electric amplifiers and took it for a second. But they are honest with their consumers and know that a more fair power handling rating would be using one of the EIA standards.
Its too bad there isnt a specific power rating system in place for woofers that wouldnt allow for this kind of variation. Home audio equipment has the FTC standard for power ratings, but even to this day, not many manufacturer's follow it, and it only conforms to amplifiers, not speakers.
Yes. When you clip it, it could get close to 2400 watts.
so what kind of box would you reccomend with a jbl bp1200 to a brahma 15?
Yes, that should work great.
1. What kind of music do you listen to
2. How loud do you want it
3. How much space can the box take up
4. Are you more interested in sound quality or output
what do you mean by "clip it"
sorry im not that good at car audio
