if a speaker RMS is 2-70

and the amp outputs 111 watts per channel rms

will this blow the speaker???

not if you don't turn it up to loud.. you would notice distortion. adjust the gain so it's not to high at your normal listening volume.

No, a speaker can handle much more than its rated power when you use a xover to cut out the low frequencys, even being run full range they can typically handle alot more then they are rated for. Just dont try to run low frequency test tones at more than a speakers rated power for extended periods of time.

Use the gain setting tutorial and you'll be just fine...

If your gains arent properly set, then sure it can harm them. 70 watts is just a thermal rating, most decent speakers can handle more than they are rated. You shouldnt have any problems as long as the gains are set properly. Just make sure you dont clip the amp, and you should be just fine.

doesnt the head unit give 20 watts of RMS?

That or less, before clipping sets in...

is gains something on the amp you configure?

Read the gains section on http://www.bcae1.com before continuing...

a real 111w at 20hz for an extensive amount of time can possibly kill the speaker. 111w of 3khz for a period of time will kill your ears before it kills the speaker.


To be honest, you're not getting 111w. The power that an amp is rated at is usually at full power at a specific voltage and frequency. The higher the frequency, the less power the speaker will actually see. If you can cross the speaker higher, then they will be more comfortable handling the power. The higher the frequency you go, usually less power is going through the speaker. :)

IMO you can never have too much power... just impossible in my life

no probs
my 65rms comps see double that daily

All 3 drivers in my 3 way setup see more than twice their rated power handling and I've had NO problems.

so how can u blow speakers then?

Keep in mind there is a difference between actually overpowering, and simply having a larger than recommended amp on them. A 200w amp will not put out 200w constantly; it's highly dependent upon volume level, how the gain is set, type of music, recording level of the music, etc etc. So, just because someone has a 200w amp (for example) on their speakers, it doesn't mean their speakers are ever actually seeing the full 200w, atleast for anything longer than .1 seconds.


Then you have to issue of how the speaker's power handling was actually rated. Whether it's conservative, if it's the thermal limit or just the suggested power, etc etc.

i understand that but how can you blow them?

Three ways to blow a speaker:

1) Thermal failure; you exceed the thermal power handling limits of the driver.

2) Mechanical failure; You exceed the mechanical limits of the driver, which causes physical damage (such as bottoming out the driver, ripping the spider, ripping a tinsel lead, etc etc)

3) Physical damage/manufacturer defect; things like misaligned coils, dropping the speaker, etc etc.

i was giving my factory 4x6's 250 watts a piece and it liked it just fine

even tho from 25-35 didn't sound like any difference... just my .02

so if the amp is blasting 111 rms per channel and the speakers RMS is 2-70 that is ok???

If it's not, just turn the gain down a little more and the amplifier won't be blasting 111w, so it won't matter.


But there's way too many variables to say "yes that speaker will handle 111w."
