Is 75w rms too much for 40w rms speakers?

[RebelExtrm02 10+ year member]

I have an amp that puts out 75w rms per channel and I wanted to use it to power my door speakers which are 40w rms 6.5" coaxial speakers. Will this be too much for the speakers to handle? The amp is an Infinity 475a.

It depends more on the type of speaker not the amp. Some speakers might be able to handle it others not. You really need to give more information.

yeah more info. i run 90 rms to my 40 rms mbquarts but they are quarts they can take it a 40 rms polk, pioneer ect would cook.

They are sonys so I'm assuming they will cook lol.

 

[pieper88 10+ year member]

Yeah I don't see sonys handling that much.

sorry for post dumping but same question but what about a set of eclipses think they can handle 80 lol sorry again

 

[pieper88 10+ year member]

again need for info model number, ratings, etc

Troof ^^^

Sony rates their shit in "theoretical watts" assuming a bunch of bullshit variables that most people would never consider.

When TRUE actual power is given to those things they go //content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif

Couldn't I just set the gains on the amp low to limit the current available to them? Each channel on the amp (front/rear) has its own input level control. Is input level even the same thing as a gain control? The amp is this amp Infinity 475a

After inpendance rise you'll be closer to 40w.

Just take it easy on the gain, you'll be fine.

Power doesn't kill speakers, people do.

I've kinda always pondered that. I know sony's are pretty much the low end of low but I'd still be interested in knowing if the ones that died at rated rms wattages also had all the other settings such as gain and whatnot set right to keep them from distorting to pieces. :/

I'm still debating hooking this amp up to them or just leaving them run off the head unit and selling the amp for a mono block and only amping the sub... I'm getting pretty mixed opinions here.

remember. Your speakers will only see the wattage that you allow them, no matter what you set the amp to. AKA, your volume knob is a voltage control, so if you set your volume knob to send enough voltage for your amp to produce 75 watts it will make 75 watts.

Speakers will let you know when they have reached their power handling given the alignment they are in. 95% of people have NO idea how much power they are ACTUALLY sending. Of course a lot of people don't own a clamp meter.....

and headroom is always a good thing....

They would probably take it as long as you dont crank the volume. I have my rear stock speakers taking about 90 watts.
