sounds like he was doing his job and trying to scare you into buying an amp

 

Isn't that like saying when the volume is low it can blow the speakers? It doesn't make sense. I mean even if it's amped and the volume is low...

 

VEEMAN said this "Low power can not blow your speaker, otherwise everytime you turn your volume down you'd essentially be underpowering them and eventually blowing them."

 

timmay2tokes is probably right. futureshop is still on commission arent they? he was just trying to sell an amp. and possibly but not as good of a chance. sell him a new pair of speakers.

 

We all know good comps need decent power and deck power can't give it out. So users clip it (even if they claim not to hear it) and the clipping can heat up the coils much more then regular power.... and thus we end up with craped out drivers, especially tweeters I would assume as they would be more prone to damage because of straight DC.

Your FS dude probably isn't aware of the above BUT I am sure he is aware of lots of returns do to un-amped comps.

 

Well the guy said some dumb "They shouldn't of lasted 2 days, They can blow without you even needing them to turn up loud".

What he was saying was "Come in side, And I'll show you some bullshit over-priced MTX amps we have"

I ran a set of Infinity Reference 6.5 Components for 4 years without an external amp and never had any problems.

I honestly think you really have to crank components to death without an external amp to blow them.

He said if he installed those for me he wouldn't even do it, because they would blow really fast...

 

I found this on the Basic Car Audio Electronics webpage.

* If your speakers are capable of handling significantly more than your amplifier can produce, driving them with a clipped signal will not likely hurt them.
* If the speakers can handle 3 or 4 times the power that your amplifier can produce, there's virtually no way to damage your speakers (no matter how clipped the signal is).
* If your speakers are rated for the same power handling as your amplifier is capable of producing cleanly, driving them with a clipped signal for extended periods of time may cause speaker damage and/or premature failure.
* If your speakers are rated for the same power handling as your amplifier is capable of producing cleanly, driving them with a square wave signal for extended periods of time will likely cause speaker damage.

This is pretty much what I went by (I love this website).

 

Google search "Some Facts About Distortion And Speaker Damage - by Richard Clark" as originally published in the Autosound 2000 Tech Briefs.

Unfortunately the formatting of the document is not the same as the original publication so it's a bit harder to read, nonetheless, there is still a lot of very worthwhile info in this article.

Cheers!

 

The guys that typically damage their speakers with deck power are the ones with a big sub system and their sub amp gains maxed. They turn up the bass and then try to match the mids/highs to bring some level of balanced sound to the system. This causes the deck to clip and overheat the standard speakers voice coils (most typical 5.25-6.5" speakers are rated for around 40-60 watts rms) and eventually cooks them. Contrast that with a more experienced car audio guy, and you'll find he probably over powers his speaks by 1.5-2x their rms power and has a balanced sub system with the amp's gains set low. When the system is cranked you get clean power, low noise and and lots of dynamic range as the peaks and valleys in the music signal can be reproduced due to the headroom available in the amplifier. The speaker's cone can move a lot and stay cool, and the system sounds louder and much cleaner.

 

because its on the web dosent make it true..first off.. clipping wrecks speakers period.. so statement one is wrong.please confirm with any speaker engineer on this.. ex. scott bwalda of hybrid audio or pat turnmire of red rock aqustics.
distortion eats speakers.. no matter what the volume.. see above for reference.. ex. if i take my honda civic and drive on pavement i can do any speed in the tolerence of the car.. but i take it off road and go two miles and hr but still destroy the car.. humm its says it can go 10x that fast why did it break... speakers are like that. it will due 100 watts clean, unclipped sound, but hell it aint gonna last with clipped and distorted sound very long no matter how low the volume.
there are problems with 3 but i can live with most of it..
same with 4..
please understand speakers are a very crude and archaic sound reinforcement design, they are very inefficient, and limited as to what they can due.. when you start messing with power specs, distortion clipping and volume. well its really like throwing darts at a board as to how long a speaker will hold up... follow simple listening protocal and use common sense and your ears and components will last a lifetime..
