It is impossible for too little power to blow a sub. Period. Like I said before, low power amps driven into clipping might blow some subs by overpowering them.

I have never blown a speaker from providing it with "too much amplifier". Too much power? Of course, but this is where judicious use of the "level matching control" (i.e. gain control - an inaccurate label, at best) comes into play.

I am running WELL over 600 watts to each door in my car (340+ to the bass (adire Audio 6.8, rated 200 watts RMS), 172w to the mid (Vifa carbon fiber mid, rated 10 watts. Yes, 10 watts!), and 172w to the tweeter (JL Silk domes, rated 80 watts peak)), and I can tell you that I never hear any thought of stress. This is because of the careful tuning I did with the system as I was installing it.

DYohn is right. It takes a long time to be able to hear distress in electronics, and even longer still to be able to discern which device (speaker, amplifier or signal source, in this case) is the offender. Lacking this experience, the link provided by DYohn is a very informative one, and one that should be read thoroughly.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Distortion kills subs, if you have less power you will try to turn it up more driving it into distortion and killing your sub.

I run 11,000 watts to 2 5000 watt subs (maximum) and Ive never had a problem!

Gti 15's they are 800 RMS and i feed them 2600 RMS each, with 3 batteries and a 20 Farad cap

never had a problem

Have you ever seen an Acura with them butterfly doors???

audiovibe-mike, im gonna call you on this one. first, if you go back and read DYohn's responses you will see that its NOT distortion that will cause the damage, bur rather heat. second, you are not running that much power through those speakers(no matter how much you believe you are). if you were they would not still be working. now, you may have an amplifier that is rated with more power than the subs you have connected to it are rated, and if that is the case you obviously have it adjusted correctly and do not run more power to them than they are rated at. like i said earlier.....if you did......they would burn up. David, whats your verdict???

Good "call"... I'm with you as well.

Wrong answer. Power kills subs, not distortion. Read the thread linked to by DYohn...

Again.. Wrong answer. What you MEANT to say was this: I have 11000 watts of amplifer CAPACITY (shyah, right...) connected to two 5000 watt subs... Not to mention that only 1000 watts more than the drivers are rated for, is less than a 10% RMS overpower situation. I'm FAAAAR less than impressed. Try a 1700% RMS overpower capability, and not blow your driver, THEN come back and brag about never blowing a driver. (See my previous post regarding running a 170 watt amplifier to 10 watt mids...)

Nope... Another bad call. You CANNOT power ANY driver with more than it's RMS capability in an RMS situation without blowing said driver. Your amplifier may have 2600 watts ON TAP (another "shyah, right" fits here...), but you are never feeding more than 800 watts continuous to the woofer... The laws of physics dictate this to be true. If you belive that the laws of physics cease to exist in your trunk, or if you think your amp makes that much power, and you really believe that you are cranking your amp, connected to 800 watt woofers, and you are not blowing those woofers, you need to do a bit more research into what a quality amplifer can actually do.

agreed ham...11,000 watts and ONLY three batteries??? that cap isn't doing squat either...Unless you have dual 250-300 amp alternators you can't charge squat with the system turned on.

Its number 4 acura 99 3.2tl on cardomain check it out. silver with lambo doors.

If your saying that my amps dont produce those amounts of power i agree, like i said its no crown. but thats what the ratings are. I have lots of pics and trophys. I run the two amps strapped at 1.5ohms, for 11,000 watts. max. in a perfect world i know, but those are the ratings. I dont see why you have such a hard time believing it.

The proof is in the pics.

p.s. i am new here and dont wanna stir doodie up, if you know what i mean. Ive been installing for 4 years, im 22. i know im not an expert or nearly as knowledgeable as some of you guys, but i joined cuz i love cars and 12 volts :)
