Honestly though theres a lot more variables then just rms and max. First of all never look at max EVER look at rms lol.
Some variables that should be considered:
Head unit clipping point
Amp clipping point
Head unit voltage out
Battery voltage
Box specs
Sub specs
Amp specs
Box rise
Cabin gain
And box tuning are some of the the more important things you should look at. If you don't know what any of those terms are then you should either do some homework or let a professional audio shop handle your system lol

This one is very informational teaching about what clipping is, and what it does to damage the woofer.

I just like how it shows that instead of propelling the woofer it starts to hold it back and forward. That's a big reason I decided to upgrade my system a bit. It happened with mine all the time. I had a 150w Kicker 2 channel amp bridged to my sub, but even with the gains and bass boost all the way up, the sound was just adequate but it clipped like mad. Anything less than max on both and I barely heard the sub. Now I'll have it on 250 watts so it should be better.

Too little power won't burn up the voice coils, but a clipped signal from trying to push that too little power will.

I like to have tpo much power so I can properly power my subs and keep the amp turned down so it doesn't work hard either.
Finally ! Someone on here that knows what he is doing !

That junk was wired all wrong and the subs were in a shared chamber so the 1 that was left bottomed out while it's voice coils were melting.

NO ! 'Max' or 'peak' mean nothing ! Match RMS only, use a lowpass filter, use a subsonic filter if using a ported sub enclosure, and set the gains correctly.

GLH, you kinda come off as an ass, but in all honestly, you know what you are talking about most of the time, haha. You should consider doing an in depth write up on sound systems.

No not usually. Clipping can be very subtle but damaging. That's why its recommend that they be set with an oscilloscope or similar device.

When doing some research on subs and amps, I found most system manufactures recommend the amp be between 80% and 120% of the sub's RMS. That's the easiest way to avoid clipping and overpowering your system.

Must know tips for new system shoppers:

-RMS is everything, Peak means nothing.

-Different impedance's will mean different RMS, make sure you are looking at the right RMS for the right impedance.

-If you're not sure, don't assume. Ask someone competent. Avoid costly hassles.

You need a lesson on setting amp gain and general overall setup.

No such thang as 'max' or 'peak' wattage. Amps and subwoofers/speakers should be matched by using RMS wattage specs.
I'm just saying that if my guess is right, that my amp is two channel and rated 300 per channel, if I bridged it then it would be 600. On the box of the mtx was I think 200-250 rms and 400 peak. That's what the box said. Like I said. I set all settings on the amp down then played a song and set them to appropriate levels. Not extreme like gain 3/4 the way. It was more like a quarter turn until I heard good bass. It blew. I bought a kicker cvr for 25$, Says max is 700. Rms, no clue probably like 350. Idk. Same bridged set up and set it to appropriate levels. Lasted for a year and still going, my amp is a coustic 600se. It's yellow and silver. It's huge compared to another amp of same rating. I think it might be older model. I wasn't looking for something that's going to rattle me to death. It has a great sound. Then when you set the headset to loud, it really pumps bass for one ten. Keep in mind this is my first system for any car, i did all wiring myself. Pretty clean install.
