Running your subs on more then rated power

Personally, the line is drawn by knowing your own equipment. Knowing you mechanical limits, thermal limits (knowing when to back off, whether you smell the coils heating up, dustcap gets warm/hot), and how your box plays given frequencies.

There many dyno videos and like most amps TS sends a test page of what they got on that amp at what voltage. And yes the amp is rated 2.8k on your typical 12.8-13.3 electrical system but like I said at 14.4v it will do easy 3500 @ 1ohm

The only way to know for sure what your woofer will see is the clamp it ;-) Your electrical needs to be adequate for the amp to actually make the said power output. Like the others already said, many variables exist. Type of music, is the signal clipped or not, how long are you playing the music at any given time, etc etc etc....

I've ran many many speakers with way more 'intended power' than the RMS rating of the speaker, and never have problems. And yes, if you push the speaker to it's limits often, it will wear out faster.

You guys are thinking way to hard about this, I feel. If the gains are set correctly, all you have to watch is mechanical (make sure it doesn't bottom out/jump the gap) and monitor heat under whatever power is applied.

If you have quality soft parts, other than break in early on, as long as it is kept within its limits, it shouldnt ever "wear out".

Clamping an amp that is playing a sub will always show more power than is actually being applied because the voltage and current are not in phase with each other. One way to get a true measurement would be to clamp it with a resistor bank instead of a sub.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

with a 4.75 cu ft box ur box rise is atleast between 3 n 4 ohms(just guessing cuz its a big ass box), my box is same size tuned 38hz runnin hcca 12.2, bigger boxes are for if ur gona under power the sub, the bigger the box the less power ur sub will handle, get a slightly smaller box and buy an amp thats rated atleast 2000rms at 4 ohms lol good luck
