That you need 0.1 farads of capacitance for every 100 watts of amplifier power.

and that capacitors fix all your electrical problems.

that there is such thing as a "digital" capacitor, and that "digital" capacitors are better than regular capacitors

(that little LCD display adds at least 10% to your RMS power rating you know)

1. Gain = Volume

2. The wattage rating the company presents is a true representation of the amp's potential.

3. Listening to a sub in the store is the same as listening to it in your car.

Just a couple of the myths I've come across.

1.Rockford fosgate is the loudest and holds ALL the world records (all the kids in my area believe this one)
2.higher price = higher quality
3. 130 dB can break windows ( how many people have heard sony X-plode owners say, "I can't turn it up or my windows will break. )

BTW, a gain by all standard electrical definations IS a volume ****.
A gain is technically a potentiometer, which is:
A three-terminal resistor with an adjustable center connection, widely used for volume control in radio and television receivers.

I was going to say, I thought gain was a volume control of some type. I mean I don't constantly turn it up and down like it is a volume ****. But if I don't have it turned up a good amount then my subs don't pound at all. So if they say that it is not some form of volume control, then when my gain is turned down, where the hell is my bass? Where is the power from my amp? My subs don't move at all if they gain is down.

Very grey area your posting!

underpowering a sub in most cases is the direct cause of why a sub will blow.

Simply underpowering it will be ok, but when you turn it up and the available power is not there, that is where some problems can occur [img]graemlins/thumb.gif[/img]

how about
A bigger box means that the subs will play louder

a kid in kickechat came in with this one, because he'd just switched from Jensen subs and a 1200 watt jensen amp, to 2 kicker L7 12s and a KX1200 and it was louder... but it was just because the box was bigger... after all, it was just 2 12s and 1200 watts right?

(BTW I know that the box is the biggest part of SPL, but saying that the gear has nothing to do with it, and that you should build it as big as humanly possible is pretty dumb...)

Your post is even more ambiguous than mine....

Actually it makes perfect sense, what happens to an engine if you operate above red line? This is very similar to what happens to a sub when an amp runs out of clean power, it is called clipping which causes a speaker to distort (loss of control of the motion of the driver) which causes an excees heat buildup in the voice coil, which if it cannot be dissipated will cause failure of the sub. And since most people want more bass or louder spl, these are usually the people who underpower or abuse their subs.

Smaller subs are "punchier" than larger ones.

And the whole wavelength thing.

Ahhh the " 15's cant play sound Q theory "
