Smell from CVX?

Question

I have a 15" Kicker CVX powered by ZX750.1 (the power certificate said it had a top output of 928 watts, the sub is rated at 1000 watts

i have run this sub for about 2 months and all of a sudden in the last week i can smell the sub when i play a rap song..(hard, constant bass.) I have not changed any settings on my amp since the smell has came except i turned the gain down a bit but that seems to be no help. I have the gain set at less than half. I know the smell because i have blown a sub before and its the smell of the copper coil burning.

However the sound quality has not changed at all, it still plays perfectly clear. I have no clue how this could be blowing because i am underpowering the sub by 100 or so watts. any ideas or answers are greatly appreciated

Answer 1

turn gain and bass boost down

Answer 2

Setting the "gain" or input sensitivity control is an important adjustment common to all amplifier installations. Proper gain setting helps reduce noise and distortion and allows for the widest possible dynamic range. (it is not "power", just matches radios volume to the amps)-   to maximize clean signal strength from your amp

Turn your amplifier's input level controls all the way down.

Put in a tape or CD or tune in a radio station. Turn up your receiver's volume control. You'll begin to hear music at faint levels. (Audiophiles and sound competitors may want to use a dedicated test disc, http://www.crutchfield.com/App/Product/G... or something with a lot of bass)

When you start hearing distortion, lower your receiver's volume control until the distortion disappears. At this point, you have as much signal as possible passing from your receiver into your amp. (This gives you maximum signal-to-noise ratio, so you'll enjoy clean sound and your system will be less prone to engine noise problems).

Now begin adjusting your amp's input gain. Turn the input level controls up until the system is as loud as you can stand it or until you begin hearing distortion — whichever comes first. If you hear distortion, decrease the gain settings slightly.

By following this procedure, you'll optimize your amp's performance at the receiver's maximum volume level, so you can crank your system almost all the way up without amplifying any distortion, or damaging your speakers. Keep in mind that this adjustment does not affect the power output of the amp — you're simply setting the amount of input signal needed for optimum sound quality from your system.

Many amplifiers have a bass boost function. In most cases, it is a variable control — you simply dial in the amount of boost you'd like to hear. Bass boost levels can range from +6dB to +18dB, depending on the amplifier. As you experiment with this adjustment, you'll notice that the boost is centered at a given frequency, so you'll still experience some bass boosting at frequencies above and below that point. Make sure that your system is turned off or operating at low volumes when you engage or turn up your bass boost control — boosting bass at high volumes can damage your speakers.

Answer 3

well, first thing is you apparently don't know what the gain on your amp is for. I'll let someone else take care of that for you as i'm sure someone can explain it better.

Answer 4

Gain should be matched to your receiver's Voltage rating, and Bass boost should be avoided as it can cause clipping (BAD).
