How To Prevent Car Speakers From Blowing Up

If you are new to the car audio world the most important concern is taking care of your newly installed high end expensive speakers. Many people seem to blow out their car speakers due to incorrect knowledge of how to operate them. All cheap or expensive sounding car speakers contain a voice coil, this is the wire that is placed into the middle area of the magnet that is wrapped around a pole. When current is passed through this from the car amplifier, it makes the cone forced to move upwards and downwards producing audible sound to be heard. Now how much power a voice can take is built up of many factors including how thick the wire is and the quality of copper that is used. Today you will learn about how to prevent your car speakers from blowing up and damaging them. This will hopefully increase the durability of your car speakers and make them last longer.

Don't overpower your car speakers. Sending too much power from the car amp to the voice coil can burn it out instantly. Voice coils are always tested to find out what power they can take, that is why manufacturers list the maximum wattage in the specifications section in the user manual. Now when you are finding a car amplifier you want to match the rms. Never go by peak power ratings they are just used to help sell the products and is really meaningless information. For example, if you have four car speakers rated at 150 watts rms, then you want a 4 channel amp that can provide 4x150 watts. Also just to want inform you that under powering never damages your speakers that is a myth. If you think about is, when the speakers are not in use they are being underpowered really bad then, since the cone is not moving at all, since there is 0 watts going to it. If you put it like that then the speakers are being underpowered all the time, when they are in their box and not being used when shipping. Seriously, i am not sure who came up with this false assumption in car audio but it certainly isn't true since its a proven fact, it’s just many don’t know fully about it and the logic behind it.

Set the gain right on your car amp. Don't treat it as some kind of volume knob because its used to match the RCA voltage provided by the stereo. You need to correctly tune the gain control so that there is no distortion heard when almost maximising the volume on the car CD player. You can use your ear, a multimeter or the steve meade SMD distortion detector tool to prevent distortion being heard. This is because the signal is not clean pushing the voice coil to its thermal limits damaging it from overheating.

Dont use bass boost with the volume up too loud. Now car speakers are not really designed for big bass, thats why subwoofers are installed into the trunk. You want to turn down the bass boost to the minimum level on your front and rear car speakers. This is because its creates higher distortion levels and clipping which again can blow out your car speakers in the long term. Also try not to play your music loud all the time because each time you do the mechanical parts such as the spider and rubber surround have to work more harder.
