You can check its specification to see if this is the case. If it does have a Class A bias, this means that when the amp is idling, it will still let out a considerable amount of heat.
Checking the idle power consumption is a good way to establish whether the amp should be letting out heat when it is not being used, or whether this is down to a problem that needs resolving. For example, if your amp has an idle power consumption of 60 watts, it makes sense that it would get pretty hot as a result of this.
Just imagine how hot a 60 watt light bulb would be! This video provides a thorough explanation of why amps warm up when in use. Similar to amps, preamps also tend to get warm as a result of their power consumption and output. They should also have some form of ventilation to prevent them from overheating. These units house a wide range of features and electronic components, like those I just mentioned, into the chassis.
Another factor that should be considered when trying to determine why your preamp or amplifier is getting hot, is the reputation of the manufacturer. Some amp and preamp brands are renowned for their products producing a lot of heat.
There are many online forums dedicated to the specifics of preamps and amp models, which may be worth taking a look at to see if other people who have the same item as you are also experiencing an increase in temperature when using it. Additionally, you should monitor how long it takes for the amp or preamp to become hot. Leaving any electrical device on for long periods is likely to result in an increased temperature. However, it will definitely affect the performance of the speakers in a way.
Fortunately, there are speakers available that are heat resistant. These speakers, in particular, are designed for the beach, park, or any outdoor space with direct sunlight.
Most line arrays and outdoor speakers designed these days are heat resistant. After the speakers convert the electrical signal from the amp into sound, the remaining power is dissipated into heat. However, the speakers should not get too hot to touch.
It could be one of the three possible factors we have already discussed. Also, the speakers could be faulty, and you have to repair or replace it. Subwoofers get hot when you turn the volume up too high that the signal begins to clip. They can also get hot when connected to an overpowered amp without proper amp to speaker gain matching. But when they get too hot, it means you are driving it too hard, and you need to dial things down a bit. As I explained earlier, subwoofers can also get hot when they are driven by an overpowered amp without gain matching.
And that will cause the speakers to overheat. To simply avoid this, keep the speaker volume at an acceptable level. This will prevent sunlight from heating the speaker and its components. You need to have the right amplifier for your speaker. Everywhere Threads This forum This thread. Search Advanced…. What's new New posts New media New media comments Latest activity. Search forums.

Speakers getting hot and smell Thread starter cfox10 Start date Aug 20, Forums Car Audio Discussion Subwoofers. JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding. Mar 21, 1, 0 Tillamook, Oregon. I'm running a PlanetAudio D Monoblock amp to one of my Pioneer 12" Champion Pro subwoofers in a 1.
Running one subwoofer right now, it's 2ohm and it's running with my subsonic at around 23hz, my bass boost all the way down, my low pass is at around 80 on the amp and HU, my gain is set by ear around half way..
I'm also running 2 awg power and ground. My wire in the sub box is only 16g though? Could that be why? It also isn't very loud? When I moved the setup from one trunk to another car This whole situation is messing with me. On top of all this Jun 28, 11, USA. Sounds to me like you are running that sub sealed? I dont think that sub is supposed to be ran sealed. Running ported may do so much more for you.. Hmmm, speaker heat dissipation. That is something I had not considered.
I wonder how closed back cabinets handle this. Well here is a pic of the enclosure, but with a different speaker. It is a sealed enclosure, but there is room for some air movement. I've been using the cabinets for a while, but only with 15 watt amps. The new 50 watt amp is pushing them a little or a lot harder.
Messages: Most of the power sent to the speaker is dissipated as heat. The rest is converted to sound.
