Sure, amplifiers can get warm, but not to the point where you cannot keep your hand on top of it. It gets very hot, up to the point that the video circuit starts to fail. An amplifier is the device that turns the low voltage signals from your source equipment into a signal with enough gain to be used to power a pair of speakers. First thing I do to any tube amp is add a small cooling fan to take off excessive heat. (I mentioned this in another thread a few weeks ago). Do all amps have tubes? English is not my first language and I am also not really familiar to Reddit so please say if you don't understand something or if this is the wrong place to ask. 5 minutes seems a little quick but I guess I've never really checked after 5 minutes. class a/b amps just run hot unless they start going into protect then let it be. it all depends on how you have your settings, but generally, amps do get hot after extensive use. A friend of mine said that "higher end" receivers all run hot. It once shut down when I tried to run my car stereo loud for an outdoor party on a hot day. In some amps, this can result in a burnt fuse. Recently I started to play a bit heavier music with lower tones with more distortion and I noticed that the back of the amp gets warm. I have changed the (standard) impedance setting of the amplifier from 8 Ohms to 4 Ohms after which the amplifier runs much cooler and without video hick-ups. I have several amplifiers that get quite hot – too hot to leave my hand on the heat sink fins for more than a few seconds. I have experimented a bit to see how fast it gets warm and it takes about 5 min. Find everything you want to know about car audio and get help and great deals on your car stereo projects. Hi, I am looking for some advice regarding my amplifier. Getting hot is what amplifiers do. Thanks for visiting. Its recently started getting really warm where I am from and I noticed that when I really push my amps they get very hot during summer days. It's definitely too uncomfortable to touch. It gets very hot, up to the point that the video circuit starts to fail. Amplifier spec sheets will often reference Continuous Power (occasionally referenced as Continuous Power Output or Continuous RMS power) and Dynamic (or Peak) Power. Also, if your amp is designed for high gain settings, it will most definitely make more noise than an amp designed to run cleaner. A small example: You have just bought the best record player in its class and combine it with excellent speakers. Run a 12volt fan on it, I did the same on my Memphis St Series amps, I live south Florida and it's hot everyday. Check your final impedence, ground, etc. By hot I mean you can barely stand to keep your hand on the amplifier back plate for any length of time. Adjust the gain and volume controls. I would say this isnt normal. JavaScript is disabled. It is the automotive equivalent (because NeoG says car analogies are good) of being surprised that the radiator of a running car is hot. Unfortunately, many amplifiers get hot during use, especially if they have any bias into Class A operation. If the dealer that installed your system is not going to help, then I would suggest called Rockford Fosgates support line and see what they have to say about it. Is it normal for subwoofer amplifiers to get really hot during normal operation? This flash is normal. What size wiring are you running? It gets warm. Class A mode gets really hot. Keep in mind that a typical multi-channel amp is only about 50-60% efficient. However it never shut down for running hot in a running car. P.S. regarding wire size, 8 gauge is fine for just the jl amp, but with both amps, 4 gauge is recommended. The amplifier is the link between the audio source (iPod, CD player, record player etc.) That's why they have those heat sinks or small fans. Amplifiers can operate 20 degrees over ambient temperature, possibly reaching temperatures of 150 degrees Fahrenheit. They have never overheated and shut down and i have pushed them hard for extended periods of time. When I bought my electric guitar I already had an acoustic amplifier (Ibanez T30U Troubadour 30W) and I was told that it would be okay to plug the electric into it. Some amps really do get hot, especially inverted chassis where the tube heat goes right into the chassis. It is a Roksan Kandy 2 and seems to be overheating when I run my Pro-jet turntable through it. The house is mostly at 20 Celcius. Radio has Low FM volume but AM is normal.
