Insert the red wires from the fan into the 12 terminal on the relay. Companies like Amazon spend millions of dollars cooling their server farms each year. Both speakers and amplifiers have an RMS power rating measured in watts. This means that the differential pressure across the amplifier will be increased and the flow will increase. The internal circuitry of Class A amps keeps a current passing through their output transistors, which also contributes to more heat. It's essential to consider your speakers' impedance when selecting an amplifier. Class AB amplifiers are efficient, so they'll not produce as much heat as a Class A amplifier. Take note of my 2 pics below. In this article, I will discuss the different ways you can keep the amp in your trunk cool.

Will it be concealed under a secret panel? Since a car's cargo area is often enclosed, it also helps to install a cooling fan to keep your amplifier from overheating. Since all of the speaker wiring will be connected to the barrier strip instead of the amps, it will be easy to make or break connections once the rack is installed.

I've been planning my install recently, and in the interest of maximum usable trunk space and overall ease of install I've been thinking of making a simple amp rack/enclosure that my sub box will then sit on top of. Most cooling fans are easy to install and run on 12 volts.
This can create a stuffy atmosphere for your car amps which is not good at all and they will eventually go into protect. An amplifier's efficiency is defined by how much electricity it needs to generate the power it's capable of sending to the speakers. I have an ARC Audio ARC1000. Route the cables from one component to another in a uniform fashion.
Many experts recommend getting an amp with a power output that is the same or 1. Since most accessory fans run on 12 volts DC, powering one is simply a matter of wiring it into the source units remote-turn-on lead so that whenever the system is turned on, the fans kick in along with the other components triggered by the lead. Don't know rpm/noise levels for those. Have you ever seen the air-conditioning systems required to keep a computer server room cool? If you want to use a single fan, simply leave one end of the rack off (the end opposite the fan) like the diagram below. Unlike Class A amplifiers, Class B amps are switched, so the output transistors are off when there is no audio signal to process. Many of these designs have cooling fins built into them to increase the total surface area and allow heat energy to dissipate into the air. Your Advisor, You can exit this chat now. The basic procedure involves constructing a wood border measuring an inch or so in height around the edge of the rack and cutting out a trim-plate that has the same size and shape as the rack. Freedom: Space is the most valuable asset when installing any system in your vehicle. I planned on removing the bottom plates and mounting the amps on an amp rack with fans blowing air into the amps. Even if amplifiers have a solid base, it's always good to use adaptor plates or place a piece of wood between the mounting points to give the amp some room to breathe. Also Perry has a couple of fan thermal controllers that are interesting. Makes stacking two amplifiers very easy and saves room.
You can do better (or worse). To line everything up as accurately as possible, put one screw in at a time. When all of the components are in place, secure them to the rack using screws; I recommend #6 1/2-inch wood screws. Class AB Amplifiers. Can't wait to see more.

The second way of keeping the switching and output devices cool is to use a heat sink in conjunction with a fan. 2) Now with the sticker side on the fan facing towards the left, screw the fan directly onto the hole you have cut out using screws in each of the four corners to secure it down. Transmission: 700R4. The main disadvantage of using a Class D amplifier is that their pulsed sound signal suffers from distortion at higher frequencies. It, in effect, monitors the temperature of the output transistors and adjusts the biasing to compensate for the change in the electrical parameters of the outputs (due to a change in temperature). Make Sure the Ground Connection Is Good and Secure. Upgrade Fee's for additional Customization. Now spray a liberal amount of adhesive on both the wood and the backside of the material; let it dry for a minute or so, until it becomes tacky to the touch. Each has its benefits and drawbacks, of course. The more accurate your drawing is, the better the finished product will be.

The power supply and output devices in your car audio amplifier appear to work like light switches, but a better analogy would be that they are like a faucet or tap.
