Whats the update on fan? i happened to see a huge Rexus 250mm Blue LED Clear Silent Fan (pc fan). can be placed behind amplifier by raising it and giving a blue glow all around it.
"what ideas i keep getting when i dont have anymore exams"

DO: Fans - TechEnclave

Bought cooler master PC cooling fan with 4 blue LED to match the amps led colors, and installed with 2 way sticky tape, power supply is given via remote amp powering switch, so whenevr i switch on the music fan switches on automatically and till now it's working as expected, kept is sucking mode to extract exxecive heat from amp, will post the pics in the evening.

400 bucks for the fan and used the existing wiring which was done for my subwoofers grill to rotate and glow the led's of the grill, removed the grill as it use to make hell lot of noise while pumping the woofer.

Default Cooling fan in Car Amp with pics.

First pic is without switching on the system 2nd one is after switching on. Air is getting sucked via those tiny holes ment for controlling the gain, LPF, HPF etc it can be made bigger but i don't wanted to spoil the looks of the amp.

Default Cooling fan in Car Amplifier

Right now, as the amount of hot air to be sucked from those tiny holes is negligible even with fan working on full power, the install will not be effective as desired. So, in order to suck hot air from within the amplifier and from the power transisters, you will need to make an appropriate room for the fan. The solution is to cut a circular hole and then install the fan while maintaining the glory of the amplifier while giving it more advanced look. Also, in case there's a need to make adjustments to amplifier settings, there will be no blockage. Refer to the attached picture for better understanding of the procedure.

Also the size of the fan can be reduced to fit properly. A smaller fan will provide more hot air suction from within the amplifier than even if you install a kitchen exhaust fan on top of those tiny holes.

Did this thing solved the problem or you still facing it, I would say get your amp checked by some good mechanic.

Edit: Just read your post that its working as expected, Good job.

I'd say that blowing air to the amp would be more effective than sucking the air from it!

Default Cooling fan in Car Amplifier

Blowing air to the amp will simply try to disperse off the heat off the giant sink but since its not using any cooled air, it can further cause amplifier either to have no effect on its heating or may heat it up more after an hour or so of runtime. If an arrangement can be made to draw cooler air conditioned air from the car cabin to the boot and directly over the amplifier, then it will surely work great.
Sucking the air from within the amplifier or sucking the air off the Amplifier heatsink from backside by the use of axial fans will result in the more efficient cooling when there's no cool AC air is available to blow on the amplifier. Heat energy transfers between a solid and a fluid when there is a temperature difference between the fluid and the solid, is called "convection heat transfer". More the fluid motion around the solid, the more this theory will come into work. Here the solid is amplifier power transistors and heatsink (from inside), and fluid is the air. Since this fan will suck and throw out hot air (heated by convection heat transfer) from within the amplifier, same amount of air thrown every moment will be replaced by more cooler air from somewhere ready to take off heat from the hot components (as per the convection theory) to be thrown out again by the fan. This heat will be dispersed into the boot and will be ineffective to raise ambient boot air temperature.
I hope this will clear all...
Here's another diagram made by me..

Default Re: Cooling fan in Car Amp.

if am not wrong blaupunkt amps heat up more than JBL amps or may be equal , but still they don't trip .. better find the flaw first and then add up fan ..


Adding a fan is not difficult , people who repair amps or headunits can easily fix it !

Default Re: Cooling fan in Car Amp.

Mounting the amplifier behind the seat in an inclined position can cause the motherboard to overheat. I suggest you take your amp out, mount it on a particle board but install a 12 volt computer fan, I suggest 4 inch size and place it under the amplifier with a spacer about 5 mm, make sure you test the fan to see it will "suck air to the amp otherwise the whole installation is of no use. Wire the ground wire of the fan to the amplifier's ground and wire the positive to the "remote" of the amplifier and then mount the amp in its original holes that was made to hold the amp there.

Hopefully, this should solve your issue.
