Lets talk about Amp Cooling 🥶

Like the title states, I want to talk about external amp cooling. During a recent post about "Snobby unhelpful Dikheads" a conversation about amp cooling was sparked and I feel it was left unfinished. So I'm going to try and re-light the candle. Maybe some one can share their wealth of knowledge on how they keep their amps cool for long runs. Maybe some pictures of their amp racks with cooling, or ideas would be nice.

Quick back story about a recent trip to Vegas from LA. Took the fam on our summer getaway to Vegas for the 4th. 4 hours there, 6 hours back. I have 4 amps in my setup behind the rear seats of my Accord on an amp wall. Trunk is filled with luggage and a sealed sub. Packed, and over 100° the whole way there with no ventilation back there. Blasting music non stop just kidding Maybe like 75% before my "full tilt" mark. On the way there I lost my front sub amp (Salt 400.2) about 3 hours in. On the way back lost the salt around the same time, 3 hours in. What sux is that the car has to be shut off for it to reset itself. I'm not stopping I want to get home. Around 4-5 hours in I lost my M6, that drives my centre 2 way and bridged to my midbasses. After it cooled down it turned it self back on. M4dsp was hot when I got home but didn't give any issues only tweeters n mids on that amp and the MMATS LSX4000.1 didnt even feel warm (not surprised). So, now I'm looking for external amp cooling. Maybe that wasn't a Quick back story.

Goal is to have an array of cooling fans and not make it look ghetto, or like this ⬇. Apologies if that's yours. 😉

I have an itchy Amazon finger and have purchased a few things already. "I have issues".

The fan is really big though, I'm not quite sure how I'm going to proceed yet. I've only bought 1 Fan so far I think I'm going to get some smaller ones too just to compare and contrast. Then I'll proceed with the champion. I want to be able to piggy back off of an amp ground and remote wire. Even though I got high level inputs into my M4DSP (it has a high level sensing turn on) I still had a remote wire ran and just in case I want to run optical in, even have an optical wire ran to my centre console. I'm guessing black on the 4 pin is ground and the other 3 wires are different speeds. 🤔 maybe. I don't know yet I'll experiment. Also got a relay to run multiple fans hopefully it works.

I will be spacing all the amps off the rack a little bit (some one suggested that in that snobby post). I was on the Gatley Audio site and found this ⬇.


Now I'm thinking of mounting the Salt upside down, heat sink spaced off of the rack with the bigger fan attacked to the amp, maybe pushing air in or pulling hot air out. 🤔 like this⬇

But that will only work for the salt amp. I got those mounting brakets to mount fans on the sides of the amps and try to push air throght the internal components of the amps. Maybe I'm over thinking this and there's an easier solution. But that's why I'm here trying to spark some conversation and maybe get some ideas from other builds. Hopefully I can even get some snobby remarks from some very knowledgeable individuals. Im in no rush to get this done as im not planning on any long desert runs any time soon but I would like to be prepared for the next one. Thanx in advance if you partake in this journey of mine to keep things cool 😎. Much love ✌🤘🤟🤪

I can see few ways to mount them in OPs car.
NOT really my job to tell the OP exactly where to mount the fans in his car, though certianly I would be happy to if I had experience with the same make and model.
Wouldn't the installation of the fans be a concern, especially in this case?

How will air be exchanged in the "amp space" ? I agree that a push/pull arrangement using 2 axial fans mounted under the speaker cutouts will do a great job of exchanging the air between the cabin and trunk but the priority is to get cool air into the amps.
I hope by getting the trunk cool I can exchange cool/heat from the amp space and the trunk. I was also thinking of some smaller fans pulling heat from the amps. Just a thought. I'm in no rush but just a thought.

I may just get a few more of those. But credit is due to some one else. I don't quite remember who pointed those out ....

LOL...

LOL...

Ha lol it was you. Their nice though, when you put that like up I automatically bought it.
what would be super cool.... if you could/or wanted to..... figure out how to add some temp sensors on your amps and take some temperature measurement before and after you have your fan setup installed.... or just with fan/cooling setup on/off or something too see how well the cooling setup works.

you could also learn at what temp the internal temp sensor decide to turn off your amplifier. which would be cool/interesting for the community to know. :geek:

Lol That would be cool but my first amp didn't start giving issues for after around 3 hours of driving through 100°+ desert with a trunk packed with luggage. That's the first time I had any issues with this set up since it's been in the car. Had my install done in February. No plans of taking an other trip like that till December for the wives birthday. Even then it won't be as hot and less luggage cuz its just me n her on those trips. 🤷🏽‍♂️

Maybe just one fan in the "amp space" would do the trick, just make sure it is a Centrifugal. :)

What direction does the MMATs amp blow air out of it?

Not to resurrect an old thread but I’m surprised no one mentioned using a thermoelectric peltier cooler. Or even create their own cooling setup using the thermoelectric generator.
Why to do this?

BtDt - messy, ugly, hard to control, fan noise... inefficient (using 300 Watts to dissipate 250 Watts of heat more than doubled the idle current) and if you incorporate liquid to move the fan noise and keep your aesthetic clean then you've got leaks and/or flow restrictions to deal with... just not worth the squeeze right now.

Some people build a wall of awesome subs, Slave2myXJ builds a wall of peltier coolers to cool off his beater-with-a-heater w/o putting money into it... :unsure::ROFLMAO:(n)

I think peltier systems were mentioned. I think they where deemed unnecessary for the situation.

I have yet to do anything about this. Haven't had any issues since that last trip to Vagas. But summer is coming up and my wife is planning something that may require a long drive. So maybe I'll have to revisit this soon.
Has anyone mentioned the sparked innovations Fannie yet? Literally made to help cool amps. I don't have time to read 6 pages when a fan is the answer to these problems

Yes the answer should be just a fan. I have no air flow back there. I think just adding a fan to exhaust any trapped heat will be enough for them long desert summer runs.

4 hours of play time In 100°+ weather with a trunk full of luggage before having any issues is really not that bad. But I'd like to avoid it next time.

For peltier system, condensation/water might also be a concern? I am tempted to try this out. My system is completely buried underneath the trunk board in storage foams. Running only 2 fans right now.

Honestly I don't know. 🤷🏽‍♂️ I didn't look into it. Do your fans exhaust the warm out of the amps air space?

If it's nicely designed and durable sometimes it's worth the investment. I mean you could.be one of those guys running dryer vent boosters in order to cool your amps.
A thermoelectric peltier cooler doesn’t use liquid nor does it use 300w. Here is one: Dual-core Thermoelectric Peltier Cooling System Semiconductor Refrigeration Cooler Kit with Power for Plate Cooling Pet Bed Cooling etc Amazon.com: Dual-core Thermoelectric Peltier Cooling System Semiconductor Refrigeration Cooler Kit with Power for Plate Cooling Pet Bed Cooling etc : Electronics
All you do is move the heat from one side of the plate to the other you still have to dissipate that thermal energy in some way. Attaching a water block to the hot side and pumping that to a heat exchanger with fans is simply one way. We attached 6 x 50 Watt Peltier devices to a SALT 6k and then used water blocks with ferrofluid to a PC Radiator with fans that pushed cold air from the AC thru them... noisy and complicated and not effective enough to dissipate anywhere near enough thermal energy to be worth the effort.
