Sup all?

Well, i got my system installed today and well, lets just say that damn its hot here. My amp overheated a couple times (110+ outside). So i thought about making an amp rack back there with fans to cool the amp.

Does anyone have any blueprints or any ideas with dimensions taht you think would be nice. Im not looking to make this the best looking box. I might even put a plexi glass top on it.

Also, another note, i have a 92 325i and they had to cut out the metal where the armrest was. I think it looks ragged with the red edges. Anyone think that if i was to create a custom port there it would sound any better or worse?

Thanks. Any input is appreciated.

where did you put the amp? your description was kinda vague. the key to proper amp placement is air flow. when i put mine in i was going to put it inside the trunk on top of the inside there, so it can have all of the air underneath to breath nicely. im sure a fan cooled amp rack would not be hard tho. just be tricky hiding them, thats the nice thing about car audio tho, your possibilities are endless.

Most audio shops should sell the proper fans. We sell two sizes for 10 or 20 bucks. As far as where to mount, just make sure there is space on either side of the fan to allow it to suck and blow properly. Ideally you would have the fan aimed at your amps heat sinks as this would help the amp dissapate heat, but most times, we mount it below the amp to keep the fan out of sight. Either way, depending on where you have your amp, and what is above and below it, may have more of an effect on heat dissapation than adding a fan.

Did you use a fan on your box? I was concerned about overheating my amp, but your's looks to be in a tighter spot than mine.

Well, i actually havent made it yet. I am creating the design of it today during work, if i ever figure out which type of cooling method is more efficient.

I have seen a couple designs. I am just wondering what would be the most efficient for cooling.

Here are some designs i have been contemplating (look at attachment):

Amp1 = This would have 2 fans on top.

Amp2 = 2 fans, 1 exhuast port

Amp3 = 2 Fans, 1 Push, 1 Pull


Thanks again for all your input.

I think Prez was directing that comment at me, and No, I didn't. I haven't run into any problems, and the beauty of buying good amps, is that you can wait for it to overheat a few times and use that as an indicator of the need to add a fan.

I had that happen in my 5er, and once I added a couple of small fans, they never shut down again. I wish I would have taken pics of that install, it was bad ass.

epistemology: It's not really rocket science, or in your case knowledge science-LOL. Any of those configs would work. Really a fan is an afterthought, it just has to be well placed and functional. Design a great amp rack for your particular application, and use those skematics as a guideline on how to utilize proper fan placement.

yeah, well, I've got another box coming up in a few days, if not tonight. The actual sub enclosures are done, but I ran out of sealant and the frame still needs to be made.

Its going in a Jeep. Pretty tight design. I'm going for a look which won't hint at subs at all. The hardest part is matching the carpet, but he likes the roll I have, even though its darker. pics soon.

As for fans, don't know enough about them to say which is better.
