Wow, I imagine not. It was a very tight squeeze - one I'm pretty happy with, all in all, since I did get 5 full channels of nice, independent, clean balancabe output for very little cash and even less space.


headroom meaning physical space, or you mean draw less power from it?

I think I'll see what a computer case fan or something similar can do for it, unless someone has some better suggestions for fannage. Much as I like the vent idea, I've kinda gotten no positive responses. The plastic feet on the thing (keeping it from making thermal contact at the mount point) did kinda bother me when I put it in. Having it mounted sideways probably wreaks havoc with the convection inside.

 

I cant believe so many of you ricers run subs in your trunks >:3

 

headroom as in draw the same power from more amp.

 

Well, don't think I'll be buying a bigger amp. The thing was really warm in my trunk today after 20 minutes. It just needs a fan. Will get on that, and report.

 

hell, even turning it so the fins run vertically will help a lot. natural convection doesn't go sideways you may recall.

 

But that amp is so goddamn big it's twice as tall as the trunk.

Just put some air on it and it should be fine. If you give it plenty of airflow it shouldn't overheat. If it does, then you've got bigger problems (like your amp is fucked up)

 

it'd probably be plenty cool if half of it was sticking out the top of the trunk

 

Ah, and we're back to venting. Not that I have any great ideas on it. I kinda like vents by the rollbar, but I would need exhaust, too. Maybe I should just pull the drain plugs. :-P

Any suggestions on fans? There are very few ways to mount that amp.

 

So, two things.

Three.

My deck sucks. The music would cut out on playing MP3's but not on the stereo. Then it stopped playing MP3's altogether, only making weird thumpy buzzy sounds.

So, I thought that was the issue, but no, the amp really was getting hot. I decided to try the scoop thing, and took the hose off my shopvac, put on a floor attachment and zip tied it to the roll bar. I looped it up, then put the other end in by the rollbar (tight fit) so it "blew" into the trunk. The radio didn't cut out once, but I never ran it very hard for very long, but it was super hot out so I think it's a sucsess. The previous night, driving to LA, when it was somewhat cold, the thing overheated all the time. It needs a pressure differential, I had both flaps open by the tank and it overheated many times till I turned the boost down.

Anyway, what I'm getting at is a fan in the unit will only move the hot air around. It'll help but not much. Airflow through the trunk will help shrink the boundary layer but also minimize the air temp.

Also, I really like the idea of ship's air intake scoops on a miata.

 

It does if you are cornering at over a G and hold it.

 

you're thinking of unnatural convection.

 

So why has no one designed me a scoop yet? I had to cut off the shop-vac-hose set up so I could put my roof up....
