need a cooling solution

[lubetek 10+ year member]

Wow today I was driving to the beach and after about 20 minutes my music cut out completely. As soon as it happened I knew one of two things happened. Blew a fuse, or over heated amps.

Pull over and all fuses checked out. both amps were BLAZING hot. let them cool down and had no problem turning them on and bumping. My directed 1500D is running at 1ohm and to be honest it usually runs pretty cool but my ORION 8004 runs WAY hot, (my Infinity speakers are 2 ohms from the factory so my sub has to work harder. It is stable at 2 ohms but man does it heat up.) It always has and I knew after building this system that it might cause a problem. I figure the Orion puts off so much heat in my trunk that the Directed amp gets even hotter and my 15" RL-p puts off some heat too.

Now my trunk is BXT'ed like a mofo and the rear deck has like two layers of Dynamat Extreme. I even have dynamat extreme between my rear tail lights and the body of the car.

I need a cooling solution asap. Any ideas welcome.

One thought I have is my rear deck. There is a hole about 5" in diameter in the metal that I'm thinking could be used as an intake to the trunk. I could cut a hole in the rear deck cover over the existing hole in the metal and install a low power large diameter fan to take air from the cabin and bring it into the trunk. My only problem would be how to exhaust the air to the outside. Maybe some sort of exhaust hole with an exhaust fan under the car? I have a huge trunk. I think I could make two exhaust fans on either side of the trunk, (to exhaust directly under the car.)

any other ideas??

Now that the weather is hitting the 100+ degree marker I'm gonna need some cooling or else my system will be in the off position lol can't have that now.

Oh my car is a 1994 Mercury Grand Marquis LS

rear deck and hole that I'm thinking I could install a fan on:

and the area of the trunk I think I could install exhaust fans in. that area on both sides of the trunk has an opening that drops down bellow the trunk floor. Put a fan down there with a port tube that would come up and bend out towards the inside trunk compartment?

how are your amps mounted right now, do you have a picture?

oh sorry, here is a pic of how they are mounted

cutting a hole in the deck and allowing the air conditioning to to blow into the trunk might be enough.

without any exhaust fans? Hmmm I can try that first but I would still install a intake fan on that hole so it would really pull cool air into the trunk.

hey did u notice a difference in output when u removed that rear deck with the speakers in it? i have basically the same car and want to see if its worth it removing rearfill + all that capet + shit

thats an old picture of my rear deck before I treated it good and proper.

As for out put? Well after I treated the rear deck to dynamat I installed the infinity speakers and cross overs (crossovers under the rear deck) I then placed that black foam mat thing back in. (its that foam mat between the metal rear deck and the rear deck cover. You can see it drapped over the rear seat in the pics.) Because that rear deck cover is a pain I decided to run a week with it out and it allows more bass into the cabin not to mention the rear speakers sound cleaner and crisper. After a week or so I decided to put the rear cover back on. In the end I prefer the stock look over looking at speakers and dynamat. It just looks finished and also for theft reasons. looking through my non tinted windows you see a stock system. I keep the face plate in my house when not in use. So to answere your question, yes it does add output to the cabin when removed and it does sound cleaner. Once I installed the rear deck cover I noticed right away that the speakers sounded a bit muffled. Two solutions I have come up with:

1. drill out the little holes in the rear deck cover so the carpet that covers each hole is gone. this would allow more sound through (cleaner sound).

2. using the speaker grills that come with the speakers CUT OUT an oval section of the rear deck cover for each speaker installed. then mount the speaker grills to make it look clean.

here is a pic after the first layer of dynamat extreme

anyone think its the sound deadening, ever since i got my edead liquid and some peal and seal, my 1500d gets flaming hot and i dont even push my subs that hard, maybe its the sound deadening and hot weather???

 

[pico 10+ year member]

it could be the sound deadner since it is an insulator. so it would keep the hot air in there. i would just cut the hole in the rear deck. that will let the hot air out as heat rises and let the cooler air from the cab in the trunk.

well sound deadning material turns vibration in to heat i belive, i could be wrong.

why dont you enclosure the amps in plexy glass with one fan forcing air in and one pulling air out. or find a water cooling system for them.

never though how soundening could be an insulator. this threads getting more interesting i might have to take the speaker grills off my trunk deck tomorrow because my speakers get cut off when turned up and amps get frickin hot
