ok guys i got this idea and i wonder what you think.....actually i already started but i havent finished yet........
i bought 3/4" clear vinyl tube to run from my a/c (already tapped in to "floor") all the way to the back, and branched off into 2 smaller tubes. i plan on drilling 2 small holes somewhere under the wire cover on my punch amp and feed COLD air onto circuit board. (bd1500 @ 1 ohm with protection pulled out, and it does get a little warm.) i ran the a/c for 30 minutes and no condensation in the tube (see thru). so as long as no water from condensation i should be ok right? does anyone have an opinion on this idea? i know ill have to drill an exaust on the other side.....
i just want a "stealthy" way to cool my amp and dont really want to run fan racks if i can get around it. has this been done b4?

im with ya......we all got our brands. and i agree, every kid in town that buys an RFZ gets 2 TEAM fosgate stickers,.......and they always make it to the rear wing windows (left and right) IM oldskool (31) so "the punch" still means something to me even if those DD, Shocker, Beyond Audio, etc look real NICE.
ill leave all that fosgate **** in my honda, it pounds........my new project is my 2001 tahoe...wife already gave me permission to buy some beat for it.
I dont know about the a/c thing, something keeps telling me that eventually condensation will seep out?? I dunno for sure tho...........

Don't put the air directly on the board...cold air on the heat sink will be more than enough to keep it cool...without invading the circuitry

that would be my concern, would the AC in back all wetness to get on the boards, but AC is know to remove vapor from the air

It's an interesting idea, but going back to my thermodynamics knowledge, the little that I have left, I'd think just a regular fan would be as effective if not more. The cooling fins on the heat sink are there for a reason. High flow "warm" air will do more good than medium to low flow cool air. Unless you plan on just cranking your AC. Again, interesting idea, but I think it may be more trouble than it's worth when a little fan may do the same thing.

You would need a way to disconnect the tubing from your AC ducts when you use your heater, otherwise you end up blowing HOT air on your amps.... which is obviously not the best idea.

well hot air from a car is probably still cooler than the 140 degrees an amp gets

thats why i used the "floor"section only. i never use it anyway.
and the reason i dont want to use fans is because i wanted to try something different. amp doesnt seem to get that hot when weather is cool out so i guess id only go to this if it is over 100 out and my a/c is on anyways.

the use the ref. plates in coolers and mainframe computer here they can't any vibrations from the fans.

I'd be more worried about the condensation after the fact. If you blow cold air over the circuitry and then shut it off, the stuff that wasn't ever that hot in the first place will now be cooler than the surrounding air and the warm moist air will cause condensation on those parts. A little heat is good for an amp. I'm afraid without any feedback circuitry, you'd actually run the amp too cold. You'd also need a way for the hose to drain because, again, condensation would form in the tube when you shut the system off. Overall, it's good thinking, as long as it stay only a mental exercise.

i hear that.....condensation has been the only thing that ive been worried about.....
i let it run for 30+minutes when i first started this and i didnt get any moisture of any kind.....not even fog in the tube. oh well........if anything ill probably build an enlosed amp rack and cool them with that rather than the circuit board......like i said its just an idea that is in early stages, and i appreciate intelligent responses like yours and a couple others here. thnx.

I think it's a cool idea and also a very good your creative thinking. I think maybe if you design an elbow with a drain that connects to your A/C drain tube and keep the coupled tube from the rear deck on maybe a 20 deg. angle, you should be fine. This way any REAL condensation will roll back down the tube and out the drain port.
The other idea (and this related only to your level of due diligence) would be to make sure that you cycle the FAN only after running the A/C system to this new 'system' or pipe network. This way, you'd dry all the moisture off the amps/rack and you wouldn't get that mildew stuff attaching itself to your heatsinks.
I thought about doing a similar project where I used the floor vent option on an Integra to vent the A/C up the back of the driver's seat. I find that the damn seat gets hot no matta how cool the cabin is.... lol.
If you do go through with this, I would be very interested in seeing some detailed pics. I agree with your statement made about challenging those who are giving you put-downs. Go for it and be strong....

OK here goes you don't have to worry about condensation from the A/C its cold dry air. in the paint booth in our shop our tempature humidity control automaticly turns on the A/C when the humidty gets high. NO MATTER WHAT TEMPATURE IT IS ( even if its 0 in there) then it kicks the heater on to bring it back up. the cold air from the tube won't cuase condensation. condensation is when a cold object collects moisture from the warm moist air around it. like a glass with ice in it. so as the earlier post read the only problem would be after you turn the car off.
two things about that first the A/C duct won't keep your amp below the air temp in your car. and the air (especially inside) would be just as cold if it did( such as running the A/C with the amp off.
so..... YOU should be good to go. do it (don't expect it to cool much though) 10 degrees most i would think.

bummer i started this project on the LAST hot day of the summer here in sacramento. I havent touched it since!!! it is half done LOL.....just like some of the projects in the house (my new doors (trim not done yet) my new driveway addition(dug out but not poured yet) etc.
ill get back at it when that wild hair grows back......

No prob, Any more questions just ask. i love to see people getting involved in car audio. especially people who like to get hands on and do it themselves. ( even if it means less work for us.)

HEY MAN I HAVE YOUR SOLUTION, FIRST OF ALL THE CIRCUIT BOARD IS NOT THE COMPONET THAT GETTS HOT IT IS THE MOSFETS AND THEY ARE ATACHED DIRECTLY TO THE HEAT SINC. SO THAT IS WHAT YOU NEED TO COOL. DO YOU KNOW HOW YOUR COMPUTER IS COOLED? WELL IF NOT IT IS CALLED A PELTIER COOLING PLATE. THERE IS 100% NO CONDENCATION AND WOULD BE THE MOST EFFECTIVE WAY TO COOL YOUR AMPLIFIER. WE HAVE SUCCEEDED IN KEAPING A HIGH POWERED AMPLIFIER AT ABOUT 45 DEG. YOUR IDEA IS GOOD AND INVENTIVE BUT IM AFRAID YOU ARE GOING TO KILL YOUR AMP. IF YOU HAVE ANY QUESTIONS, I AM A STORE OWNER I BROOKINGS, SD (TRUE AUDIO CONCEPTS AND SPEED). E-MAIL US AT trueadio@brookings.net OR GIVE US A CALL ATT (605)-692-7737. ASK FOR JERRY OR JOSH.
