i dunno wat this heat wave is like for you guys down south, but up here near the qld border, it has been in the 40's alot, and with my amp running in the boot (1000W) it tends to generate alot of heat, and it dosnt help if the car has been out in the sun all day, and when my amp heats up it shuts itself off b4 it blows up, so i had to do sumthing... I pulled out my draw of gizmos and gadgets i dont use anymore, and got an old CPU cooling fan from my computer and stuck it on a lil metal bracket and mounted it so it blows air straight onto the amp. by doing this it cooled the amp DRAMATICALLY, if u cool one part of the steel, it reduces the temp of the whole surface...all computer fans run on 12v so u can run it off the amps power supply with no dramas....heres a pic

my sub is in a box, and ive nicknamed it a free roaming box.... it likes to slide around in the boot, hehe...wats the easiest way to mount it, cause under the carpet in the boot its metal and my spare tyre...

i might try that myself. cuz i got 2 1000w. but generally i just put up with no music when it gets too hot.
as far as securing the box, just bolt it down, or do wat ive done, and wedge the bitch between the parcel shelf and the floor.lol

It those boss amps they have really poor power circits and internal amps so they get hot really hot but as always you get what ya pay for .

LoW GLi · « **Reply #3 on:** Mar 1, 2004, 06:56PM »

either way it still does the job.....it only over heats in the summer thou, never have troubles in cooler weather..

one of my mates was trying to convice me that BOSE was a dody brand! he was thinking of BOSS.

one of my amps (US audio, i got it for very cheep) seems to get rather hot copared to my other one so i might try a fan, ta LoW GLi.

lol at the fans.... if anybody has any cooling probs with amps and shit.. i think kyrios trx would be in the know.. seeing as though his computer fan is the size of a bloody jet turbine...

but if it does the job then sweet...

my new setup has both amps under the front seats, when it get hot i put the aircon through the foot vents. works brilliant

actually my boss amp does the job quite well running 2x 12 inch subs. i figured the boot of my car would get very hot thats why my amp has a fan installed inside the amp. keep it very cool. nice vents coming out the top to let the heat out

noss · « **Reply #9 on:** Mar 11, 2004, 10:59PM »

failing his you could superglue a wrx vent to your amp

Barnett · « **Reply #10 on:** Mar 12, 2004, 06:07PM »

mate no offence.....get a new amp.......my mate has had 2 of them blow up on him only to get re-paired and prolly blow up again

but yeah........with my box i got a bit of alloy 90 degree angle and screwed it to the sub box at the front and then up to the metal behind the back seats then a few support bits of wood just to keep the box level and she dont go anywhere

when i get my puter back i will have to put photos up of all the shit i have done on my car in the last month.

i havnt had any probs with my BOSS, ive had it for jsut over 12 months now.... no problems wat so ever....i know the older model BOSS amps had troubles, but i havnt come across anyone that has hte new chrome version thats has had any troubles..

KNG P1N · « **Reply #12 on:** Mar 15, 2004, 09:13AM »

my boss amp works fine, over a year old.yet i say nemore

wb131988 · « **Reply #13 on:** Feb 9, 2005, 10:36PM »

Does anyone know why my fan, connected to the positive and ground on my amp, turns on even when the ignition is off???

LoW GLi · « **Reply #14 on:** Feb 10, 2005, 08:13AM »

its cause its connected to constant power, wat u need to do is run it from the accessories power on the back of the head unit, this way when the head unit is off, so is the fan, problem solved........ alot of stuffing around thou! but well worth it in the end

wb131988 · « **Reply #15 on:** Feb 11, 2005, 11:56PM »

Couldnt I just put a switch in the way ive done it and turn the switch on when i want? I'm sure thats easier to do. Thanks for the help.

*~*PriNCeSS*~* · « **Reply #16 on:** Feb 13, 2005, 05:41PM »

sounds like a good idea thanks dude

Marty · « **Reply #17 on:** Feb 13, 2005, 10:23PM »

yeh i got the exact same amp and have had no problems with the temp or the unit itself
but then again i dont play a lot of doof doof,

LoW GLi · « **Reply #18 on:** Feb 14, 2005, 10:47PM »

the reason why i got the fan for mine is not cause of me cranking the amp, jsut the summer heat got to the amp, and made it like a fucking boiler room in my boot, so playing any simple music for like 1 song would make it shut off

wb131988 · « **Reply #19 on:** Feb 21, 2005, 05:37AM »

I just put a switch in between the two fans which is alot easier, so that they can be manually turned on wen the amps have been on for a while.

LoW GLi · « **Reply #20 on:** Feb 22, 2005, 08:16AM »

nice job, should get sum pics up

wb131988 · « **Reply #21 on:** Feb 23, 2005, 03:53AM »

Will do soon loW GLI. Just need to find my damn digital camera

Should be uploaded onto here anytime this week so keep your eyes open

There is nothing wrong with BOSS amps, they are arguably poor build quality, as many seem to have problems.
Problems that arise from people thinking they are 1000w, so the amps get overworked and the poor power supply fails.
They are better then just using headunit.
Dont try to make your 2x86watt amp try to do the impossible.

Sticky · « **Reply #23 on:** Apr 4, 2005, 09:54PM »

exactly aylesy, people cant seem to get their heads around the fact that its 1000W PEAK, which usually is divided by a 1/4 to get the rough estimate of rms of the amp, but BOSS amps are totally different, its more like 1/6 the peak, if not more, also the fact that BOSS amps run hotter than most at a normal load

Why not run it off the remote wire for the amp? It only has power when the amp is on.

omad · « **Reply #25 on:** Jun 2, 2005, 07:45PM »

Heh, pretty funny stuff

Seriously, though... some amps like my crossfire one that I'm selling recommends using fans if the amp is not well ventilated etc. Though the best place for them usually is blowing ACROSS the amp, not directly onto it. You also usually get better cooling mounting your amp vertically, not horizontally as in the picture.

Food for thought, anyway

Milford · « **Reply #26 on:** Jun 2, 2005, 07:58PM »

or you could put up a front mount amp

LoW GLi · « **Reply #27 on:** Jun 2, 2005, 09:19PM »

it wouldnt make much difference where u put the fan, as long as its blowing air onto the metal of the amp, it will cool just as much... as i aid b4, when u cool one part of most metals, excl aluminium and a few others, its reduces the temp of the whoel surface averaged out...

trxmad · « **Reply #28 on:** Jun 3, 2005, 01:57AM »

i think the idea is getting good air flow across the vents/metal..

Most amplifiers have aluminium or similare alloy heatsinks.

Exactly right. If the fan is mounted to the side of the amp, it's able to blow air over the whole surface (or close enough to) of the amp.
