Hope you guys like it, sorry for the quality, trying out the new phone.
Comments welcome, hope i posted correctly.

Welcome to the club
nice thats where i got my amps as well, where in nsw are you??

looks good mate..

cant say im a fan of putting amps under seats.. imo there would be more heat coming from the floor heating up the amps, etc. not to mention when people get in your back seat, kicking them accidently etc.. . but each to thier own i suppose..

lol at trying out the new phone camera.. how come they never take as good pics at night as they do (sometimes) during the day


p.s welcome to the club

Yeah mate, I'm one for not putting them under seats, it's like putting them in a blanket, no cooling really at all.

i can assure you that the amp he installed will have no troubles at all with heating issues :) i do however agree with no installing amps under seats... simply because i would rage at people who kick them :P

btw, them some sexy rca cables you got :D got the same in my automobile

Yeah i realise it's bad, though with out doing a custom boot install, there isn't really anywhere else.
I live in North Manly, i drive past the yellow TJ VRX all the time that is parked outside kennards on Hardboard Rd, i know they're a member on here but can't recall the username.
I also work at JB at the mall, Car sound Co-ordinator, so if anyone ever needs anything, come see me.
I've also seen a white second gen with a black transformers logo sticker above the front wheel arch, that's about all i've spotted.

And yes, camera phone does suck, so i'll post one of my real photos.

I've never had a problem running amps under seats, have never had one overheat in that position. Hell, my amps live in carpet boxes in my boot, at least the cabin has aircon lol

You have probably seen echidna..... I had amps under front seats in my old car, used to have people kicking the RCA's used to piss me off majorly. Get a few more shots when you get a chance, and welcome to the club. Are you available to come out to the meet next Sunday? would be a good chance for you to meet everyone. See Here (http://www.aussiemagna.com/forums/showthread.php?t=60950)

To the people saying under the seat's is a bad spot... I have an amp under each seat and i have yet to see any signs of kicking. If your amps are taking damage, or getting cables knocked out, then it is because the people back there are deliberately trying.

And how can you claim they will overheat and it is a bad spot for them when they are in an area that has constant air flow as opposed to being in a sealed off boot with zero ventilation?:nuts:

How does under the seat get air flow? it gets air, but I wouldn't say a flow
And I thought passengers sort of, you know, place their feet there, amp gets in the way of the feet of said back seat passengers..

They will have no problems under the seats. This is why they make heatsinks and or in-built fans. Amps do not need flow, just ventilation.

As for kicking, I have never had any problems as most of the time there will only be people in the front. If you have kids, put them in the boot.

Hope you clean up the wires :D

Heatsinks need air movement to cool, hence why you have a fan on top of the heatsink on your computers processor, I liken it to working physically in an air conditioned office, you can still sweat like a pig because there is no movement of air, sure the air is cool but if it doesn't move, it is ineffective. Think the same of radiators, oil coolers and intercoolers.. If they didn't need air flow just 'ventilation' they wouldn't be mounted where they commonly air - in direct path of oncoming air.

/game.set.match

true to an extent, heatsinks will dissipate heat as long as ambient temperature is lower than the temperature it is cooling. this is why passive cooling exists (heatsink with no fan), in computers and electronics alike. have a look at the southbridge on your motherboard, i bet it doesnt have a fan on it.

if an amp is going to overheat under a seat, its been designed badly. car amplifiers are built to withstand the conditions that exist inside a car. if they cant do it, go back to the drawing board.

Well, you have retarded friends then if they are putting their feet right under your seat when they know an amp is there.

And there is always air circulating in a car, so it will always be getting some element of breathing space. Funny how no-one ever mentions poor circulation when people mount amp's in car boots but.

Actually, in summer my boot is cooler than the inside of my car...go figure. I reckon the holes in where the wheel well is along with the flaps that discharge air when doors are closed (which open when the cars moving for some reason) provides more than enough air to keep the boot cooler...Also, my ski-port is ALWAYS open, so whatever's in th cabin goes to the boot:D

Ha but we are not talking about making the amp "cool". It has been stated that they will not work under a front set and overheat which I have never seen happen. As woob said headsinks are their to dissipate heat. You will notice the JL amps have the black ripped edging, that is where all the heat goes. As you said ineffective yes it is, but will it work..and it will have no problems.

I have mounted the same Audison SRx2s in serveral places. Under the passenger seat, no problems, in the boot on the same box no problems, on the rear of the sub box which is pretty much sealed from the boot - overheated once and that was after 60mins full tilt on a 42 degree day and no air con. Amps are made for cars, good ones will work anywhere. Computers are made for indoors and are very moody, they are not ment to be as rugged as car components.

Your little indoor environment will have plenty of flow due to cooling for OH&S reasons. A car does not have OH&S and often gets to 60 and 70 deg sitting locked up on a summers day. Open up the windows and it will drop to ambient temp and you will notice your amp will still plug away.

Oh Nick, you're so clever, will you have my babies?


Oh you! I told you not to bring this out into the open you sly dog you.

I'm not arguing about whether or not we're cooling the amp to a mild 24 degree's but you have to admit, the whole damn reason for passive COOLING, see there, the word COOLING, is to reduce the temperature, not chill or freeze, but the reduce temperature. Read your amplifiers manual, it will state that it utilities PASSIVE COOLING.. or active if it uses fans.

My main reason for not mounting amps under seats is:

A) They're on carpet, which is warm, not terribly cuddly in a car but insulates well.
B) Under a seat which does not allow for convection, yeah, like an oven. The mosfet transistors in the amps are only rather small but they're screwed and glued (with heatpaste) to the fins on your amp and without some sort of airflow will not cool terribly well and if the air temp is the same as the temp on the fins it's gonna make those suckers go sizzle and take half your circuit board with it.

I know people have put them there and they may run fine but I am on the against team. Also go ask your TV repair man or anyone else that regularly replaces modern electrolytic capacitors what the 3 main causes of death are. No wait, I'll tell you.

1) Age
2) Heat
3) World peace..

No 1 & 2 are easy but 3, well.. We'll get to that another day. Anyway, All I was aiming for was a bit of cautious thought as to mounting your expensive amps somewhere which isn't ideal in all the locations in your car that there is. Hot air rises guys and it only gets about ten mill before it starts heating your chair and creating a less cooling environment for those fets and the fets start cooking those caps and eventually they bulge and burst buuuuuuuuut it's your money :)

Your turn, Mr Bond.

Oh you! I told you not to bring this out into the open you sly dog you.

Hmmm I do have a rather bad memory, is it your turn to bend over or mine?

Hot air rises guys

I think you just answered your own question their. Reduce the cooling is good, but amps happily run at 50deg or more anyways. My Audisons which get VERY hot don't use their fans till 55deg and will run until 85-90deg then shut down. As I said most cars will only get to 60deg in summer and when you open the windows and / or turn the air con on, down she goes.

Since hot air rises, that will mean the ambient temp under the seat will be cooler to start with :D:D:D Don't worry, I'm not saying under seat mounting is ideal, it's just with limited options in cars, it is ok to put them their - espically speaker amps which aren't as powerful or run as hot as Subwoofer amps.

We still on for dinner on Monday night?

yeah i have both my amps mounted under the seats but are V-power amps so they have fan forced cooling as well.

And yes, camera phone does suck, so i'll post one of my real photos.

Great photo.

have my cabin speaker amps under front seats.... never had a problem with feet or cooling.

i find if you dont mount the amp so the rca's are facing said feet, they never get touched. So maybe you need to turn your amp.:nuts:

ive also found that some cars have a vent that comes out for the rear passenger footwell. so mounting the amp right infront of of a cooling duct workss great! lol

How do you find the 9887? I'm thinking of upgrading my 9857 (model a year older).
