Mounting AMP's In a vr commodore

[Rhys-VR]

Hey Guys

Im setting up a system and i got a VR Sedan and i got a baby on the way so i put the sub in custom box oppisite the spare wheel but where can i mount the amp and wires out of the way of the pram any ideas??

Cheers guys

Could you by any chance put a pic up of your boot with box?

Cheers, Darc

i dont have a camera at the moment, its just a box what sits on other side of the boot opisite side of the spare wheel and ive stapled the wiring behind it to keep it tidy and then ive got all my leads behind the carpet at the moment becuase dont know where to mount the amp

can i mount it to the parcel shelf? or ?

[DmanVT]

how big is the box? could just mount it on the side/ back of the box?

And some amps don't like being mounted upside down due to heat transfer but i've seen it done before.

can i mount it to the parcel shelf? or ?

Yes, however I would not recommend you hang it upside down, the heat dispersion is ruined and you may end up damaging the amp.

[Rhys-VR]

ok so i wont do that so where could i mount it?

cheers

Thats what i was meaning by saying don't like it due to heat transfer :P haha

And you could make your own panel out of mdf? Mount it across back? On the side or back of the box? What room are you wanting to remain empty? centre? one side? back?

[Rhys-VR]

where the gas tank goes and the boot area i would like empty WOULD lol and i cant mount it on the back not enough room behind the box between the box and the quarter panel so i really dont know where to put it and cant put it on the back of the seat becuase wires will get caught on the pram and ripped out so im stumped

[DmanVT]

Maybe make up a mdf panel behind the seat to mount the amp, Then make a small box say 300 x 30 x 30 or something that mounts to the mdf panel, for the wires to go down behind,

Depends how crafty you want to get and what equipment you have

Please elaborate? Heatsinks are not directional

[DmanVT]

mmm :/

I wasn't sure, i've heard of people damaging amps from being upside down and then the manufacturer claims it was due to them being upside down and wont cover warranty :S but then again maybe they were just saying it so they didn't have to pay for it.

I have no idea to be honest :S

[Rhys-VR]

now im confussed lol this amp i got at the moment i wanna throw out and get a mono block its a cheap old shitter to be honest lol so i might just mount it upside down on the parcel shelf but how do i do that? and where is a good spot on the right side to mount it where the boot hinge wont hit it when mounted?

[DmanVT]

i haven't ever mounted anything on the parcel shelf before and haven't ever seen a vr shelf haha so i can't really help you but i know i've said this too much but maybe make a square out of wood and screw that to the shelf then your amp to the wood?

And if you get a monoblock maybe get a class D, Might as well go a good monoblock if your gunna go one

[Rhys-VR]

i might try a box and mount the box on the right wheel well in the boot

The PCB/components are mounted to the base of the heatsink. Heat rises. If you have it mounted upside down, the heat stays within the components rather than dissipating upwards into the heatsink.
I may be wrong, but it is basic physics and I don't see why it wouldn't be applicable here.

Here is a quick diagram from my old setup in my VY:

i have mounted under parcel shelf and had no problems. would i do it agan, no i wouldnt

[Rhys-VR]

so i think its just to make up a box and box up the right side of my boot for sub and amp and then just carpet it and make it look like its just the boot and hide it all away would be the best way to do it

[DmanVT]

sounds like it, there are plenty of ways to go about it, like how you said or a cradle off parcel shelf etc. I'm sure you'll work something out

[Rhys-VR]

yea might just mount it underneath over the next few days and see how i go

cheers for the help

[DmanVT]

No worries mate, hope it all goes well and i didn't really help haha

Cheers, Darcy

Mines under the parcel shelf and been there for about 6 or 7 years and no probs. Only a cheap amp too. Pic is in my ride pride thread.

[Rhys-VR]

not of the amp mate only the box bro can you provide pic of the amp and details on how yourve mounted it

cheers

The parcel shelf is made of metal, so wouldn't you think that the heat would rise and contact with the underside of the parcel shelf, essentially dispersing the heat across the entire parcel shelf, making it one giant heatsink?
.. Probably not considering the amount of heat a regular amplifier will produce
But I ran 3 amplifiers under my parcel shelf, upside down, for two years without a single problem.

If you are worried, do as MAG00 has done, its a great idea and will still leave you with plenty of boot space.

so bit of board down first mount that to it and then amp to the wood? or amp straight to the shelf?

[DmanVT]

id say amp to wood, i think it would make it easier? but i dunno
