False floors and fans
Posted 05 Aug 2002 - 00:26
How do I go on with Ventilation?
Do I need some fans or something?

one either end, one to blow one to suck air back out.

You should find some vents (one either side) that let the air in the car escape when you slam the door.
Put fans in the rack, and use plastic tubing to duct the air in/out of these.

How do I wire them so they only come on with my stereo?

There was a v good site about relays etc. but it has disapeared. you will need 1 relay, 1 switching diode (to protect head unit) 2 fuses holders, 1 for signal from head unit and 1 for signal in.
I put all mine in a lovely little tweed box my gran nitted me (honest...or it might have been a black pastic box from Maplins)
All the parts are available from Maplins.
This is how my false floor was done...

I hope this helps.
Computer fans run at 12V but if you go down maplins, they have fans from 40mm up to 120mm.

Wire in a relay which is operated by the remote out from your head unit. This relay can also feed the amp(s). Maplins sell a suitable relay for about 50p

What parts would I need?

All you need is then a diode which stops negative voltage going back up to the head unit if you blow a fuse on the amp. The negative voltage can kill the remote turn on output.
When i get home i'll give you all the part numbers and take some pics of how i done it.

Rectifier Diode... part# QL73Q
Fuse holders... part# RC70M x 2
fuses... 1 amp part# GL74R 5 amp part# GL81C
There are 4 terminals on the bottom of the relay, labelled 85, 86, 87 and 30.
The remote turn on from head unit goes to terminal 85.
terminal 86 goes to ground
terminal 30 is power in, so from your distribution block
terminal 87 is the remote turn on output that can power all your fans etc.
The diode needs to be soldered to terminal 85 and 86, there is a little line on the diode, this should be towards terminal 85.
Remember to fuse the inputs into terminals 85 and 30, 1 amp on the 85 and the 5 amp on the 30.
It is easy to do, sounds complicated, but easy. This was the first bit of soldering i did :)
I then put mine in one of Maplins small black plastic boxes and use speaker terminals to connect the wires outside, i'll get a pic of it 2morrow for you. :)
I hope this helps

I think I still need the pic to guide me :)
