Two Head Units

[Niall]

Someone correct me if I am wrong but wouldn't it be possible to connect the loom to the top one(screen unit) and then tap into this loom for the switched live and ground needed to power the lower unit (head unit + cd player) as I am under the understanding that this one will just be a slave for the screen unit and sound will go via the pre out's etc.

Thats how i'd do it, then if you start blowing fuses you'd have to look into other methods

Haha i do love how pikey some people can be with electrics!

With regards to power, i would T off of the original loom and then work out your total current draw and replace the fuse to suit providing it isnt that big a jump otherwise the wiring will have to be upped. Luckily, they normally over compensated for wire size anyway!

Dont be under the impression either that you can just mash wires together and worst case is it will blow a fuse. Not everything is fused and you can do a lot more damage than just a fuse!
