9N3 Install

[Bikerz]

Hi all

Got some quality Quartz components to install in my 9N3 Bluemorion.

Fronts are simple, MDF ring them in stock positions, tweeter and comps, hide crossover under lower dash some how (any advice?)
Rears - What do you guys do? I was going to make a box to fit in behind rear door card as there arnt any mounting points there. Good idea?
I had a DNX 8220BT to install which is fine. Can I fit a Shark fin and still get FM radio? If so anyone know part number of shark fin I need? Apparently cheap ebay copies dont have bits inside shark fin to make it work without a booster.

They will be run off amp in boot (false floor I think)

Cheers in advance

Sheldon
