wiring/fitting splits

[blackers10]

reason for mounting in the A pillar is coz thats where my factory ones are and it seems to work niceley!(it has the premium setup from the factory)

and where the factory wires run for the tweeter and mid in the factory setup
and if they have an actual crossover or just a capacitor thing

how would i mount the PS2... would u just use like a metal strap over it screwed in place ..im thinkin glove box would be a good idea
or even under the passenger seat as there is alot of space under there..

cheers guys
