yes mate, nip the wire going to the original woofer and that becomes your input to the crossover :)

And yea, you need to get some speaker cable mate to wire between the crossover to the woofer and tweeter. I got some flat stuff they use which is pretty good, especially if you wack the wiring underneath the doors waterproof skin (the white plastic) :thumbs:

anyone?

Just started wiring in my infinity components and kind of unsure of where exactly they wire to. Do i just cut the wire that was connected to the vauxhall woofer and connect that to the crossover box input? (i take it either that or the one going to the tweeter will do because there both fill range). If so, do i just leave the spare tweeter wire in the door? Also, am i then going to have to nip to halfords and get some speaker wire to run from the crossover box to the tweeter and from the crossover box to the infinity woofer. Hope someone can help :o thanks guys
