If Ive got 2 12" subs in a sealed box in the boot (pointing away from the rear seats, total of 200WRMS) and I want some 6x9s in the back, is it best to have them on a parcel shelf or in the rear door cards? What im saying is; will the sound produced from the different pairs of speakers interfere with each other or not?
Wont have them (6x9s) amped so only control over them will be from the head unit, what do you lot think???
