Hi all, I was looking at a set of two 6 inch subs to mount under my rear shelf. (Well not for me but for someone else). Its for theie mk4 golf. They do not want to loose any boot space but want to add some more bass to their car. They already have a set of components in the front and the back which give out some nice mid and treble. Firstly i was wondering if the subs would use the boot well or if i would be better off putting a box around each sub (joined onto the shelf). Also would i be better off sticking to the subs or buying a set of normal midrang/bass speakers which you get with a set of components and running pure bass out of them?? Obviously a seperate amp will be used for these subs. Also has anyone ever used 6 inch subs and does anyone know of any places which sell good 6 inch subs? Any info would be appreciated. Thanks.
