Excellent... i have some spare mdf spacers that were in the other car (18 months of use, and never screwed them in, just chucked the magnet thru the stock 6" hole
So i'm thinking chuck those under for a nice flat surface to have the speaker against, and then just pump it thru the stock 6" holes. Im not planning on doing anything to my system sub\amp wise for some time. I am howver planning on getting a set of Pioneer TS-C1653's, Link
, professionally installed at purchase decemberish.
Its all falling into place now.
