Hi all, does anyone have a pardon kardon sub in there w251 that could measure the diameter of the speaker and the dimensions of the enclosure so I can work out if I can use the enclosure for after market speaker etc. Im toying with the idea of changing all factory to Focal K2 including centre if anyone also knows the centre mid diameter as well.

I can find part numbers but nothing says the size of sub actual woofer or centre speaker

These are 6.5" im fitting a Kicker Sub to my subwoofer box.

Got any pictures
