P508 speaker replacement 

Sedan or SW is the same. This is model 2011

I think its a standard 6 inch speaker. Again not sure

@@maxfelemban it's a 6.75" or a 17.1cm

Thank you for confirming.

Just found the JVC box. It's a CS-J1720X. 165mm with a depth of 44mm. That's actually too thick, so I think 40mm is the maximum allowed (hence the filling need)

@@blaap Ahh, its undersized then. The correct size for that hole is the 17.1cm/6.5". It obviously fit but its slightly undersized. No biggie, it worked. :)

What are 'trip tools'?

I guess it's JBL

@@Johney.g tq. Whats the model?

CS-J1720X
