Rear speaker question

[Cunningr]

I just bought one and it was a cabrio model. I am having trouble getting the amp out of the car though i cant seem to get a wrench properly on the top right bolt. I am going to try a cresent wrench this evening.

I am bout ready to pull the trigger for the reaer speaker kit. I put some blaupinkts in the dash which sound better but i dont like the so i have ordered some JBL GTO, initially had some infinity ref but i messed up mounting using the cia mount ring, glue messed up the neoprem i think just scarficing the oem speaker is a better solution for the dash mount.
