Hey thats a great write up and appreciated, i know I'm a few years late on seeing but just got a boxster and replaced the 4 ch it came with a 6 ch from a 996 and installed a customer rear speaker box.
Only issue is i got a very cheap Coupe amp and the rears are not as load as the front channels and Cabrio amps are getting harder and dearer to find.

Could i do the same thing to increase the rears only or do all 6 by replacing the resistors ! thinking its worth a go as i got the amp for £35 so no real loss.
do the resitors need to match the watts of the unit ? which is 40watt output ?

From reading posts i believe porsche used lower values own the coupe amp vs the cabrio.

thank again for the write up.
