Hey fellas i have a 2001 740IL with DSP and sports pack. just wanted to know if any one else has removed there rear deck speakers to use the trunk as a ported box? I plan on installing an JL 10w6v2 High output box and a JL 500/1 amp. audio guy says trunk is super sealed and to hear it in the cabin i would need to remove the rear deck speackers. Has anyone done or heard of this? Aslo he said he needs to bypass them amp and is chargin me 450 for a rockford fossgate digital power capictor and installation, is this reasonable? do i actually need a power capicitor. any help or insight into this would be really appreciated.

Thanks in advance Robert
