Porsche Boxster s "04" Bose Subwoofers

[2flylo]

Hi.
Was wondering if anybody out there knew if the rear Bose Horn & Subs behind seat
has there own Amp. or does it get the power from the amp under front Hood.
Ready to replace radio with Nav system & replace amp with the 5 channel Pdx-V9
Alpine. Also does anybody run Subs under the front hood on boxsters . And how
do you think they work?

Thanks for your help....
