By the way; I have a Pioneer 40 + 40 tuner/ CD with Marine 6" weatherproof door speakers and a couple of bookshelf (10" x 14" x 8") behind the seat. I am looking to replace the bookshelf units 'cause they take up too much space. Also have a Sirius w/ Direct Connect. The shame is, they now deleted all my Electro-dance channels but one. The 60's/ 70's stuff sounds decent though.
