Well........the left side of my BA stereo system are now intermittently going in and out on me. I'm in outside sales so I drive ALOT and I love my tunes! I'm thinking it is the BA amp crapping out....so it is the perfect time to get the JL XD400/4 amp and ********s 5G Fark harness. Just bought all my goodies today on line and can't wait till they get here and install them.
