This is my first post on this site and my apologies if this is in the wrong spot, but I am a new member. I am replacing my cassette player in my vehicle, finally, and my subwoofer is dry-rotted. I removed the subwoofer box. BAVSOUND no longer makes easy plug and play systems for guys like me that do not want to rewire the car. Does anyone know of some pop-in audio ideas for the subwoofer and amp that would be an upgrade? The old subwoofer is a 2x2 Ohm, 2x50W speaker. Thank you everyone. I have a 2000, BMW Z3, 2.3L Convertible with 24,600 Miles.
