I am not sure if this has been asked...i searched and didnt see anything, I was just looking on ebay and noticed the rear portion of a vibe with the integrated subwoofer. does anyone know if this will fit the 04 (probably a redundant question) but i want to know for sure, i like the way it fits better than the 04 and prior version.http://almisauto.com/images/05vibe18/47.jpg
scherry2's right - the subwoofer will fit.You'll need a different cargo area wall that is formed to fit... but everything else is there.If you are in question about mounts and whatnot - I've taken photos of the area without the plastic in place. I can't remember off the top of my head where they are on this site - but searching for reference to sub or insulation (which is what I was doing) should yield results. It's not simply plug and play... but there are a ton of references here.
