How would it sound? It would sound inferior to the G5. Look into the G3 if you are already looking at the W3.That's too expensive...as far as the JL W3 would it fit and how would it sound? I can get them cheap so I considering that.
To make sure, just don't buy it from there at all. Buy it new from an authorized dealer like Crutchfield if you plan on buying online.how risky would it be to buy a G5 on craigslist? How can I make sure it hasnt been abused?
