Summary: Bought these thinking that I will need to modify something because the guide says that they will not fit in the doors of my challenger. They fit perfectly, make sure you attach the spacer that is included with the speakers. Not sure why the tech advisors say they won't fit.
Conclusion: Just put a whole set in my neon with a 4ch. They sounded okay without the amp but after I hooked em up to it they were sounding totally different. I absolute love these and would suggest these to anyone looking for high end sound at a cheaper price. The bass is low.
Conclusion: I really like the sound quality of this set of 6x9s. I would recommend them and I would buy them again in the future. I was thinking about running an amp to them to really see what they can do but I installed them in my work truck and don't want to shell out any more cash. I love JL!!!!
