Sony Xplod XS-GTX1640
These speakers have a lot of thump to them unless you're looking for horrible muddled bass rumbling every body panel of your car. I put these up front in my 1990 Bronco and put the XS GTX6930's in the back and the front speakers alone made my door panels rattle and required a little soundproofing to deaden this issue. Even the knobs on the window cranks were sounding like maracas the bass was shaking them so much! Long story short, these are GREAT speakers that produce really even levels that produce amazing clear sound with excellent mid-range. And DON'T BE FOOLED, with minimal adjustments to your receiver's EQ, you can have solid bass come out of these guys. Again, not if you're only wanting to have stupid levels of bass being forced out to try and impress people at stop lights, but a great high quality level of bass that actually makes your music sound great and has some good punch to them if you want it.
