Well put in my Infinity kappa 3 way 6X9's
and kappa 4X6's in the front, problem is, i dropped like 2 screws down the top of the dash, and when i take turns you can hear them floppin around, any ideas lol?

Try a magnet on a string. Drop it in about the same spot, a week later pull out the magnet. Hopefully the screws will slide past the magnet or magnet will slide past the screws and catch them.

Heh wow, that's brilliant. Yet so simple.

I did that for one screw. It drove me friggin nuts.

Interestingly, I ended up replacing my heater core about 8 months later. I found the little bugger in the process.

Took much theropy and a few drinks to regain my sanity.
