6x9 speakers with a nice base sound wanted

I am going to run a pair of Boson Acoustics 6x9's in my rear deck connected to a 60x2 amp. I don't listen to a lot of bass heavy music, but I like a good solid bottom end. These are the speakers I bought

BA 6x9

I picked up a good used 60x4 channel amp for $100.

The key is to good bass response is having PLENTY of power. Pushing even the most expensive speakers with a head unit alone will end up causing distortion and damaging the speakers.
