I have a Kenwood 22 watt/ch CD-mp3 and front Infinity speakers in my 1987 420sel. Would like to replace the stock factory rear 4x6s. What are some of the best choices?

I realize that no 4x6 will have big bass, but am looking for a little more low end. Is the installation something anyone can do with just a scewdriver or does it make sense to pay for installation?

Thanks!
