Seriously, can't expect much more than achieving a LOUDER sound. There's very little of a sound box space behind them and unless you're parked with the motor off and just want to play your stereo for the benefit of passerby's or friends....save your $$$. Just my 2 cents.
To achieve greater volume and clarity, you'll need speakers and an amplifier.
I'll suggest starting a thread in the Audio Forum on this site. Lots of knowledge there. I'll also suggest letting them know your end goals and budget, to get you started.
With that said, I went with MMAT speakers and Stinger amp. It's loud to the point that I never have it turned up high because it would be too damn loud.
Here is a difference between stock and MMATs speakers...
