I've had this done for quite awhile. You can do it without taking anything out. Just pull the top push pin on the driver's side cover in the trunk. Reach for the "knob" and turn it to your liking. Definitely helps the stock radio.
It won't get too bassy but it makes a difference
Its behind the carpeted cover on the driver's side. Its mounted to a brace behind the quarter panel. Take off the push pin and reach behind the cover. You'll find it. Its a box and you'll feel the knob. Turn it one way and then the other to get where you like it.
Really only takes a matter of minutes to do. Makes a pretty decent difference
