As far as i know there are no after market speakers that will fit without light modifications on the housing.
The Kickers will also need modification on the housing. And they are not designed for free air use.
I've bought a pair of Earthquake SWS 6.5.
SWS The Original Shallow Woofer
The pro on them is that they are designed for free air usage and the sound much better than the original subs. The go a little bit lower and they don't have that "boom boom character" that most try to compensate with the capacitor solution.
The con is that the mounting diameter is 6 mm wider than the original mounting hole, so you have to modify it. And that they have only a efficiency of 77 dB. So they need a little bit more power than the stock amp has – even if you bridge the 4 x 22 watt to 2 x 44 watt for the subs – which is possible without a problem.
