I installed 2 sets along with a pair of Rockford Fosgate 10" shallow mount subs onto the rear shelf area(similar to how the M-Audio subs are mounted). They are all connected to the stock DSP amp. I left the factory mids in place as well. Well worth the $450 I spent. I know you can buy better speakers components to install but IMO it will be a marginal improvement over the SC50s.
