I have a 04 crossfire coupe. The rear subs are shot and busted and do not work at all. I been trying to research new 4 ohm subs for the rear with no luck so I know I will be losing some oomph by losing the subs and replacing with speakers. However these speakers have gotten great reviews. The cd unit is still stock but will replace with aftermarket unit at the same time. What do you all think? Will they work? Will they still sound good? Any suggestions or comments will greatly be appreciated by me and anyone else wondering about these speakers. Thanks
