Been reading a lot on the forums for a good system for my wife and I. I'm leaning towards fairing and lowers for us with a 4 channel amp. Can't decide whether to go with J&M roller xx's for both with the tweeter grills, or polk Audi 651mm for both. Price wise won't be much of a difference once you factor in the adapters, speaker boxes and grills needed for the polks. Also torn between J&M 500w 4 channel or soundstreams Pn4.520. The soundstreams is exceptionally cheaper, but I'm not sure on the wiring required to make it work versus J&M plug n play system. Any feedback or suggestions is greatly appreciated.
