^^ good point. the rockford 360 is great but a bit of an over kill in the smart. u can do wonders with them, but i use them for factory systems with 8 or more speakers. it all depends on what u want out of the system. for a smart i would not recommend that. they way things are now a days, i like cheap and easy. for the do it yourself person, bass blockers are a perfect fit. the 360 is kinda hard to integrate into a system.
