i am deciding between getting 2 jl 12w3v2 and a 500/1 amp or 2 jl 12w6v2 and a 1000/1 amp for my 2000 rx 300 is the difference in price between those worth the performance and much louder/ higher quality are the w6s ??? And also would a jl cleansweep make a big difference in sound quality if i am not getting a new head unit or can my factory deck handle it?? dont know much about the cleansweep... thanks...
