Thats because theres nothing good to hear

my opinion go with sealed box... that is a smaller box with great sound quality

and depending on the car go with either 10s or 12s
I have 2 10" JL Audio 10w0 picked em up for 95$ a piece great deal and even better sound... ABSOLUTELY amazing sound quality

and i got a Bazooka ELA300.1 300W Mono amp from circuit city for 80$

all that with a fiberglass enclosure has my car sounding great.

Car audio is my thing so if ya need anymore help PM me
