I'm interested in a subwoofer for my 2001 civic. I don't need ghetto bass, but I do want some good tight lowend music. I see crutchfied has discounts on a 12" Infinity for , box and Blaupunkt amp for 0 totalling under 0. What do you think? http://www.crutchfield.com/S-YoRJOkh7aII/cgi-bin/prodview.asp?i=1081240W&s=0&cc=01 http://www.crutchfield.com/S-YoRJOkh7aII/cgi-bin/prodview.asp?i=023PCA1300&s=0&cc=01 Any recommendations and experiences greatly appreciated.
