i'll bet getting BLAUPUNKT subs for the behind the seat harness, and the 6 1/2 inch dont exactly fit, they are a bit too small ( the stocks/harness are 6 3/4) but if u get them at crutchfield, they give u a ring to make them fit for free, and i saw some very nice blupunkts on sale from 60 or something for just 40$(for a set of 2), and blaupunkt is, maybe besides jbl, the best speaker manufacturer out there.
