I recently was robbed of some crap speakers when I moved .an insurance claim was made and I raised the price since the idiots did not write what the speakers were. Well the point is i'm looking for a whole new sub system . I've been looking into the Alpine R series 12" x 2 and the Audiobahn alumx 12" x2, which one is better? Also what amp should I get ? Both of the two types will be sold to me for about $300-$320 range .So I have about $700-$800 more to spend.I also need a new box ,I have a 1996 VW jetta what kind of box would sound best in there?Oh one important factor I have an Alpine cd head unit.
