both me and my gf have Audiobahn, and are quite happy with them.
I used to have 2 JL 10w4's (had em for years), but they got stolen...when I went to buy new ****....well the Audiobahn was teh best bump for the buck to me. I ended up getting a single 12 and a 500 watt lanzar amp to push it...for what we paid...we are both happy, oh yeah she got a single 10 and an 800 watt lanzar to push it....between us both we spent less than $500 for all of that....
