i'm probably going to hear some crap about this, but i have two audiobahn awt12x's that i had in my old car and i gotta say, they impressed me a good deal. especially for only seeing 1200 watts a piece when they're rated at 2000rms, they would pound plenty hard, and didn't sound bad at all.
now, i'm not going to say that audiobahn is good, or that you should choose them over anything else, but i can't say that i agree with all the audiobahn is crap statements you see on these boards. they're just.........not the best...by far, but believe me, you CAN do worse. my system beat quite a few, some of which i thought should be louder than mine.
take it as you will...
