In a bit of a debate with subwoofers right now my skar audio zvx-15 which I recently purchased has been good to me but its on a soundstream rub2500 and I'm a bit disappointing at the subwoofer because it is bottoming out on the low notes and the amplifier is not clipping. I don't understand how a 8 layer coil with a 340 oz mag could bottom out on 2.5k if its even getting 2.5k. btw box is right under 4 cubes.
Now I am also debating buying 2 12" lanzar opti 1233d's rated at 3000rms a piece and I have seen them take it. Now would this be an upgrade or a down grade in your opinions? And what are some suggestions you may have? I don't have deep pockets so upper Fi, DD, DC, blah blah blah is gonna be too much. I want to hit at least 152 db with 5k out of the trunk of a honda civic. Suggest away!
