[QUOTE="bbeljefe, post: 8162970, member: 655960"] A ported box will do better but the sealed one you built shouldn't be causing the driver to bottom out. Even though it's large, it still provides more acoustical suspension than a ported box and that woofer is fine in a ported enclosure. So... How did you set the gain? Half way doesn't mean anything, because half way could be twice as much as it should be. Do you know the head unit's clipping level and if so, did you gain set at that level, with a scope, a DD-1 or a voltage meter? If not... see above. And as has been mentioned, are you using bass boost? If so, did you set it before you set the gain and did you turn it up more than half way? Also.... what frequency is the crossover on your amp set at? [/QUOTE]
