[QUOTE="hispls, post: 8398626, member: 614752"] Running a woofer with an amp which can make 4000W does not mean that sub is necessarily seeing anywhere near that. The zv4 coil is good, but not magical. 2500W is the power used by the largest element on an electric stove glowing cherry red. You really think a 3" coil will hold that much heat for long? I repeat my challenge, go ahead and clamp 2500W sine wave at 50hz to one of those Z coils and let me know how that goes for you. Likely you can gain from simply turning the box around firing into the trunk. Give that a shot and see if you don't notice more/better output. A new box may or may not help. IMO the specs on that box you have aren't terrible so it's hard telling whether you would really gain audibly from dumping 250$ into a custom box provided you keep the same tuning. I visited Sundown in Troutman and at the new location, had lunch with the guys there and specifically had a discussion about power handling ratings with Jacob. Unless you're telling me he lied to my face then I'm telling you the woofers he sells are honestly rated. This is the same way Eminence (the largest speaker manufacturer in the USA) rates their drivers; the ratings are clamped 50hz sine wave for 8 hours... or basically indestructible at that power ratings, which IMO is the only way to be really honest. Once you exceed these thermal limits and heat is building up faster than it can be dissipated you get into failure very quickly and exponentially faster as you increase power beyond that. Do you really think that because a woofer can take 6000W tone for 3 seconds that it would survive that for 3 minutes? If it would survive 6KW for 15 seconds, 2000W for 1 minute, 1500W for 3 minutes, or 900W for 3 hours which is the honest power rating? Just because your buddy knows a guy on youtube that runs a 3500W rated amp to a Z does not mean that sub is seeing even half that power ever. Nor does it mean that the next guy couldn't hook the same sub up to a 3500W rated amp and wind up with a situation where the sub actually sees over 3000W and fails in his first Young Jeezy song he tries to play. I think you people really have no idea what power is, how it is measured, what those numbers really mean, or how a loudspeaker works. [/QUOTE]
