[QUOTE="hispls, post: 8779896, member: 614752"] Most 3" 4 layer coil woofers we use will hold up to 1000-1200W continuous. 4" 6 layer should = 4x6x100 (2400W) or somewhere in that neighborhood. Bear in mind, if you are not using top quality coils the adhesives that hold the coil together may fail before that, if that former isn't very thick you may have issues with bubbling from outgassing (this is particularly a concern with flat wire) or breaking mechanically under extreme pressure conditions. Pushing your product to failure may well reveal a weak point in your materials/design/manufacturing. Build up some subs with that coil and start testing. I'd say with a 4" 6 layer coil and stiff suspension your sub should be pretty indestructible up to 1600-1800W even buying off-the-shelf from China. [/QUOTE]
