[QUOTE="brad.farmer, post: 216245, member: 547961"] What causes a sub to blow? That is a good question. Usualy, the answer to this question is, too much power capacity is being strained on your woofer. For instance, say that you have a 1,000 Watt RMS amplifier. At volumes that are not full blast, you do not get 1,000 Watts RMS going to you subwoofer. Amplitude increases (for speakers) by wattage increasement, to the speaker. But, at full blast, you would have 1,000 Watts RMS running to you speaker. So, if your amplifier is a little strong for your subwoofer, but you can still hook it up to you sub, just don't have it on gutbusting loud. Otherwise, your voice coil, will overheat, and be destroyed. Usualy, when a sub blows, and it looks like it is in perfect condition, that means that most likely the voice coil has melted. This is due, to power capacity that your sub could not stand, because of intense heat to the voice coil. Sure, your cone and surround is okay on the sub, but way down deep inside, the voice coil has been fried. brad.farmer [/QUOTE]
