[QUOTE="SeanDub, post: 2952704, member: 568046"] To honestly answer the intial question: No underpowering a sub cannot blow it. Like someone else has said, what blows a sub is when people crank up the gain on the amp to try and compensate for underpowering the sub in an attempt to give it more power, which can blow the sub if done for long enough. Do raise a different concern: My thoughts exactly. A Dual 2 ohm sub can be ran at 4 and 1 A Dual 4 ohm sub can be ran at 8 and 2 A Quad 2 can be run at 8, 2, and 0.5 A Quad 1 can ran at 4, 1, and 0.25. I know there are more configurations, but the point is there is no sub that can be ran safely at 4 ohm and then 2 ohm later on. So the sub will be run at 2 or 4 depending on voice coil configuration. If it's gonna be run at 4 ohm, run it underpowered and live with it or buy a different amp. If it's gonna be run at 2 ohm, save up and buy the alt before hooking everything up. [/QUOTE]
