blown speakers?
ok i dunno too much about audio stuff but ill describe as best i can. I have MB Quart DSD 216 components and cross overs, pushed by a phoenix gold XS4300 4 chan. amp. (4x75 @ 2 ohms). For some reason both my 6.5s got messed up.. I dont think theyre technically blown, but like i said i dunno too much. but one of the small wires that connect from the terminal part into the base of the cone one of them on each speaker has disconnected at the very thin part at the base of the cone. I hope you guys are following me 
but does anyone have a clue why it would be doing this? Someone told me my crossovers are sending too much bass to the speakers.. I wanna solve this before i install new speakers so they dont blow. Also I have mb quarts in the rear speakers too but theyre fine.

Re: blown speakers? (m0neynh0s)
Post some pictures of this disconnected wire you speak of.
Does the speaker sound like its making a farting noise? If it is, then they are blown, but I seriously doubt those MB's would get blown by a 50x4 amp (its probably 50x4 at 4 ohm, 75 x 4 at 2 ohm... but that is a rough guess). Or are you running the amp bridged (4 channels bridged into 2) into the components? In that case, you would be pushing 150 watts to each speaker which could possibly blow them.
Have you tried to reconnect the disconnected wire? It sounds like the wire might of been gettin too much current and essentially melted itself apart as a safety precaution to protect the cone of hte speaker.
And if you think its the xovers sending too much bass to the midranges, make sure your amp isn't set on low pass filter... Make it set on all pass or flat and if that doesn't do it then try just setting the amp to high pass.
Hope this helps, but post a picture if you can. Maybe that will clear up some confusion as to what you are speaking of.
And just some clarifications for hte rest of yall... Speakers have a certain impedepence associated with them, usually 2 ohm, 4 ohm (most of hte time), or 8 ohm. Each impedence has a different wattage the amp will send out to it. The lower the impedence, the greater the wattage the amp will deliver to it. But the lower you go on impedence the more work the amp does and if you go too low (like to 1 ohm), most amps will become unstable and will overheat. But just about every amp out there can handle loads of 2 ohm or greater, so he should have no problems in that area since those MB's are 4 ohm.
