Subwoofer Problem?

[Rebel3190]

Me and a friend were messing around and put a Memphis 10 and a Lightning Audio 10 in a dual box and wired everything up and when we started the memphis wasnt working so we just used the Lightning ,well on my way home after a day of running it pretty hard it would still make the bass noice but wouldnt move,we ran a pioneer bridged 600watt amp,and i looked at the memphis and when i pushed the speaker in it wouldnt move at all unlike the lightning or earlier in the day i could push it in,also on the memphis it had 4 spots to hook up speaker wire but we only hooked up 2 my friends idea,anyone know whats up?

I've had speakers in the past do the exact same thing. Generally they are already damaged for some unapparent reason. Resistance inside the vc is increased to the point of voice coil lock-up. I usually do a vc inspection and they have always been burnt and unraveled from the voice coil former and sticking to the sides. This is more than likely the same problem if your cone is frozen. That is not a good sign. They will sometimes still play notes but generally will not kick on untill you crank some power to them and overcome the resistance problem if at all. Also don't use 2 different subs in a box sharing the same space. One will evenually destroy the other. May be the case here.

If it has two sets of inputs its probably a dual voice coil. I would always connect both coils. Sounds like you got a burnt coil.

And, if the woofer has 2 ohm voice coils, theres a good chance you might have blown the amp. Only powering 1 coil, you were only giving a 2ohm load to the amp, and most (a lot of) amps can't do a 2 ohm load in bridged mode.

very true you should go to a car audio place and get some advice that way you dont mess anything else up. ::
