problem with Diamond Audio D312

well this sub rocked.. i love it, but now i got a problem... it doesnt work.i tested the amp with a friends sub and his sub works on my amp, but my sub doesnt do anything..if i push on the cone lightly it acts like it wants to actually work, but as soon as i release the little bit of pressure, it just looks at me... :crap: do you think the cone separated from the motor?? guess i gotta find a new sub to work with my amp. my amp is a cerwin vega xl600.1, which has performed flawlessly for me

why not get a real sub that can handle the power...lets say a Rockford Fosgate...

well this time i will. i am looking at RE subs and Powerbass subs
