I think I burned up a voice coil on my idv.3 10. I have a mtx 421 for power. I had this about a month and one night I was jamming hard and I noticed it starting to rattle bad. I took the sub out and tested ech voice coil, one is not working, so now I guess I voided my warrenty, I think I probably did. Guess my question is what 10 will hold up to the power, Dont get me wrong I did enjoy the id while it lasted, it was awesome for a 10 and for what little money I have tied into my system. But now I guess I'm looking again for a 10 for around 125 that will hold more power. My gain was set almost halfway, may bass setting was 3/4 and my xover was set at 1/2. Thanks for your help..
