StreetZ Posted April 27, 2011 Report Posted April 27, 2011 (edited) I had just bought my two DC level 4s about 2-3 months ago or so and one of the two subwoofers blew. I had them running clean rated power with all new wiring and amplifier. I love DC and i hope to find a way to get my subwoofer fixed and it suprised me legitly when one of them blows just short of 2 1/2 months. Any ideas/recommendations are welcome Thanks, StreetZ Edited April 27, 2011 by StreetZ Quote ::::::STREETZ:::::: NEW BUILD COMING S☺☺N!!!

dwright27 Posted April 27, 2011 Report Posted April 27, 2011 How do you know it was clean power? Did you use a DMM to set the gains?

dwright27 Posted April 27, 2011 Report Posted April 27, 2011 Also, what's your box specs? Tuning and what you were playing? I know i could get my level 4s almost to the point of melting the coil to the former and never had a problem with them.

dwright27 Posted April 27, 2011 Report Posted April 27, 2011 yes. I did use a DMM to set the gains. I used the one i have at work...i work in mechanical maintenance So, by using a DMM, you couldn't see the wave, therefore you don't know if the signal was clean or not. Correct? Only way to know if the signal is unclipped is with a Oscilloscope. And no, you CAN'T hear clipping. Not trying to say the woofers couldn't have been defective, because rusty does build them by hand, but hats the chances of 2 subs built for the same person in the same day failing for manufacturer error?

dwright27 Posted April 27, 2011 Report Posted April 27, 2011 That is 4.5 cubes external. I'm assuming 2 12s?

CJ18 Posted April 27, 2011 Report Posted April 27, 2011 How do you know it was clean power? Did you use a DMM to set the gains? I would have to go a step further and say if you didn't use a scope to set your gains then you don't know if it was clean power or not. Quote

I would have to go a step further and say if you didn't use a scope to set your gains then you don't know if it was clean power or not. That was exactly why I asked if it was with a DMM. Kinda a trick question ... Edited April 27, 2011 by dwright27 Quote 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.
