I've been on this form before about the same thing, but I thought it would be more appropriate to post here. I've purchased four DC Audio Level 1 12"s. I don't a box that looked very similar to Steve Meade's "Bucket O' Bass" series. For whatever reason, one of my Subs blew. The coil is burnt up, but the other three are perfectly fine. I want to know what happened, and if it'll be covered under warranty. I doubt it'll be covered under warranty but it just seems to be a little suspicious that it was the only one that blew. Doesn't make any sense to me. Based on kirchhoff's law, shouldn't they all be taking equal current? I used Rockford Fosgate wiring wizard to make sure I wired it right. It was both me and my dad wiring it together, two set of eyes on this. I doubt we wired it wrong, wiring is super easy and my dad has done it all his life lol. I can send pictures of the sub and box. Also, the amplifier is not crazy over powered. It only has 100 extra watts per sub. Which it's always good to have Headroom. And no, I am not using the gain as a volume knob. I set my gain right. The app that I'm using is a QCA4000D, 2000w rms. I set the gain at 49v. E=√P•R E is volts, P is desired wattage, and R is resistance. I used that formula. E=√1200•2, E=√2400, E=48.989, That means, my AC output at max volume should be 48.989 (49 is fine). That's correct right? I doubt I screwed up that bad with simple gain settings. Also, if the amp is the problem, why would it only attack one subwoofer and not all of them? This doesn't make any sense... I'm kind of new to this, but this is seriously confusing me. Can anyone help?
