blew my HD315

[cha0 10+ year member]

So I got this new like a month and a half ago. ran it on 2500 watts for about a week but i was getting killer voltage drop so i rewired it to 4 ohms. all the sudden im listening to music on the way to play ball on sunday morning and the nice pounding base turned into a slapping sound. when you push down on the cone its all scratchy, and when its turned up past like 20 on the HU it cuts out. please just reconfirm that this IS blown? so i can relist it in the BST thread as a blown HD3...

BTW i was powering it with a ORions 2500D and the gain was set with a Volt meter...

Check the coil impedance with a dmm. If it is making a scratching noise then the coil could be mis-aligned or something got into the gap. If the sub is coil was fried the sub would be locked up.

when switching to 4 ohms, u didnt crank the gain to get it to sound like it did when u had it at 1 ohm did u?

I am thinking he clipped it and blew it. That sub would not break a sweat with 2500rms on it....box tuning, box size, gain settings on hu an amp are all in question right now.

you must have had the amp in full clip. And as jmanjr said box size, tuning, and did you have the bass turned up to compensate for the 4 ohm wiring. Did you use bass boost? All of this is a factor, my guess is you had everything turned up way too much to try to get the most out of that amp at 4ohms and you clipped the hell out of your signal. I own 2 HD3 15's and I know for a fact that they can take 2500+ clean watts daily. Main words clean watts.

Let me make it kind of easy to understand if you tuned your box at 40hz and tried to play somthing around the 24-32 hz with a clipped signal that would probably rip the neck joint from the spider landing, if you tried to give it to much power in a huge box, that would blow it, if you tried to give it to much power in to small of a box or sealed that would be a problem, if you wired it at 4ohms and turned the HU setting up that would be a problem, thats why I said I am almost positive you clipped the signal and now have a blown woofer on your hands, I ran a VFL 400.1 on a single 12 and never had a problem! thats 4k for those who dont know.

If you want to sell it blown, I would be interested.

Yep, sounds like it. Tis exactly what happened with my DD 9515d and the reason why it's comin back to me with a recone (G softparts ftw //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif) I ran a soundstream xxx 6500d to it on a weak electrical. It was a dual 1.8 and one coil read 1.8 while the other read .9 ohms. When pushed down on the cone it had a lil bit of scratchiness. DD tech told me half the coil was fine but the other was severly burnt and it was because of major clipping.
