What Did I Do to My Sub??

[Master0fPuppets 10+ year member]

I have a Kicker CompVR 2Ohm DVC that I ran for about 4 months hooked up incorrectly.

I think with the setup I was running only one voice coil at 500RMS at 2 Ohms.

I ran it with a Kenwood KAC-9102D 500 watts RMS x 1 at 4 ohms (850RMSx1 @ 2Ohm) amplifier.

 

It hit pretty hard. Until it started blowing fuses in the amp and got to the point where it would cause the amp to go into protection mode at anything over 10% volume.

 

I reinstalled it, this time making it a 4 Ohm load and the bass hits much softer and not as clear, but works. I don't know if I'm just getting used to the distortion, but it seems like its starting to sound better.

 

What did I do? Blow a voice coil?

you had it wired at 1 ohm = dead amp //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

edit; if the amps still working turn the gains up a lil and you should be good to go,

mebbe?

how bout setting the gain with a dmm?

edit, looking at your drawing again looks like you only had 1 coil wired = 2 ohms = maybe you did fry a coil?

test both coils seperately.

Thanks for the response. The amp seems to work pretty well now with it wired to 4 Ohms.

I blew both fuses 2x, and then the amp started to protect itself by shutting off.

I'm a novice when it comes to this stuff. Is that what it was wired too? Looking at the diagram I figures I had just wired 1 VC at 2 ohm sending 850 RMS to a coil made to handle 200 RMS max. Leaving the other VC completely out of the loop.

How do I test each separately?

If you only had one voice coil hooked up, you had 850rms going to that one coil, and I don't think that amp is 1ohm stable, which you need to find out.

Either send it 500rms @ 4ohm, or find out if that amp is stable and run it at 1ohm (or find a 1ohm amp, or get another sub)

Your best bet would be trading for a 4ohm DVC of the same kind if that amp isn't 1ohm stable

I don;t know what a DMM is, or how to use it. I had the gains set by ear, pretty much at 90-95% with 10-20% Bass Boost. But I though I was running both voice coils at 4 Ohms.

That is pretty creative //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Out of all the reviews I've read on this amp, the only negative ones where from people who ran the amp at 1 Ohm. It's not 1 Ohm stable. That's why I meant to hook the woofer up at a 4 Ohm load, but I messed up. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

I'm considering purchasing a 4 ohm DVC woofer because the amps are much more expensive, and I think its fine just the woofers broken.

Perhaps 5 minuts to make the whole post. I had to stop halfway threw and get food out of the microwave:toast:

Come back and ask your questions when your done. //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

way to kill your sub. you don't just hook up one coil. shoulda used a wiring wizard for the ohm load you wanted lemme see if i can find it...

Oh god...//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Make sure you have it hooked up to a 4ohm load right now (check rockford fosgates (sp?) site, they have nice wiring diagrams), set gains correctly (there's a how-to thread in the amp section), use no bass boost, and then see how you like it.

If its still not enough, then you'll have to get an amp, or (what I'd do) put it up for trade for a dual 4 version of the same sub
