Blown sub fixable?

[MOTU 10+ year member]

I have an infinity reference 1230. The other day it completely cut out...no sound at all. Opened up the trunk and took it out of the box. There was no smell at all and no visible damage. I know it isn't the amp because I tested it on a friend's working amp. Now I know it isn't exactly high end but I'm a poor student and can't exactly afford to go out and get anything even half as good as this one is. Just wondering I anyone had an idea what the problem might be and if it's repairable.

Thanks.

You would smell it.

Alright, then any ideas what the problem is?

Check all wires, every wire !

I have, from the RCAs from the deck all the way back to the amp and speaker wire to the subs. I tested an old speaker with the amp speaker wires and it worked, so I'm pretty sure it's the sub.

Infinity subs aer not meant to take abuse.

There not made for SPL, there SQ woofers.

I have 2 10" ref's, just so you dont think im lying

I was actually underpowering it. It's rated at 300 W RMS 1000W Max (not like max matters) I was only giving it about 200 W RMS.

Clipping //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

It wasn't clipping, it was just underpowered.

 

[supa_c 5,000+ posts]

if it was underpowered it wouldnt blow

If it was clipped it would blow, under powered or over powered

 

[MOTU 10+ year member]

ok so it was clipping (even though I'm sure it wasn't) that still doesn't answer my original question. Do you have any idea what the problem is and is it repairable?

ok, so how have you narrowed this down, you tried the sub with a friends amp and it didnt work either? did you try your friends amp with your setup to see if it worked? do you have another sub that you could test with your current amp in your car? If the have the parts/time just try to narrow down your options. If the sub doesnt work, its blown.

Stick a DMM on the voice coils and see what it reads. If it's a little under the subs nominal impedence, then it isn't the voice coil. Next, check the tinsel leads, see if they are disconnected anywhere or cut anywhere.
