I did the retarded and wired up my DVC sub as a SVC and blew the subwoofer . How should I go about returning this sub (has a year warranty); Should I say I had it wired up in DVC parallel (amp wattage is close to sub peak) and it just blew? Say it got too cold and that ruined it? Or tell the truth that I wired it wrong and ask for a new sub? How much do stereo shops care about people returning blown subs?

Please share some info, if I can't return this sub, i'll be out $200

 

If it has a warranty shouldn't you be able to tell the truth anyway? Or is that insurance..

 

Id prob just say you wired it up fine and dont know what caused the blow.

If you wired it wrong and they know it, I dont think they will return it at all.

 

Many sub companies will warrant mechanical flaws, but not thermal failure.

The way you wired is irrelevant. It was over-excurted or overpowered. Send it in if you think you have a chance. If they find burned coils then they may choose not to warrant it.

 

If it's user error, then they most likely won't replace it. Just don't say that you did something wrong. From what i've looking at, it seems that you overpowred the single coil.

If they asked what happen, make up a story, that is reasonable. lol

One time I had to send my CDT Audio midrange in because I blew it. I bridged my amp (150x1@4ohm mono) and sent it to the speaker (rated at 50w). I only had one speaker in there at the time as I was going to finish up the second kickpanel. I didn't set the gain for the amp yet, but my dad being a nosy guy, went out and cranked the living crap out of the system, and so it blew

I called CDT Audio and told them that one of the 2 blew and I told them they were hooked up the the same amp (2 channel). Didn't tell them that I was only running one and made it seem that one was defective since the other one works fine I mean, 2 speakers on the same amp, one blew, must mean it was a defective unit right? LOL! Needless to say, I got a brand new midrange. muahahaha!

 

I blew out an eclipse sub because i wired it wrong..
But luckily i told the truth and the car audio shop was willing to replace it for free. I guess it just depends on the shop.

 

That wiring would not cause the sub to blow. Distorting, over excurting, or sending dirty, clipped power to the sub will. I'm sure you did one of the three.

 

If it is under warranty most companies will replace it without questions. More of a keep the customer happy and build a good reputation than determining what caused the problem. 80% of returns are most likely from customer abuse.

You don't owe the stereo shop any explanation other then the speaker is blown. Say you don't know. The distrubutor of the product will determine if its warrantied not the sales shop. If they have questions they will contact you or deny your claim. If they contact you then you can decide if you want to tell the truth. IMO you FU you pay. But a lot of the time manufacturers are willing to eat it knowing you FU.

 

Does the sub wtill work a little if you use the other voice coil?

Test it and make sure(if it does kill it), if you take it back to the store the may check the coils with an ohm meter and see that only one coil is bad. So make sure both coils are gone before you take it back. Just tell them it kept getting quieter and quieter and then stopped working.

 

*shakes head*
It would not matter if one coil or both coils are burnt.
That is thermal failure. There is only one way to do that to an inductor, and that is to overpower it. Trust me they will know its your fault, just send it in.

 

Most places dont care if the sub is blown because of overpowering or distortion(excessive heat) if it was hooked up right, but if the store knows the sub was not installed correctly that may be a different story. I have blown subs for the fun of it; some plugged into the wall(overpowering ) they will take them back. Some companys only offer warranty if installed by a dealer. they will know it wansn't installed by a dealer if 1 coil is fried and one is reading perfectly fine.

 

nsxxtreme, so your saying if I overpowered the other voice coil, I couldn't take it in and say the sub blew? They could tell that the sub was ran off of one voice coil even if both are burnt?

What happens to a sub if its wired up correctly and it blows then?

BTW the sub sounds like its farting, is that exactly whats wrong then, the voice coil?

Well technically the sub did blow, but like nsx said, just say you don't know what happened and that you're a newbie, thats why you got the warranty lol. If both coils were burned, then that must mean both coils were hooked up. A coil cannot burn if it is not overpowered. If you didn't hook up the second coil, no power is flowing through.

If both coils were hooked up and the coils blew, then it blew because of overpowering.

 

Okay, what are the characteristics of a blown subwoofer? I noticed on my sub that there is a 'separation' or tear between the cone and the rubber surround. its about 2 inch's wide and is on the seam. So, would the 'farting' sound be because of just this tear, and not a burnt voice coil?

I'll take my sub to work tommorow and try to test it with an Ohmmeter .

No I am saying it doesn't matter if one is blown or both are blown they will know you F#$% it up. Hooking both up does not increase the power handling of the single voice coil. So you over powered the thing plain and simple. IMO you have a better chance with one blown of convincing someone it was defective. The wires have a coating around them for insulation. It could be possible for this coating to get damaged some how and create a short which would create a lower impedence. It's a strech but best lame excuse I can think of. Just send it in and cross your fingers. I think you have about a 75% chance at getting a new on.

 

possibly it's because of the leak that is making the noise. It will make an air fart (for the lack of term) when you have a leak. Kind of like if your box isn't sealed correctly. You get a flapping noise. If the coil is blown, either you hear nothing, or you hear nasty scratching sound

 

Hmm, so would the store replace a sub with a leak in the cone? Does this make the situation better ?

 

they'll probably think it's user error, because rubber surrounds just don't rip on their own, unless u did something crazy to it. Rubber is harder to tear than foam surrounds (assuming same thickness)

 

There is a pic of what my sub looks like, and the green shows where the seam separated. The jagged black edge is just paint worn away, this isnt my sub I just edited this pic.

So, I didn't get a tear in the rubber, i did on the seam. Once again (), how do I go about returning this?

 

Return That joker Crap like that dont happen on its own can you say DEFECTIVE

 

Say the truth: not in details though

"I wired it up, turned on the stereo and blew up"

don't get in to details of how the wiring went.

These corporations won't be hurt by 200$, but you would be.

gud luk

 

Well I took the sub back. I just said the sub went, and showed them where the seam came apart and they didnt ask any questions about the wiring at all. They had to send it away to Alpine to get it either fixed, or have them send me a new one. I have to wait 4 weeks to get it back and i'll have to pay $10 for shipping.

Hopefully they just send me a new one (y).
