Well I must say it is not a DUD... It was working for 3 weeks. In this case it is not like it came out of the box defective... so something happened between now and then that caused it...

Your warranty at this point is with Sonic... give them a call...

Reason JL does not warranty their products if you do not buy it from an authorized dealer is because, these dealers go through the training to make sure amps are set up properly.

In this case I am not saying it was not... But simply saying this sub worked for 3 weeks, if it was a dud it would have been DOA.

It is best to run 2 subs with a combined channel, Like a MONO amp or bridge the amp. This way if there is any power fluctuation between the amps leftand right channels, subwoofers are not trying to fight each other trying to produce sound.

Questions on your system set up...

Are you running a sealed box with 2 chambers? meaning does each sub have it's own enlcosure...

I read from comments on your post you have a 2 Channel amplifier... Are you running left channel to one sub and right channel to the other sub?

If you are running a 2 channel amp, you will need a box that is divided.

If you have a box that is all one chamber, meaning there is NO divider between the subs, you will need to bridge the amp and run it to the subs bridged... Providing you have the correct impedence when you matched up your subwoofers with your amp. (this will not be possible to do unless you have the correct impedence)

Most 2 channel amps will give you XXX RMS x 2 at 4 ohms
If you bought 4 ohm subs then you are most likely stuck with what you got.
Unless your amps output bridges to 2 ohm stable. then you can take parrallel the subs and run them together...

What is the amp you are running?
