I will go try that right now, However I should have been more specific, I have the MRP-M500's which do not have a phase switch (unlike Alpine's MRD-M500's.) So if I do find that the amps are out of phase... how do I fix it?

I tried just running one amp with no success, I've unhook and reconnected everything and still no luck. The sub is all that's left I believe. Time to use that warranty...

To test the sub, remove the speaker wires from both amps. get a battery AA AAA C D or a 9 volt. Touch and hold the negative wire to the negative terminal of the battery. Now briefly touch the positive wire to the positive terminal of the battery. If the speaker makes a pop sound, the woofer is not your problem. This test will not determine if the speaker is blown or rattling, it will just let you know that it still makes sound.

On your drawing you only used one output from the LOC, is this the case or did you just not draw the second cable. You need to feed both inputs of both amps.

Do you have a volt meter? What kind of a vehicle are we dealing with? What color wires did you connect to the Line out converter?

I've been running a different setup off the loc for a few years now so I know I have the correct wires and i double checked the connects to make sure nothing has come loose. This setup is running in an 06 Altima.

I have a single side of the loc split to 2 signals and then run to another rca splitter on each amp to make sure both amps and both feeds are the same. I've read allot of arguments over "stereo bass" and I figured there's no harm in taking the precaution.

I picked up a dmm and played with it on my old set of type-r's to make sure I knew how to use it.

The IDQ gives me no reading on either coil. So I'm pretty certain it's a defective sub.

Is there anything else I can do? Or should I just try to exchange it. I've only heard good things about the IDQ's but I've only had the sub for a week... and it hasn't worked yet.

What did you have the meter set to when you checked the speakers? Did you use a battery to see if the speaker popped?

I did use a battery with no response from either coil and I had the meter set correctly.
