Use a DMM - AC Volts and measure the output voltage on the amp... if you are getting a reading of 15-35v then your subs are probably done for. The amp is doing its job. Like fatboytyler said, I feel like this is an equipment issue.

Test the battery while starting the car. The constant wire (if everything is hooked up correctly) will mirror the batteries voltage drop (if any) while the car is starting It could just be that dual headunits dont like 9v.. at that point youre just talking about internal parts and the quality...

What pickup1 said.. red (accessory) is supposed to drop to 0v when the car is started. The yellow (constant) wire should always stay 12... If your constant is dropping to 9v first thing I would do is check that your battery is in good condition (12.6v when the car is off, at least 13.8v when...

Pictures would help immensely! But, If I am imagining this correctly, all you would need to do is connect one set of wires to your sub. Positive wire to positive lead, negative wire to negative lead. And leave the other 2 wires (for the stock subs extra voice coil) unconnected.. tape them up...

What type of amplifier is it? If you are setting gain with a DMM, you should measure AC Voltage at the speaker outputs on the amp. You want to turn up the gain until you see a specific voltage. E = Square Root of (P x R) So, 500w X 2ohm, then take the square root of that.. = 31v. Turn up the...
