WHY DO MY SUBS SMELL LIKE THEYRE BURNING?

you have them wired wrong and you cant wire them for 2 ohms because 2 dual 4 ohms can only go 4 or 1 ohm and your amp is 2 ohm stable so youll have to wire them to 4 ohms like option 2 in this http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=42#results you should get a bigger amp cause your amp is 300 watts at 4 ohms so the subs will be getting 150 watts each unless your using 2 of those amps and have one on each sub you can wire each sub separately to each amp to 2 ohms which you can do like option 1 in this http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=1&I=42#results
