On a 2ohm duel voice coil subwoofer, how do I wire it to the side terminal to get the proper 2 ohms I need for my class d mono 2ohm stable amp. + to + to side terminal, - to - to side terminal and then to my amp + to + and - to -, or is that wrong. Please

Thank you for pointing out yet another thing I know absolutely nothing about.

Try using a multimetre across it, to measure resistance. Hopefully there will be a diode in the subwoofer coil and depending on which way you measure the resistance, it will be either infinite or finite... That might give you some clue how to do it.. I don't really know, though.

You can not measure the 2 ohms with a meter,as it represents the speaker's theoretical load on the amp.Good or bad ,it will measure near 0 ohms-a continuity check only.It requires sophisticated instruments to measure a speaker's impedance(the 2 ohms).Yes,hook plus to plus,etc.and you will be o.k. With a mono amp,if you hookup backwards,you will not detect a difference,because there is no spatial reference as there is with stereo

Wiring it that way will result in the blowing the sub. That way will double the voltage. 1. You need to connect + on the amp to + on one of the voice coils. 2. Connect - on amp to - on that same voice coil 3. Connect - on the second voice coil to + on that same voice coil. I know it sounds crazy but right now I have a similar setup with 2, dual voice coil Diamond Audio 10" D3's

to arrive at 2 ohm you need to take 1 cable for the amp + and - to 1 dvc sub input into +- of the sub and take + to - and - to + of the same dvc this will in turn give you 2 ohms
