I have a 10 inch Alpine type R subwoofer that I'm going to put in my car. It is the old model the swr 1021D which has 300 watts rms. Since its dual voice coil im able to wire it up to either 1 ohm load or 4 ohms. Now my question what amp would you recommend and should i either wire it up to 1 ohm or 4 ohm? Any help appreciated.
