I have a few questions about a sound system im gonna put in my car. I'm planning on using as of now is Alpine SWR 1243D, which is an Alpine type R sub 12" 4 ohms, double voice coils, with 300-600 RMS. then i wanna plug that into an Alpine MRP-500, which is a mono sub amp at 300 rms. but at 2 ohms the amp puts out 500 RMS. i know i can wire the sub parallel since its a DVC into making the amp 2 ohms, but my question is will that damage my speakers since their impedence is 4 ohms, or will it matter since i wired them parallel?
