Hey guys I just received 2 Alpine Type R SWR-12D4 subwoofers as a birthday present from the girlfriend, was wondering what amp would power them both to their maximum potential ? And what would be the best way to do it ? 2 amps or 1 really powerful amp? Any suggestions? Both have an output of 1000W RMS. These subwoofers will be paired up to my stock headunit for now as well as stock speakers in my Civic Si. Also would these 2 subwoofers be too powerful for the car itself? Anything I would need to do beforehand? I appreciate all the help guys thanks!
