Hey! I just bought my brother a new sub for his car. I got him a Polk DB1240DVC. It's rated at 360 watts RMS. I'm looking at a Rockford Fosgate Prime R500-1 amp to power it with, but I'm not sure if 500 watts would be too much power. We are going to run it in parallel at 2 ohms. Would this amp be OK on his sub? Does anybody have any other suggestions? Thanks in advance!
