Came to the forum to get help with adding a subwoofer /amp to a system with the JL C5 components running off a JL A4300. I'm wondering what power range should I be looking at. The sats are running 45 to 70 wts. I'm thinking the JL W3 or W1 with either the JX250 or Jx500 in ported enclosure. Going into a Subaru Forester rear cargo area. Any good recommendations?
