I just bought a JL 500/1 to power my subs and I am anal and need to have matching amps. Will the JL out perform my Eclipse XA-4000? I am powering CDT gold series HD-6 front component set and Memphis M-class 6.5" rear component sets?
I do not think that a JL will out perform your XA4000. The XA4k is a solid amp and you would have to step up to US amps or Zapco in order to solidly out perform it.
