I'm waiting on an Arc 600.4 to come in and if I install it and it isn't as clear as the JL it's going straight into the Mississippi river
The difference will be negilgable. The Arc is ruler flat clean. Proven over and over. Not quite as warm sound as JL, but pure clean sound quality all day long.
My dream amp would be a JL 4 channel amp that fits in the fairing producing 200 watts per channel without bridging. Now that amp would take me straight to audio heaven. LOL!!!
