I wanna know whats up with this. I love the way my one infinity 12.1d sounds with 400 RMS going to it. But I'm upgrading. Does the JL 13w7 have better SQ then the infinity's? And pushing the JL would be the jl 1000/1. Which would you feel more the 2 12's or the 1 13 and which would be loader? the 12's would be powered to there peak performance. It would be in the back of a 99 dodge avenger if that helps so a big trunk. both would be sealed boxs.
13W7 all the way. infinity subs are good SQ subs, but i don't think they get very loud, never used any so can't say for sure. do have a 13W7 and its plenty loud, 141dB daily driver in box tuned for SQ.
