Yes it does depend on the install, but i would choose a MTX 9500 over a L7, even Steelcitysounds tested poweracoustik MOFOs against the L7s both 15s and the MOFOs got louder, looking for the video now on realmofexcursion, not saying th L7 is a bad sub, but for everyday abuse the MTX i think would beat the L7 i never had good luck with my L7s or SOLO Xs, didnt do what i wanted them to do, do get loud tho!!
