If all the speakers are amped how would you level match? Is this even needed?
FYI, there are two amp here powering all set, Alpine PDX-4 powering front door card and underseats and PDX-5 powering rest, all L7 speakers, underseats Jehnert, boot sub JL W6 (which is powered by PDX-5 mono).
What will steps for level matching in general?
Note: I am working in stages, next step will be to install Morel Hybrids in the front door cards.
