Thank you. So, channel 1 could be drivers door 10", channel 2 could be pass. door 10". Both channels at 4 ohms.
Channel 3 could be drivers door 6.5 at 4 ohms, or 2 of them at 2 ohms. Channel 4 would be the same for the pass. door. I think I got it right?
Do I need to worry about crossing over the 10's a little lower than the 6.5's without isolating them from each other? I was thinking along the lines of 70hz on the 10's and maybe 100hz or so on the 6.5's? I guess what I'm trying to ask is will they "interfere" with each other if they have different min./max crossover settings.
