Thats the kind of info I need, JC. I have been told that nothing beats cone surface area when comparing apples to apples but wasn't sure the 5X7 had the capability of the same punch due to its shape. So i guess I have a solid plan now. Passive crossovers for the C5 component speakers and active on the single C7 plus a single 12" or 13" JL shallow sub all at 4 ohms and from one amp. If I see that I need to add rears (which from what I hear is doubtful) then I can simply add to the back doors and add a small amp.Just so you are aware a 5x7 has slightly more cone area than a 6.5 and practically drops right in with gasket tape. If you go three way and you can fit it a 6x9 would have similar cone area to an 8” and be ideal for midbass. I personally like my JL C5 5x7 midbass drivers in my truck and have no desire to change them and I have Audiofrog GB60 to compare them to which cost more than twice the price.
