So here is a recap. I have an older insignia HU. 4 preouts no sub out. I'm going to leave front dash 4x6 hooked up to HU, then each of 4 doors is going to have a 6.5 Memphis 15-mc62, this is where I'm stumped. I'll get back to that. 2 jl trx650-csi 6x9s sealed boxes, 2 rf p3s 2ohm dvc 12s, 1 jl w3 12 4 on svc, rf t1000-1bd, jl 500/1d JX, spl gla4-1200 4 channel 500 watt rms. So the p3s are going to be wired 2 ohm to the rf 1000-1 pushing roughly 375-500 each, the jl w3 is in a HO112 wesge box running 4 ohms off the JX 500/1d pushing. Roughly 300-375 watts. The 4 6.5s are going to be set up in pairs to the front channels of the 4chan, which is stable 125 watts at 2 ohm or 100 at 4 ohm. The 6.5s are missing the cross overs, so each 6.5 has a set of terminals for the woofer then a set for the tweeter. I have bass blockers on the way to wire up. I'm having difficulty finding specs on the 6.5s. I'm not sure of the impedance. I'd prefer to have them running a 4 ohm for crisp quality, but am OK with running them at 2ohm. Should I run parallel, wires from amp to woofer, then woofer thru bass block to tweeter? That should out the speaker at 4 ohm right? Which means that each th woofer and tweeter are 8 ohm initially and parallel drops it to 4. And hooking 2 of those up parallel will drop to 2 ohms. The issue is these came with crossovers but I bought them used without them. My understanding of a crossover is that it doesn't change imoedanc, merely seperate signals so that the impedance stays the same. Am I correct in that? If so is my initial plan of hookuo going to work? Or should I run each speaker in a series between the woofer/tweeter with the bass block and then run 2 in parallel? Now that I think about it, if the crossover works as I think. Hooking a single speaker up parallel with a bass block will drop it to 2 ohm? Now I'm all confused... I've been trying to do my research. Thanks for your time, patience, and effort in resolving my issues.
