Wiring multiple midrange
Hey guys,
Long time lurker, but not a noob to the scene by any means. If you were at any of the large southern ontario shows, you have probably seen my Santa Fe.
On to the question. I am looking for the best way to wire up my new setup, be it parrallel, series, or a combination of both. I am adding more speakers to the rear and the front. Basically the front is going to have 4 6.5" Coaxials and 2 1" tweeters, the rear cargo area has 2 12" subs (not worried about the wiring for those, they are running in parrallel now) with 4 6.5" Coaxials in the same speaker boxes, and another 2 6.5" coaxials that are being glassed into the liftgate. Currently all of the highs (4 6.5", 2 front and 2 rear) are run off of a single 4 channel amp.

And if I wanted to set it for SQ?
What I have drawn out is the 2 speakers in the door are wired in parallel making them 2 ohm. The tricky part is the rear. I have (this is wired per channel so 6 6.5" speakers in total) the 2 6.5" in the cargo area are wired in series within the box, and the one in the liftgate is in parallel to the original.
My calculation puts this setup as 2.6 Ohm
ZT = ((ZA+ZB)*ZC)/((ZA+ZB)+ZC)
or
2.6* = ((4+4)*4)/((4+4)+4)

generally when you are going for sq you don't wan't multiple drivers playing the same frequencies. That's why most people going for SQ just have a 2-way or 3-way front stage with no rear fill (some people like rear fill some don't, but I'm not getting into that). When you have multiple drivers playing the same thing it messes up your staging/imaging and causes problems with phasing. If you are just trying to make it louder this won't be as much as a concern, but if you're really going for sq these are things that will cause you big problems.

Previous response nailed it. Imaging/phasing/staging will all be huge issues that you'll find almost impossible to correct. You could still make the car sound fairly tonal if you do a good job, it just depends what you expect out of the finished project.

Not entering SQ or SPL, just wanted some nice presentation with above average sound. Staging will be a pain the ***, I know, trying to balance out 6 rear and 4 fronts. Main reason for so many in the rear is for when the liftgate is open at shows, parties, meets, whatever, that the sound is not blocked and confined to just the opening.

if you really want good sq you could have all the rear speakers wired seperately with a toggle switch that you would only use when you have the liftgate open. However, in my old car I had just a 3-way front and 4 tens in the hatch and I would just open the hatch and doors.....it worked really well.
