Cancellation/Phase issues from 6 sets of mids and pair of 10"? *Pic

[monkeyleg]

Been getting alot of comments relating to the number of components in my Ford Focus. I'm in the process of building it and was wondering if there will be any audible problems resulting from all these speakers playing at once? I included a rough sketch of what the car will look like, front view.

The A pillars will have a 6.5" mid and 2 tweeters each.

The back deck above the trunk will have 2 6.5" mids firing into the back of heads.

The back seat bench will have two sealed 10"s.

Each door will have two 6.5" mids and two tweeters.

Trunk will have a ported 15"

Ceiling will have four 4" mids off deck power firing down.

Did I bite off more than I could chew? Any comments/suggestions?

I have no clue about cancellation, but I want a build log on this right now. lols, jk, but seriously.

I know I should have started a log a while ago, I think I will this week But damn this is bothering me. Someone one here HAS to explain if I'm doing anything wrong

Here's a tease, almost done door panel -

Oh and how do you embed pics?

The 10"s aren't going to be used as subs are they?

And as long as you know what you are doing then go for it by far.

Yes the 10" are subs. The Sub in the trunk will be 2' away. The waves from the trunk and the waves from the 10"s will have an audible difference when they reach the front seat? But I though a subwoofer won't tell you where the sound is coming from? Now I'm thinking...

yes, you can tell where the sound from a sub comes from. personally, i think you have way too much going on here. but some small changes i would do to your plan are, use the 10"s for killer midbass, 8 0-300hz. the 15" sub for 8 0hz and lower. loose the roof speakers. and either loose the speakers in the rear deck or make sure they are in an enclosure. the pressure from the 15" will make them sound like shit unless they are sealed.

if you are worried about phase and everything, look into a processor with time alignment.

Wow thanks for the suggestions, it's awesome to have a second opinion to steer you in a different way of thinking. I would rather keep the 10" subs and get a 3sixty to fix any issues. The 15" just isn't loud enough for me. The back deck speakers are in sealed mdf enclosures with 3 layers of fiberglass. Do you think they will screw up the overall sound? with the mids playing straight at the front windshield? And any particular reason to get rid of the roof speakers?

to embed pics with photobucket just copy the code labeled "IMG Code" for the pic and paste it in here, it's that simple for pics that don't have that code, right click the picture and select "copy image location" and click the "insert image" tool from the reply box, and paste it in there.
