I thought I posted this earlier, but it didn't work. I'm looking for advice on mounting my tweeters, mainly I want to know where. The stock location is way up in the corner of the dash, and the dash is literally a mile long in the new civics. I was thinking of mounting the tweeters on the door, basically in front of the side windows in the little triangle peice (basically just inside the door opposite the side mirror). Please see picture and let me know what you think.

(note that is not my car)
Another question I have was how I should mount the 6.5" drivers in the doors. I was going to try to use the stock location - but should I cut the old speaker grills out? You can kind of see one of them in the picture above - it is almost entirely covering the speaker with little holes in it.
Keep in mind for both questions that I'm going for SQ - I'd like to get the best SQ I can with the equipment I have.

Generally, you want to keep the speakers on each side as close together as possible for the best possible phase and least amount of comb filtering around the crossover point.

In reality, if you're looking to use stock locations for stealth and simplicity, I'd recommend to put the mids in the stock locations (K.I.S.S.). Then grab some two sided tape and stick those suckers wherever you would be willing to put them. Remember that aiming makes just as big a difference as placement. As you go off-axis with them, you're going to lose top-end detail. I'm having an issue with this in my truck, in fact.

I'm sure some of the other guys will have some tips as well and might know the easiest way to stick 6.5s in your doors.

Edit: BTW, the other post did work. I'll keep posting on this one.

Yeah don't cut out the grill in the door. It will look like crap if you do.

I have my tweets in the a pillar, and it has worked out well. But Jake is right too. Take some tape and play with the location ill you find something you like.

I would be mounting a new speaker grill over it. The new grill would be more open than the original. Don't you think the factory grill would destroy sound quality?

try a-pillars first off with the double-sided tape. put them at a level just above that hump on the dash, aiming them straight at each other and away from the windshield just a bit. Betcha it will sound pretty darn good.

THe A pillars have a side curtain airbag in them. I think this might effect a more permanent install. This is the reason I was going to go for the small part of the door that sticks next to the A pillar - I could eventually flush mount them.

I'll try both places and drive around with them that way for a few weeks, and see how it sounds.

Any other opinions about the 6.5" mids?

The side curtain air bags are not in the pillars, just the charge for them, and its encased in a metal housing.

It looks like a C02 cartridge.

The rest of the area under the trim should be open.

I would say angle the mids in the door, (under the panel) but your going to run into the same problem I did. Your limited on how much swing you can get out of the mid. So you can't bring the driver side on axis enough to get the outer images of the sound stage to space properly.

Bingo. I'm getting diffusion, losing top end on my mid and I can't get my tweet on axis enough so I'm losing top end there too. It's messing up the presence of vocals and instruments, not to mention imaging.

What exactly do you mean by on-axis and off-axis?

Point the tweeter directly at your head. That's on-axis.

Now slowly start turning it away from you. You're going more and more off-axis. Off-axis is measured by degrees off-axis from you. So if you move it so it's pointing directly right from you, that's 90 degrees off-axis.
