I was just looking at options for stereo upgrades and I started wondering if it's possible to cut into the dash and mount a set of speakers up top. If so, how big? I was thinking about moving my 5&frac14 component woofers up to the dash with the tweets and then moving my rear 5&times7s to the doors.

You're asking for a nightmare of work. What's wrong with the lower doors and/or kick panels?

Aftermarket kicks available for MN12s?

Yeah, kicks popped into my head. I dunno, I think it'd be nice to have the woofs in the dash to raise up the stage... but if it's really that hard I might just focus on kicks. Is there anybody who makes 'em for these or would it have to be custom?

it's the best idea

to put the speakers in the kick panels, but alas we have to make those ourselves, and you'll have to figure out what to do about that lovely parking brake they decided to use. Best option there would be the sc handbrake console.

I dont know were you are but here in texas it gets so hot I couldnt put regular speakers in the dash. How ever I did put 6 1/2 mid bass in the front doors and ran the componet up to my piller. Than after hours at the audio shop we got then to image perfect. and replaced my 5x7 with 6x9 in the back.

Sorry for the big pic havent learned how to use photo shop

Hey, that's cool... I have my component tweets on my A-pillars too but I just velcroed them to the inside so that they reflect off the windshield. I'm in NW KS and we've had some fairly hot days this summer, and I've been surprised that the adhesive on the velcro hasn't just melted. Are those some kind of custom mounts on yours, the way they seem to fit cleanly into that corner.

Anyway, here's how mine are mounted:

If you look you can see where I got expanding foam on the pillar trying to make tweeter pods to fit into the corner once-upon-a-time.

bmac and AaronJ, I don't see how either of you could have possibly gotten the imaging and staging right with so much separation between the mids and highs. Unless you're running a sophisticated DSP with completely adjustable time delays and tri-amplification, it's wrong. You'll have some wicked bad phase distortion most likely. No amount of equalization can fix bad placement.

Now that I'm done with that, lemme show you what I've done if you haven't seen it already:





The tweeters basically point at the rearview mirror on the windshield. The imaging is superb with excellent staging. Ask anybody who's listened to it. :D

Sir Will, I had no idea that was yours. I saw those in the gallery some time ago and really liked the way it looked. I had somebody cut me some pocket inserts so I could try it out. After months of having my tweets literally *setting* on my dash as a temp setup, I was kinda let down by the way they sounded in the pockets. I like my highs to be loud, clear and straight ahead; the pocket setup seemed to drop the entire stage down about 45&deg. However I do notice that, at times, my tweets seem to overshadow the woofs, which is why I inquired about moving those to the dash in the first place. I have a friend with some kenwood 4&times6s in his dash (stock location in a Lumina) and I really like the way they sound. Oh well... I'm actually really pleased with mine, but I've gotta say those pocket inserts still look pretty wicked.:cool:

The shop and I did the white nose test and I have a perfect line but remember my 6 1/2 is independent of its component. So one doesn’t affect the other. But where you have it your not getting good sound anyway because it bounces off your leg and goes down to the floorboard.

A flat line on an RTA does not good sound make. [/yoda]

Unless you're doing time-alignment, the imaging will sound hollow. You said that the 6 1/2 is independent of its component so they don't affect each other. I don't understand what you're trying to say. The rule of thumb is to keep the tweeter no farther from the mid than the diameter of the mid itself.

I won't say that you won't like the sound, but put David Navone or Richard Clark in your car and they'd tear it to shreds. Just because it's in your face doesn't make it right.

And yes, I'll concede that the sound is somewhat blocked by the legs of the driver and passenger, but that doesn't affect the imaging that much nor the staging. If the drivers are good and EQ'd right, you hardly notice. Just lean back and close your eyes and it sounds awesome. Now granted, if we had factory locations on top of the dash for some mids/highs, it would sound even better, but unless you can get them BOTH up there, you're asking for phase and spatial distortion issues.

I don't do it anymore, but I've earned several trophies over the years for sound quality in cars I've designed. I also do some pro sound setup and tuning from time to time. I know whereof I speak.

That’s cool we can compare trophies another day. The shows I go to rate how flat of a line you can make. Each mark more than 2 takes points off. So maybe things are different up there, but lets just yours rocks to you and mine rocks to me.

My set up is almost perfect according to USACi standards. But what do I know I just paid to get it perfect.

bmac, I agree with the RTA scoring stuff. What I'm saying is that I've seen several cars with a "perfect" RTA that didn't sound that good at all. I honestly have no clue how your car sounds. You could have gotten lucky, you could have an absolutely top notch install that used reflections and such to even out the time alignment and give a killer sound.

Just as there are rules, there are exceptions. The general rule is to keep the tweeter as physically close to your mid or midbass as you can. This is done so that you have to do the least amount of tweaking to get the staging and imaging where you want it. However there are many cars out there that have managed to except that rule and sound absolutely awesome.

My main purpose in commenting to begin with was to keep every yahoo and his brother from sticking tweets on his dash and wondering why it sounded like crap.

As you said, ROCK ON!

I agree with that boss. You are right about every 6 inches you move the tweeter away it goes out of phase. And id did take us >>FOREVER<< to get it right.

I hope to hear yours one day!
:D

Okay how about...

making kicks that are just big enough for like, some 4" coaxes? I could swap out my 5&frac14s for 6&frac12s and then put some 4" kicks in. Could I do that and have there still be enough clearance for the p-brake?

I’m sure you can do that if you have the $$$. I have always been scared of kick panels because of the word KICK. I’m a big guy and I could just see myself putting my foot right through them.

I made plexiglass adapters for my 6.5" mids and installed them inplace of the stock 6x8's. I mounted my Tweets on the out side of the factory grill in the top corner part of the triangle. I Had the Same Idea as Sir William but with a passenger in the passenger seat ( I have passengers quite often, My Wife) there legs would block out the highs from the tweets with them that low, where mine are mounted they are just above the passengers legs and sound great.
