Ok, as some of you know, I really dont know sh1t when it comes to car sound......

Now, I am upgrading my system to a Pioneer DEH-P5750MP. My 6X6 Pioneer compression horns are being replaced by MB Quart Splits. And I have a Cadence Q4000 (4 channel) in the rear powering a Kicker 10". Oh, and I also have Compression Horn 6X9's in the rear (disconnected at the moment).

I know its been touched on before, but there has been no clear answer as to where to mount the tweeter. I'm after SQ, not huuuuuge sound. I was thinkin of mounting on the dash, on the circular bits. And also, should I use my 6X9's or leave them alone?

I'm after suggestions people, anything, ie: power the sub and splits, or use the HU for the splits, turf the 6X9's, etc, etc.

cheers, jon

i say goto mitsubishi and buy the little triangle tweeter holder thingamabobs from a VRX for 16 bucks each

nice idea, but i thought that wasnt the best place to mount them (in terms of SQ). Also, does anyone know if MB Quart splits would fit in there>?

well in terms of sound quality.... u'd need evething to be of equal distance from your ears right? well then u gotta move ya chair to the middle of the car

anyone else have any sensible ideas......

According to FHRX (i think it was) the best place for the tweeters is under the dash because that way they are both roughly the same distance from your ears. Best bet would be to pm him bout it.

KICK PANELS!!! = good sq.

The carpet area next to where your feet sit. You want your tweeters:
1 - As close to the woofer as possible. To avoid separation.
2 - As far away from the driver's ears as possible. Unlike a home audio system you cant sit in the middle of your car so you want to decrease the path difference between the two tweeters = Better stereo imaging.
3 - Symmetrical so the driver and passenger get the same stereo imaging
4 - Pointed at the listeners ears - As treble is very directional
The main reason "split" systems are designed is due to the fact that the stock location in most cars does not point directly at the driver. If it did point at the driver a coaxial speaker (tweeter in the woofer) would be much more advantageous. By having a small tweeter which is easy and versatile to mount you can mount it in a position that fires directly at the listeners ears. Which results in better stereo imaging.

So best bet is mounting in the kick panels. You would have gotten a mounting bracket with your splits for the tweeters. Just screw this into the plastic through the carpet and its installed. Or you can make a custom pod using whatever takes ur fancy. Wood, fibreglass etc...
Aim each tweeter at the opposite headrest, this stops the closer tweeter being overly bright on one side.

On the other hand if you go on the dash or up high, you will have very painful treble, right in your ears and it will appear much louder from the side closest to you. But it will look stock and neat which may be a bonus.

Ok, so mounting the tweeter as close to the woofer as possible seems the way to go....... right?
now, what to do with my 6x9's? also, is there a particular way i should be hooking up my 4channel amp? atm, its just powering my sub...... is that a waste? should i use the other 2 ch to power the splits?

ps: i dont know sh1t...

Not only as close as possible, you pretty much want all of the above, each is important for different reasons. Experiment with blutac and just mount them everywhere, they're your ears so do what sounds good.
I assume you've bridged two of the four channels into one channel to run the sub. Do you currently have two spare channels? If so, dont bother wasting these on the rears. Run your rears off the headunit. (I usually don't have them on at all, they just drag the sound behind you where you dont want it)

Use the two channels to run your fronts.

If its 50 w rms they'll love it and give you heaps of clear power. Also you'll want to High pass your fronts off the amp. This takes out the low frequencies that the front speakers struggle to reproduce. Your sub will take care of these frequencies. It will also mean your fronts can operate much louder without distortion.

You want your sub playing as low as possible. If your after sq you dont want to notice the direction of the sub. By playing it low it will appear to come from the front speakers.

Fade your rears down off the headunit if you want rear fill. But I definetly would amp your fronts over the rears.

make sense? Does ur headunit have rca outs for the front, rear and subs?

yep ive got the same ones as yours and they fit easy

or u can just get a h/u (like the alpine one i have) that u can set the time delays from each speaker and the bass focus so it doesnt sound like its in the boot

Time delay is great for the driver, but not so good for the passengers considering your throwing all their sound out. Hence the symmetry comment. But each to their own. Most people would drive by themselves anyway.

Time delay will help issues in regards to distance between speakers (path distance) but will not affect stage height, and separation issues.

yep my HU will have Dual pre-outs and Sub out....... erm, what does that mean?

Again, i state: i dont know sh1t about car sound....

therefore, can i get everything yousaid, again, but in english? sorry. i stoopid

Ok cool.
You will need to run another set of rca's from the 'front rca out' in the back of ur headunit into channel 1 and 2 of your amp appropriately (for left and right)

I'm not sure what configurations you have on your amp but for channel 1 and 2: You'll want to turn off the low pass filter, turn on the highpass filter. And set the highpass crossover as low as you can(should be a dial there for it) .
You will need to run a new set of speaker wire from your channel 1 and 2 outputs into your crossovers (the little box you got with the new speakers) positive to positive negative to negative for each crossover input. Then run a wire for the woofer from the crossover and for the tweeter from the crossover for each side.

For your sub you want the other set of rcas running from the headunits 'subwoofer out' as i imagine it already is, and this should run into channel 3 and 4 of your amp.
Then check your manual how to bridge the 3rd and 4th channels. I imagine you run one wire from the negative of channel 3 into the negative of ur sub, and then run another wire from the positive of channel 4 into the positive of your sub. Or vice versa...
Settings for the 3rd and 4th channel = low pass filter on, set the low pass crossover appropriately according to what sounds best. Lower = less volume and more deep bass. higher = more volume and more punchy bass. But as your headunit has already cut out the high frequencies for your sub out, you can also leave the high/low pass off for channel 3 and 4.


All this should be in your amp manual. there will be a spot with three speaker configuration. Check that too

so, you are saying:
keep the rear 6x9's but turn them down.
power the front splits via the amp.
and keep the other two channels powering the sub.

white? or wong?
