HELP! Front speakers question!

[316i compact]

I have a problem. My ti didn't have any optional items about hifi system.Not even a tape/receiver. So i builded the whole system on my own. Till now i was using simple speakers at the front, mounted at the OE position, right next to your feet, yeah, under there. As its normal sound at the front is really bad because of the bad position.
I have a set of JBLs speakers which include crossovers , tweeters and midbass.
My question is : the mid bass requires 56mm depth and 118mm diameter. Can i mount the speakers on the door panels , at the point where BMW mounted the midranges? is there enough depth behind?
And the other one about the tweeters. I could easily mount the tweeters on the door panel , at the OE mounting point. But this is not going to be the best choice and i would prefer to mount them higher , on the door plastic triangle behind the mirror, like BMW did at the TOP HI-FI system that was optional for the ti. And this is my question: Is there some space behind the plastic triangle so that i would cut it and mount the tweeters? Has anyone of you tried it?
I would apreciate any help!

Hey Niko,

You should have no prblem with the tweeter behind the mirror (triangle). Usually tweeters come with flush mount or surface mount adapters. Surface mount would be the only way to mount them there.

As for the midbass, I would recommend putting them in the OE kick panels. The staging will not be as good in the doors. I think you're mistaken about 118mm diameter. JBL only makes 100mm, 130mm and 165mm component sets. If they are 130mm, they fit perfectly in the factory location. If it's the 100mm, you will need to make a MDF adapter/bracket. The 165mm will need major modification or a custom built foot pod to house them.

Yia,

Hello m8 I am not mistaken about the diameter It's what the intructions write. the woofer is 130mm diameter,you are right , but the mounting required diameter is 118 mm! I know that the diam. is not a problem , just i dont know about the depth!
About the tweeters, unfortunately there are no surface mounts The mounts that they include require maybe 1 and a half inch depth ! And i am wondering if there is enough depth behind the triangles, towards the mirror! I could mount them very easy on the door panel, but the acoustics will not be so good! Thats why i want to install the midbass on the door panel! Because on the factory panels, i dont have enough midrange cause of the bad position! I have a sub on the back , so i dont really care to take out bass from the 5+1/3 inch fronts!

thats what you need and are your mid speakers 4inch or 3.5

Yeah i already saw that on realoem. I am just not willing to pay those money cause i already have tweeters, i am just looking a way to mount them on the triangles and look good at the same time. It is very silly that bmw didn't have as standard some tweeter mounts like the 46s.

[H3_2.1-ti]

You could flush mount the tweeters in the doors near the mirrors as this is where the OE Hi Fi location is. Once you remove the door panel you will see the marked cut-out were the factory twweter goes on the back. You will still maintain the proper staging if you place them there.

As far as the mids go, I do not recommend putting them in the door, unless you fabricate a custom door pod that would be positoned toward the front bottom corner of the door. The factory location is the best place for the mids; they are after all midbass speakers, so do not expect a huge amounts of thumping bass to come out.

HI 316, in my setup i install a 6.5 diameter speaker in the oem space, you have reason about the bad sound so i install other set of full range in the door pannel but was 4inches and install the tweeters in the other space in the door, but you need to find a speaker that not contact with the glass when it up or down, mine are alpine . So actually i have 6.5, 4.0, and tweeter in front and 5.25, 6x9, and tweeter rear and the sound is giant!!!I glad to help you.....

[m3outtanowhere]

i would take out the 6/9. I understand sound...but if u want bass, get a sub, single seperated components will always sound better. 6/9 boxes are huge and ugly. The dont belong in a car like this. My 2 cents

p.s. absolutly no disrespect FATHER.

[mischief]

i removed all my subs couse
rear has 5.5inch and it gives great bass sound
i changed all the speakers out on my car the bass is great i been asked if i had subs in the back

[FATHER]

i have the 6x9 to voice i have a dual 15 box for the bass

[m3outtanowhere]

Exactly my point. The 6/9 needs seperate boxes right? i am guessing that they are in the rear hatch area and are protruding from the interior of the car? If so, then (only in my opinion), are they out of place. In my ti i removed the hatch cover so you can see in the car. I like that look too. Lets people know that its a different kind of bimmer. Plus i also install car stereos professionally. I know that the stock holes are small but the right kind of speakers and amp combo, in almost any size hole will give you proper vocals in nearly any vehicle's configuration.

In short. All of your Vehicles sound starts at the head unit/stereo. If you plan to use amps then look into higher voltage output AND a total of 3 RCA OUTPUT. Buy a higher RMS power output 4 channel(max ouput is irrellevant)must have H.igh P.ass F.ilter. Get a good componet set with a high/low crossover for the front, amplify, and your good(connect stock mid-bass to old speaker wire that is powered just by the stereo). Rear- if moneys an issue get a standard fit 2-way(but not the cheapest ones)...amplify, good. If money no problem then get 5 1/4 component and customize fitment into rear panel (easy pm me) Amplify and you banging. If u want "real" cinematic bass then get some cheapies and a 1 CHANNEL MONO-BLOCK with a L.ow P.ass F.ilter. Exceed RMS of the subs with the amp (gives room to play) and u will never be happier for less money. Guaranteed or (your 5 minutes of life for reading) this back.

Not so short i guess. Neither is the processes. P.M. Me if any ?'s any time

[FATHER]

I PUT THE 6X9 IN TO THE REAR SIDE PANELS I CUT IT AND PUT THE SPEAKERS, BELEIVE THERE ARE SPACE TO DO THAT
