how do you take the rear seat out of a '91 318i? help plz!
-
um, you just grab the bottom lip in the front and pull up on both sides (driver and passenger) of the bottom part of the seat. they just pop up and then snap down, like 2 seconds to do. then to get the back part out you just take the bolts out (one on each side) of the metal brackets (you just uncovered these by removing the bottom piece, they are in the corners). once the bolts are out you just pul up about 1-2 inches and she's free! basically you pull up unbolt 2 bolts and pull up again. i could do it in a pitt crew it's so fast!

haha thanks...is there a ski pass behind the rear seat?
-

What do you want a link for? You can use a mallet or a swift stamp with your foot to punch the perforated panel out. That's what I have always done.

i want a link to how you mount our sub in the skihole... and would a 10" sub work?

Are you trying to mount the sub without an enclosure? I'm not the extreme audiophile but you'd have to select a sub that can handle the volume of the trunk if you want to go that way. Any audio site or shop can help you calculate that. As for a specific write-up, ask Zoso to make one, he's the King of DIY :cool:

It can be done:

That one is a 12" sub.
Look at my writeup for my stereo install. It's in the forums.

haha ok...i have a box right now...if I check out my thread in member's rides...i wanna put it in without the box...but if I can the the box then I might as well do it right?
I either wanna go throught the ski pass or port my rear deck...which should I do? nd i'm not going to take out my rear speakers...the sub isn't that great

For a cheaper sub with not such great power, I say put the sub in a box. You'll get the most punch this way. I went with the ski hole because I didn't want to sacrifice that much trunk space to a setup and I expected to use a 12" sub with a decent power source. I'm sure the bass could be a lot deeper if I did all the measurements and put it in a box, but all I wanted was a little more low freq response from my audiobooks...er... music (:)) so the free air 12" is plenty for me. It'll get my car booming if I want but if I wanted to be the ultimate homey, I would have boxed them so I could shake my car apart and deafen myself.
-
well, see, i have a box right now, but it seems small...it's a 10" sub with a 300w amp... would punching the ski pass out let anymore bass through to my car? or i turned the sub around and faced it throught the ski pass into the cabin? i listen to rock and alternative... so i'm not looking to be the ultimate "homey" either lol
-
I am not an extreme audiophile but for my bass needs I have 1 10" woofers that are in a sealed box that I take out of the car as is needed.
As for subwoofer position, trial and error is your friend. I have mine facing the trunk and prefer it that way. I have a punched out ski pass as well
-
k well, i think i'm gonna go ahead and punch it out... does it help pull the bass through to the cabin?
-
which two bolts is it that will let the back part of the seat come out?
-
Bottom part: Tug firmly at the corners
Top part: There are 2 10mm or so nuts at the extreme left and extreme right lower corners. There thread through some metal "arms" which attach the seat to the body of the car.
Once you get the bottom part out, you'll see the 2 nutts.

i got it thanks, and i got the ski pass out, and realigned the sub, and put the seat back in... it helped some... but not a major change...

... and put the seat back in... it helped some... but not a major change...
The seat back is what muffles the sound a whole lot due to obvious reasons :p Try taking your rear speakers out, see if that's noticably different? That could mean you making a port to help get bass in.
True audiophiles do all sortsa calculations and can do some nifty shit with setups for cars like ours. If you're on a budget, ehhh just deal with this for now :D
-
yea true that.... haha... i wanna port my rear deck just to help it come through.. i tried taking out the rear speakers... didn't help any... mostly due to the fact that i have my nicer speakers in the rear... i wanna do a port behind each speaker to let more bass in.... problem is.. will it work?
