how much volume is in the spare well?

[Eric]

I'm thinking of a image dynamics IDQ 15" or RE audio 15" in the spare tire well for my touring.

I'd rather not raise the floor, but i might if i need to.

the IDQ needs 1.1-1.75 cubic feet and i'm leaning towards that since i really liked the IDMAX that i have.

I've always wanted a 15 or 18 and with the touring, i won't have to worry about the sealed trunk crap of the regular E30's.

I'm in the states at the moment so i don't have an E30 off hand to measure.

Should be something like 1.45 to 1.5 cubic feet IIRC.

[BrewCity11]

yeah, i was gonna say 2.1 based on guessing dimensions

[92 mtechnic cabrio]

enough.

I fit a 1 cu. ft. square box in the spare well no problem,

[Eric]

sweet, looks like i'll be rockin a 15 in the wagon!

[92 mtechnic cabrio]

damn

I want a touring for this very reason

[BrewCity11]

If i were you, i'd chop out the whole tire well anyways.

I'd cut it out + a little more to the drivers side since its offset, and replace it with a shallower, but larger, rectangle tub.

Two 10" or 12" > one 15"

Andy built a 10 sided box. We came in at 1.92, gross volume.

no cutting, that's big dreaming you've got there, and i'm on a budget/weekend project.


In my old E30 M3 at any given time i've had

3 old school JL 12W6's

1 polk momo 12

2 12 inch alumapro alchemy's

3 10 inch arc audio subs

1 12 inch imadge dynamic's IDMAX

this time i'd like to try a 15. I know 2 12's is better, i've done that. i'd like to try 1 15.

Luke - 1.92 eh? that's almost large enough for a ported enclosure... hmmm. do you think the E34 spare well is larger than the E30 one? I was actually going to copy your 10 sided box. I tried fiberglass once before, but it was my first atempt and a major fail! haha.

edit: oh yeah, update that thread!

That was an E34 touring, second in 2 months I have done.

Actually, Andy did 90% of that install, including the box build.

I mostly did the front mids...which took me about 10 hours of thinking and 3 or 4 hours of work.

You should hear the fucking midbass...best "thwack" of any E34 I have ever done.

Be careful, idq is a totally different beast compared to idmax.

[StereoInstaller1]

IDq is a pile of shit, IMO.

Stamped steel basket, cheap 2" or 2.5" voice coil, single magnet...should be $120, max.

Exile has a new SQ 15". Beast of a woofer, but $700 retail is just too damn much IMO.

I do like the 2 ohm DVC setup. 1 ohm monoblock or a 2 channel on a single woofer...nice.

To each his own, but I hated muddiness of idmax compared to idq. I personally care about sound more than anything else. I'd love to hear one of your boxes though Luke.

[StereoInstaller1]

My big bitch is no listing of Moving Mass (mm) so no idea of what the "unsprung weight" would be.

that is the #1 cause of muddy bass, no doubt the idmax is muddier than the idq.
