Either i'm crazy, or my car just sucks...

Just for grins today, when i got done with my midbass enclosures for my rear doors today, i headed to best buy, to "borrow" a couple type-r 12's, just to see how i liked them compared to my type-x's and the l7's, since i'm having trouble getting either the way i want.

So i got the type-r's, and dropped them into my type-x enclosure:

2.0net (don't know what it is with the r's in there instead, maybe 2.2?) tuned @ 30hz, so probably ~28hz with the r's.. Hooked up @ 2x2ohms for a 1 ohm load on my bxi2006d, so ~1800w rms.

And i'm still not getting loud! //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Played with phasing? Check.

Hatch open, hatch down? Check.

Check gains with o-scope? Check.

Played with the volume? Check.

Faded to all 4 individual door speakers to make sure it's not a phasing problem? Check.

Windows up, windows down? Check.

Played with sub sonic filter? Check.

Played with x-over and x-over slope? Check.

No dice.

Is there anybody in my area that can give me a 2nd opinion?

I took a gander at the speakers with my hatch open, and they're MOVING! Not bottoming out, but definitely excursion-video quality moving, and still not even close to where i want to be.

If someone could give me a 2nd opinon, that'd be much appreciated, maybe i'm just insane or deaf, but it doesn't seem very loud. //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif In fact, they sound almost identical to my type-x's.....

I know that I had a speaker wire to RCA conversion thing and it has two screws which had to be turned in order for it to get louder, I got worried at first too. IDK if you have one of those, but maybe that'll help

try wiring one sub out of phase... i had to do that on a install today... the amp was labled wrong... ( 2ch amp )

^ thats a Line out Converter he's talkin about

Can't be a line problem, was still able to bring my amp to a clip when setting my gains.

Something's awry, tho.

I think tomorrow i'll try and hook both speakers up to the same terminals.

It's a monoblock amp, but has two sets of terminals, could be anything.

well the type r's probably arent gonna get as loud as you want them to without a tcab box

Oh christ, another one bits the dust on the hype.//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

ummm... sounds like your box is the problem...
is it 2.0 net, or 2.0 net per sub?

if the entire box is 2 cubes (and i'm guessing with that 30 hz tune, the port area is small as hell to keep box size down) THAT is your problem... those subs want a bigger box and more port area...

i'd give 'em *fires up BBP6* 4 cubes with ~77 inches of port area... if your cabin gain is anything like mine you'll be in the 140's from 25-50hz (read as: low end MONSTER) with 1800 watts. Vent velocity will be reasonably low, and you won't exceed xmax until you get under 25 hz (if xmech actually IS that retarded number that alpine claims, you won't bottom out until you get to 11hz //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif )

so... big box + big port = loud //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

2 net per sub, 2 x 16" port area for each. it's a **** big box, actually

i think my car's just too **** big. or my expectations are unrealistic

maybe loud bass just doesn't phase me the way it did back in the day, i haven't had a system for a few years

i've been throgh 2 type-x's, 2 15" l7's with 2 enclosures, and just trying the r's to see what the deal is, and nothing's doin' it for me.

and there's no way i'm building a wall in the audi.
