what that tells You is that You have a suprsing spike at 48-49 hz...? You say Your box is tuned to 25? Odd - impedance usually spikes around tuning, IMExperiance. For example, my DD 99 with Dual 0.9 coils - each coil reads 9.25ohm in box @ 47hz (tuning). Okay, well, I'll ASSUME that when You adjusted the sensitivity on the amp, You set it at 50hz (Per James' tutorial)... if so, You did something like: 40 volts x 1 ohms (for example) and called it a day. What this graph shows you is that in real terms, you set the amp for 40 volts x 3.2 ohm actual. Instead of getting 1600 watts, You are getting 500 watts. A difference of 1100 watts. I don't know what the dcr is for your setup though. RLP's are Dual 4.0ohm are 6.1 in series... so standing dcr should be 3.05 per coil (standard TC coils ). If You wired all (4) coils in parrellel, then You should see 0.7625 actual free air (27.8hz - fs). Now, per Your work up there, at 28 hz, actual in box impedance is: 1.5ish. Make sense?

hey... when did we lose our :offtopic: smiley?? LoL

ummm.... sadly no. Just got my new Fluke 333 clamp... impedance at 47hz? much worse then I feared.

More surface area implies more port area ... <{POST_SNAPBACK}> implies in the conventional term, but thats not accounting port wall surface.

*poof*

iirc it's 58lbs per 1st optima.com... who also has the dimensions.

well, 6.5"x12.4"x9.4" & 60lbs... not worth it.

Yea basically... throw in the 60lbshipping weight and fawgitabootit. Make a friend at Sears.

radio shack baby... Its just what I had laying around ATM. Minor details pfffft. Nope, no burps yet. I only burp (at home) during the daytime when the neighbors arent home. I'll tell yah though, Tones HURT. LNT is anemic with this tuning though. LoL

Blue 31's for ~160. A friend works in the shop @ Sears. 10% off for him, an additional 10% off on Wednesdays.

LoL... surely. Sub tips in ~58lbs... this box is only ~30lb so far.

BTW - that was 10hz (tuning is 48). No quotes on power though... havent set anything up yet. Boy does this suck for music.... I'll make the plug tomorrow. -Nick

Giving the 9915 first crack at it... apparently the basket cutout is a hair more then 14" Soft porn for You all:

Rear seat line for reference:

For the time being the Optimas are not here yet. grrr... But for $160 each, I cant complain too loudly. As it stands right now (ready to go) I've the stock '02 Delco batt and a freshly charged interstate Marine / RV battery. The stock 150 amp alt and so on. I have yet to apply any deadening - other then the front doors... that'll be tested out in the coming weeks as I get to burping. She's ready to go, baseline anyhow.

who wants pics?

Truck's almost done. Need to call a guy about some batteries... thats it. Gonna try to get some TL time in tomorrow on what I've got though.

thats worth a If the wife'll allow. <{POST_SNAPBACK}> I know for a fact she won't. That's fine. I'll find someone with long hair and have them stick their head in the hatch. <{POST_SNAPBACK}> hee hee hee

If You want loud and looooooooow.... You'll wanna go large. very large. You could get 16ft^3 with a wall? How about a half wall - window line? So that You could still make use of the rear windsheild... Really, if You can, the larger the box with the lower tuning will have MUCH greater output down low. I'm guessing it'll be even moreso since this woofer is a low ended motor. 12ft^3, 120-180 in of port, tuned ~25.

Like the screenname. Nick

caught up.

thats worth a If the wife'll allow.

its junk now, sell it <{POST_SNAPBACK}> trades? uber?

LoL - came in today. Umm... <{POST_SNAPBACK}> Heh, at least I didn't have to do half of it. <{POST_SNAPBACK}> eh, mine was not much better.
