Awesome Pics Bro ... :drink40:

hank you sir!

I want a crimper like that one, this swedge-on tool is pretty easy to use though, only downside is I have to walk back and forth to the bench to use it.

So worth it, wish Id have gotten it yars ago... best $50 tool ever spent.

nice! looks to be going good so far

thanks spy!

your keeping it an ib setup without ib woofers? is that ok?

It's not an IB setup, I was using the IB3s in a vented alignment. The total is 45 cubes, thats 11 cubes per sub... tuned with a port.

The Blueprint Audio subs I bought off a guy that was going to use them IB, so the Blueprint subs are "acceptable" in an IB setup, though 11 cubes @ 23Hz isn't IB

I don't know if I can hear it surpassing Xmax or if it's the hard plastic dustcap against the air behind it, but around 1/2 way it gets noisy. Not bad/broken noisy, just motor noise or something.

I think that was the sound of voice coil hitting back plate

nope, we finaly figured it out, it was CLIPPING! I was running an EP4000 bridged 2ohms, each channel was seeing a 1ohm load, we were clipping with over 3kW!!!!!!!!!

never been able to take a pic of the whole wall because the seats are in the way but I am doing some touch-ups and mods to the wall for the new subs so I have the seat pulled out. I can't get the passenger seat out, though, it has a pull out storage box mounted to the floor beneith it, I can't get it out, I need to get it out to get to the seat bolts. She ain't pretty, but since when has my work ever been?

Subs arrive tomorrow, will do some free air break in on the EPs then away I go.

Ummm. Are your amps and batteries inside the box? WTF

Looks like it, wonder if he climbs through one of the holes when the subwoofers aren't in, or if he can open up the back?

yes I have vibrated 6 amps to death nnow, they wont warranty me anymore, because my amps are inside 45 plus cubic feet, whereas you really cool dudes have systems that you claim are 10 times louder than mine in a trunk.... thats aproximately 13 cubic feet.... and your amps are in that trunk.... shit, I just blew yet another amp, you keep laughing away, Im going to go cmmit suicide now because you made me feel stupid

I never said anything about it being bad. I could be full of shit, but I don't see any difference in terms of dangerous vibration to the amps if the amps are mounted inside the box or outside. After all a speaker creates two waves, one goes into the box and is trapped (sealed) so there's no cancellation and the other goes into the cabin pressurizing the air. Or the backwave goes into an enclosure and out through a port... Either way, to me I would think the pressure in the cabin vs pressure in the box would be close, so it wouldn't make a whole lot of a difference to your equipment.

:) havent had a problem yet. Its been good for several reasons, one is shorter wires from the front alt(s) and battery to the rear batteries, then having as short a run as possible from the batteries to the amps, then again from the amps to the subs and front stage. 2nd is anti-theft... I live in the worst part of town, litterly have drug deals go down in front of my house. Pimps and hoes that do business right in front of my house. Two or more cops drive by every five minutes. Last summer I had someone rip the cover off my electrical box and pull my breakers to my house to kill the security lights all around my garage and house then they tried to get in my garage. I woke up with NO power! Why all the security lights? Crazy stuff happens all summer long at my house. The liquor store is a block away and people will get their beer and make them selves right at home on my pourch. Cops will pull up while I am out back working on other cars and tell them to move along lol. If people want to steal my amps, they gotta crawl through my port with a light and powerful cordless...after busting out my window in the van lol.

Seriousely I havent blown any amps or vibrated them...yet...lets see what the new subs do :D :D

Seriousely, not even kidding. Just today, my newest neighbor in the apt next door got screwed over by the landlord, he got hired and moved in for free to do maintainance for the slum lord. He hires guys, makes them big promisses, lets them work, never pays up. The guy across the hall from him is one of the 2 old maintainance guys that got screwed. The landlord wont evict him because everyone knows he owes dude money. The old guy got punched in the mouth 2 weeks ago for fighting with the new guy. The cops are sometimes there twice a day breaking them up. For the last week the new guy has been hoofing it..he was driving the slum lords Mercedes but he took it back... he is over here trying to ask me "you need some drou? I can get you some great nuggs. Dude, that guy screwed me over I have nothin help me out man." Today I was teaching my girlfriends son what to look out for, to be careful. He needs to know what people are up to when they pretend nice. The guy went outside to a car that pulled up in front of my house. I said "watch. he is going to get in the car for a couple minutes, like they are friends, but he isnt going to leave with him. The guy isnt going to get out and chill. hes gonna get out and go back in, the other guy is gonna leave" sure as shit. Hes always eyeballing my tools and house, hes always tweakin bad.

2 weeks ago I pointed out a girl and guy walking together, the guy walking off, the girl looking around. old guy in a nice car picks up nasty chick and they leave. 15 minutes later that old chick and the dude are walking up and down the street again. not safe for him to live here, but what can we do. we watch out for people in the neighborhood, they watch out for us. is what it is.

Any given summer day, my house looks like this...people driving by come to check it out, want their stuff done:

another day

i didnt even know this guy, he walked by a few different days and said "hey nice van" then one day just pulled up, started BSing, started smoking a blunt, said "hey man can I borrow your outlet?" Now we buddys.

CIMG1394.jpg

every other day with all the people parking over the sidewalks or on my boulevard or people cranking their stereos

CIMG1400.jpg

when I first moved here this is how I let everyone know I am th speaker guy. now the whole town comes over lol

CIMG1651.jpg

the guy walking toward me is litterally a pimp, he lived next door, he would come sit on my pourch, his woman would come over... a john would show, she would go up with him, come back, nother guy, repeat. When "pimp"... thats really his nick name...when he wasnt there we would all time how long johns were up there...8 minutes once! The got evicted and moved a block down then got busted for meth, the old maintainance guy lives in their apprt

CIMG1871.jpg

hood guy wanted a system, then he wanted me to keep doing it, wanted me to get "hot gear with hood prices" and he always stood over me when I worked so I stopped doing work for him

cut up 4 old mounting gaskets since the counter sunk holes were cut to fit without gaskets, and not using gaskets led to air leaks

the little guys arrived today, currently breaking in two bridged series 4 ohm of an EP4000, she is so much happier at 4 ohms... pushing two easily and barely even warming at all

Jim did an excellent job packing them up, all three appear to be MINT.

1st one is installed while I break in the rest

so I had another great idea... why build a break in rig, why not bend the shipping crate?

one of the EPs has acted weird since Ive gotten them, one has brighter LED lights, clips a tocuh easier than the other, and gets warmer than the other. As expected during break in one started to get wartm so I toggled them as planned, letting them take turns. The "bad" one, when I turn the PC volume down to 0 every so many minutes to let it cool off, seems to have a loud BUZZ, not necessarily 60Hz or a grounding loop, maybe so actually but like a leaking cap when it gets warm? When I shut it off then back on it stops. No clipping lights, seems fine, just after going full bore for a while when it gets warm, not hot, when I remove the tone one remains :(

anyway

well what to say what to say. I was wrong? Everyone else was right? Wait... Ive said that countless times.

These subs are wicked in the enclosure/tuning/power requirement I ended up with. This is me still sliding in my excuses. Listen, I started off with 110 cubic feet and a 15Hz tuning. My towers dont load the subs hardly at all, I barely get any excursion reduction at tuning and I get close to peak SPL at tuning. That wasn't true in the final result of the van, but of course not, 45 cubes is a lot more restrictive and loads a TON more... then theres the 24Hz thing vs 15Hz. Not even going to try to explain myself away there.

Also, I had never done a wall before, I had never even done a double baffle or a recessed/countersunk mount. I had this great Idea of making the two outter rings a tiny bit too tight since I used 3.5" screws that should pull the sub into the counter sink making it anti-theaft, even more air tight ( I didnt use gaskets...big no-no) and to support the "weight" of the subs. Now that I have "real" subs I realize even these pale in comparison to 70lb plus drivers.

So I fixed the air leaks as best I could... I chizzeled out the outter two layers and I chopped up some mounting gaskets so ive got rubber seals now. On music air actually blows through my port! I believe before, my enclosure was leaking around the sub cutouts, making my port less effective, and as effective as it still was...well the IB3s weren't strong enough to fight it.

So anyway, with the 110 cubes 15Hz tune I had a nice flat predicted responce with a big spike from 10Hz-20Hz like initially wanted. But ending in 45 cubes 24Hz, I had a nasty peak. I tried to fight it by lowering the sub level and maxing out the EQ at 25Hz... still leaving the 30Hz on down lacking, but also killing the 50Hz on up material.

So I shut the EQ off before I fired up the new subs. Already they were AMAZING. Much louder and much flatter, much better sounding INSTANTLY. I could hear the difference the first 5 clicks before I even gave her anything. I drove around a while, loving it. Then I dropped the crossover to 80Hz. Ah, there we go. I was overcompensating the EQ by raising it to 200Hz. Now there's more separation from the Extremis. Thats what made me do it, the Extremis had disappeared with these subs. I thought about it. Dropped it. Much better.

Well with that done, I cranked the sub level back up. WHOA! Now were talkin!

So kids, dont listen to me, IB3s arent designed for even large vented enclosures. My towers are proving themselves, they do pretty good, but they have SIX times the airspace as my van.

So far i am a happy guy. I am no Steve Meade or any of the other 4 18" setups I have seen vids of. But when I get my 2nd alt in, I'll be doing much better. Even the IB3s could get loud as hell for short periods but voltage drop was nasty. These get louder with less excursion having sealed the mounts. These get louder continuous since they can handle the power and theyre more efficient.

I know, I know, you were right, i was wrong. Now Fi doesnt even want to talk to me.. what do you do. I led the masses astray. Well i was a hater, I couldnt afford Qs or Maelstroms or DPs.
