I love my FI.

Thats an AWESOME mask!!! LoOks goOd on ya'.

You can look up the owners manual with google.

He is just getting started as well. Exactly why I always tell people who are active hungry to expect their system to sound worse than a passive would for at least a few weeks. Obviously some people are quicker at learning how to listen than others, but it takes time. J-Road has done a hell of a job so far though and I know in the end this system will be more than sick. I want to give a BIG thanks to M5 (Sean) and Impious (Brad) for ALL the guidance. Without you two smart fellows I would have taken ALOT longer to learn what I was doing. You guys are WORLD CLASS!!!!! I want to ALSO thank EVERYONE else on SSA for their help and idea's, no matter how big or small.

Thank you sir. That f-ing vinyl takes ALOT of patience.

I know the thread ended up pretty long. I was ready to get em' in and guess I skipped a few details. I hot glued 3 blocks inside the pod, then used screws with fender washers on them to fasten from the back side of the door panel into the wood blocks. THEN I used 3- five inch long 1/4" bolts through the MDF ring ALL THE WAY through the metal of the door and used lock nuts inside the door. VERY SOLID.

That's fantastic!! I wish I was close enough to hear it as well. Out of idle curiosity, what settings have you ended up with thus far? (crossover points, slopes, and phasing?) I think it's particularly good for those who may not fully understand what correct phasing and tuning can accomplish to hear it from someone who's recently spent some time working heavily on tuning. Any chance you could give some details some time on the testing and the differences you heard when things started to come together?? Of course results will vary for all, but you could give some good insight as to why it's worth the trouble, I think. When I first installed the raw drivers, I played with each set individually. I listened with them at full range got famillair with what they where capable of. Then I trimed the xover points to keep what I wanted as a rough setting. At first nothing sounded that good. I could hear some sounds so clear and other frequencys where non exsistent, The Comb Filtering effect. This is where phasing comes in, once I switched the drivers side full range out of phase almost all anomaly's disappeared!!!!! Next was the Aura midbasses, They too were barking at each other and having some cancellation. Not suprizing concidering they are air pistons and pointed directly at each other. I switched the drivers side midbass out of phase and BAM, I was getting assalted with the kick drum!!! Lastly the monster BTL sub in the trunk. At first the sub was barking from behind me, even crossed @50hz. I switched the phasing and OMG I can't believe this beast can blend. Sounds like its in my LAP!!!!! The tricky thing about blending a sub is that when they are out of phase, they sound louder SO MOST novice will think thats what sounds best BUT it will NEVER blend. My advice for testing phasing is listen for the driver you can pick out the easiest, the one that sounds out of place. Sometimes the out of phase driver will sound like its barking over everything else. The other thing to listen for is canallation, So if one driver seems like its not making any noise then you may be getting canallation. There is ALOT of different phase combos, but I don't think its necessary to run through them all, just change as needed. Back to the x-over points. Well at first I asked myself what I concidered sub bass and midbass. I concider sub bass as 50hz and down and mid bass as 50hz thru 400hz. So thats where I started. I then did sweeps of x-over points and slopes to see what occured. I tryed shallow slopes with a ton of underlap, I tryed steep slopes with overlap just to hear the different effects it had on the sound stage. After all that I ended up with: sub: ssf @30hz / LPF @50hz 12db slope Midbass: HPF @50hz 12db slope / LPF @400hz 12db slope Full rangers: HPF @500hz 12db slope I have no underlap @ the sub/mid point which really helps put the sub in my lap. I did a little underlap inbetween the mid and the full range, this keeps from having the same frequencys coming from seperate sources and confusing the sound stage. I can get the full rangers to play lower but then the mid bass gets anemic, And like wise I can get the mids to play higher but then it brings the sound stage down. Next the fun part, Gain matching. I had been listening up to this point with everything set low. Now that I had the signals trimmed up I cranked up the Fostexs and these beautys REALLY came to life!!!!! Then I cranked up the mids until they were over bearing and then backed them off a little until the just started to become an extension of the full rangers. I have sub level control on the HU so I have the sub gain pretty high and just add as needed with the HU. Some days I like to get assalted with Sub bass and other days I like it mellow. I will say that with the correct phasing on the sub and crossing @50 that no matter the level, The sub still blends and sounds AMAZING!!! Then I did some "time alignment" . the T/A is straight forward, measure lenghts, do a little math, set everything and then listen with my eyes closed as I sweep the setting back and forth alittle until satisfied. Lastly I tuned a little with the EQ. I abide by the rule of "if you want something to sound better, take away. If you want something to sound different then add". first I had to boost at 40hz cause my box is so pecky @32hz. Then I Took away a little at 6.3khz to get rid of some bite. Other than that everything is flat. I DO NOT have any "Media expanders" on except for the satillite radio, which needs it. Let me know if you Got any questions. I am not the greatest with words SO I may of left something out.

Are you eyeballin' ME?

I got kicked in the egg basket in a pit once by some dbag. It was intended too. He got the old double fist behind the shoulder blades later and landed knees first onto the cement. Most of the time in a pit I end up carry out all the wounded with some other big guy making sure girls and 130 pound dudes don't die. I'm about 50 lbs lighter than I was a few years ago SO I definetly wasn't as effective as I use to be. Once the concrete floor got wet shit got interesting......

You will be good. I personally like to use a bolt through the trunk floor, with a lock nut on the underside of the car so the bolt don't come loose. Don't forget to make sure its bare metal.

The meds can definetly say some funny things.

I'm still limping from the mosh pit today. limp, limp, "damn them kids, I'm getting to old for this shit". Thank god its my Friday! Come on Friday.....

Lookin' good.

Well I survived the Gwar Show realitivly unharmed. only a few bruises and a scared mind. I don't think I mentioned it, but they played in a small theater SO that shit was Crazy. I would hate to be the guys cleaning up after them though. I couldnt imagine how much fake blood the sprayed. Most memorable moument would be Michael Jackson Fucking the alien baby.

Off to the GWAR show! I can't remember the last time I got off work this early on a weekend. feels good.

Do as the Sir Man suggested. Some people also suggest adding non hardening molding clay to back sides, to add mass if needed. I would paint the grills black in that particular car. Keep up the KILLER work.

Thats fucked up, If only they could handle their own advice.

Thanks for the heads up Duran. I unfortunetly can't make it bc I am taking the whole next week off for my anniversary (8 yrs). But PLEASE let me know when there are other shows in our area, as I honestly would love to make it to a few just to hear what is possible.

DC Power FTW Baby!!! No need to apologize for taking your time, takes the smart way to do things. BTW glad you like the Type Rrrrrrrrrrrr's (like a pirate,hehe) I am going to install my pair in my new truck soon. (build log fosho)

You and me both! I am SUPER HAPPY with the way things sound, BUT wish I demo it for people that would appreciate as much as I do.

They worked good. I needed ones with a 1/4" hole in them to get max contact on the battery terminals so they fit the bill. I lightly criped them when I soildered them. On another note I am in love with my fostex's. And I have the phasing dialed in, I have the x-over points blending, and I ALMOST done matching the gains. WOW, the SQ is EPIC!!!!! The sound stage is AMAZING!!!!!

The vid looks like the bass gets violent in there!!! I likey. I'm sure Mikey likey too.

Teh woman use to perform in the Rocky Horror show in Wichita. I <3 Corsets. I've only seen it on TV. FREAKS baby, yeah!

Holy Shit thats ALOT of writing. Sounds like your pretty happy with the set up? Wish I could hear it, But until then......
