  1. I hope this isn't too vague. I'd bet you've done all the homework you're able to do and are still at a loss.

    I will assume that your stereo and car electrical are separate from each other, or at least the problems are isolated to the car only and providing the alarm isn't at fault.

    I'd look at the wiring schematics for your scion and see if you are able to trace the systems that are being affected to a possible common point, whether it is a common ground or the eec/pcm.

    The clock resetting itself for instance should be completely separate from your stalling issue. It could be a loss in power to the coil or a drop in fuel pressure or even the idle air bypass valve malfunctioning ( I don't know what scion calls this).

    Who knows, it could lead back to a bad ground or computer in the kick panel. Too many systems are being effected for it to be multiple problems, IMO.

    Intermittent problems are a real bitch to diagnose, unless you find someone else that recognizes ( and has solved) the same problems you're experiencing.

    Have you searched for these issues, assuming they're not audio related?

    Good luck Shizzzon!


  2. If you decide to tackle the 2- 12" box and the angle cuts, you have the necessary tools to do so.

    I'd draw the box out, looking top down and from the side, on a piece of wood big enough to check yourself before you make any angle cuts, use it as a guide.

    Do all of your pieces to size, then miter them to what you need, if you're unsure.

    If you mean to do compound miters and you're new to this, go with the 10's.


  3. If you stick to WC on the CPU only you'll be ok.

    If you also loop(s) the video card(s) into the loop it starts to be a pain in the A** if you need to remove anything from the case.

    You will need to do some research, if you haven't already, on good low CFM radiator(s) if you want to keep the noise down.

    I've got an Antec 1200, which I love except for the dust filer access.

    I did allot of mods to it. I'm running 2- black ice radiators (inside the case) along with 2-8800gt's, north /south bridge and the e8600 @ 4.0 ghz. in the loop. Also 2-Raptor x's in a raid array.

    I know, it's time for a serious upgrade.

    I'm going to go with the 2500k sometime soon, as well as a triple monitor setup and ssd's sometime this year.

    What video card you going to go with?

    Here's a couple pics, raptor mod and fitting the radiators.

  4. I plugged your numbers into BBP6, assuming they are correct, you should be close to 34 hz.

    With the H/W dimensions you've provided the port should be ~29" long.

    Do you loose control of the cone much below 57 hz.?

    If you don't I'd assume the enclosure is tuned close to where you wanted it to be.

    Turn the sub/infrasonic filter off, don't go nuts with the volume, and play some tones. Where does the cone move the least and where does the cone really start to move.

    This could be a good indication of where your tuning really is.


  5. It's not my choice in cars or rims, but the pics look great. I can imagine the work/hours it took to get there. Very nice job.

    One question though. I see people with tires that are much narrower than the rim like in the pics you've posted.

    What's the deal?

    Is it a clearance issue to get the rims to fit?

    I don't mean from a performance standpoint, but it seems as though they ran out of cash for a wider tire.

    I don't mean to single you out, but since you posted pics that show what I've seen in my area I thought I'd ask.


  6. I have the 88120 dvc as well as (3) 88120 ti dvc.

    I've tried them both ways and they love a ported box, IMO.

    I'd go with ~1.75 c.f. net.

    Pencil and paper gave me 1.55 c.f. as the optimum volume.

    I built the first enclosure to that with a 32 hz. tuning. Absolutely loved it in the back of Fox body hatch.

    I had "wind" in my car for the first time. It would blow out my zippo.

    I believe the port dimensions were something like 1-1/2" x 12" x 36", not sure I built the box along time ago.

    I don't know what the in car response was, but it modeled on BBP6 with only a 3 db rise at tuning.

    I powered it with a JL 1000/1, never had any problems.

    If you do a search, you should find a thread stating no more than 2-2.5 c.f. net.

    Be careful with you're excursion, the polyether foam surround will crack/tear if you wang it too far. I don't believe the former will bottom out on this motor, no ticking noise.

    The rubber surround on the 88120 dvc seems to be more forgiving.

    The box.

    The sub.

  7. Lookin good so far.

    Is that insert/bracket plastic or metal? Installed it looks like painted metal.

    Edit > I looked back at the pics again, it's got to be metal. Very nice.


  8. Why is everyone so angry about what his opinion is on the design or what he believes should have been done to make this a better design to him? If the person is happy with the enclosure then why should he care about other people's opinions on what he could have done differently? Not everyone is going to agree with everyone else so why take it so strongly what ///M5 says? You say he has no credentials so why would you care about the opinion of someone with no credentials? If I were to say the same comment I'm sure no one would have cared or made a big deal about it... Let him have his opinion and you can have your own. There will never be a way to make everyone agree so why not just be happy with what you have and enjoy it like it was intended to be in the first place?

    Resolution, plain and simple.

    As long as the guy that paid the bill is happy with his system is all that matters.

    It was stated that a meter would be placed in the car and numbers would be recorded.

    There aren't allot of "stand up" people in this world that will admit to being wrong about something. Even some deny it after they're caught red handed. No, this isn't in reference to anyone on this forum.

    If the tests are done and the numbers don't support the builder, will they be shown? I'm starting to think that they won't. Does it matter in my day to day existence, no, not even a little bit.

    Why would I like to see the numbers, because a second thread was started to "sort things out".

    So, some of us are waiting to see what occurs next.


  9. Who was this ^^^^^ post directed at, anyone in particular or no?

    Yes, it can be proven that it's accurate, that is factual. I thought that was the other side of the debate (opposite of M5).

    However, accurate or not doesn't mean it sounds good to you or anyone else, that's subjective.

    it was kind of a basic reply to everyone. lol.

    and no. if you read the whole post, HE can not prove it. unless of course he has the same exact car, in the same exact scenario, with the same exact build... the math behind m5s argument is factual, but irrelevant to a real life, in car build.

    as for it sounding good, you're right. that is subjective. as such, m5 shouldnt say it sounds bad (especially when never actually hearing it) and maliboom shouldnt say it sounds good. it sounds good "to him". others have said it sounds good "to them". but as a generalization, thats something that has to be decided each and every time by each specific person.

    No sir, that's my point. If it's accurate it can be proven with a meter. This is where M5 is coming from.

    If the OP stated that he wanted sound quality, then it should fit a specific set of goals. Those goals could be no more then 3 db. variance throughout the enclosures range, in the vehicle. Nobody cares what it sounds like outside of the intended vehicle.

    This can most certainly be measured.

    This also doesn't mean that it will sound good or meet the OP goals. I'd assume most people would not like a system that falls within this criteria. Even M5 has stated that a flat frequency response, "sound like shit". I'm at least 95% sure he has stated this in the past.

    Goals that were stated don't add up to M5's interpretation of the pics/design he saw and he was compelled to say something to get "your" attention. He did exactly that.

    Whether or not the questions that were asked by the OP or the builder had enough info. for M5 to give an intelligent reply, I don't know. I'd have to go back and read the original thread again.

  11. as for the whole credentials talk, its not that hard.

    http://www.termpro.c...2011&Method=202

    thats obviously not all of my history, but down at the bottom.. you'll see world finals, and the #2.

    and the funny part is, that doesnt make me an expert at all. but it at least means i have an idea of what im talking about

    Honestly, no it doesn't. That's not an insult to you in particular, anyone who successfully competes or operates a business designing enclosures. We've had this (or a similar) discussion before on this forum, ask Cableguy ;)

    In the SQ arena I've seen many well respected world champions who've been praised for their installation and tuning abilities for many years speak misinformation and hold on to beliefs which were very much against the facts. Were they "right" because they could point to 10 systems that they've installed and tuned that won competitions, or because they have a shelf of trophies themselves? No, they weren't. Their information was just as wrong, regardless of their "credentials".

    The point is, credentials aren't part of the discussion. They have no place in it. They aren't relevant. Information is accurate or inaccurate, "right" or "wrong", regardless of the credentials of the person providing the information. Having credentials they can point to doesn't make their information any more right, and not providing credentials doesn't make their information any less right.

    Does it matter if M5 is a 30 year old keyboard commando sitting in his mom's basement if the information he's providing is accurate? No, it doesn't matter at all. The information can stand on it's own, regardless of the credentials of the poster. That goes of people on both sides of the discussion; M5, Robin, yourself, etc. If the information they're providing is accurate, then it's accurate regardless of the credentials of the person providing the information. If it's inaccurate, then it's just as inaccurate regardless of the credentials of the poster.

    This is the Argument from Authority I mentioned earlier. Information isn't inherently "correct" just because it's coming from someone assumed to be an authority. Conversely, information isn't incorrect just because it comes from someone not assumed to be an authority. It's a logically flawed argument. If the information is accurate or inaccurate, then it can be demonstrated to be such regardless of who's providing the information. Credentials have nothing to do with the validity of information.

    Very well said.


  12. The only experience I've had with M5 in one of my threads was a positive one.

    He asked for more information on my goals, the placement I had to work with and what the rest of the system consisted of, he was very clear on what info. he wanted/needed to help me.

    I provided the info. in the next couple of posts. He then pointed me in the right direction and I did the work/testing, it was my project after all.

    I've seen plenty of threads where the OP gives no info. but wants all the answers, it gets irritating.

    If you put forth the effort to pose an intelligent question, you will receive some useful answers. You may need to do some searching to understand the answer, but you at least have some a direction to find them.

    Let me say this also, "YOU ARE NOT OWED ANYTHING". Allot of people think they are, and this is not directed at anyone in particular.

    The one reoccurring thing I see from M5's posts is to stop misinformation, I thank him for that, along with others on this forum.

    I appreciate the fact that he wants you to think/learn for yourself, not blindly follow someones advice.

    Isn't it better to understand what you're doing then to do it because someone else has?

    he posted what he had to say in a build log where someone was just posting pics if their build that a professional/ someone with alot more experience was doing. the op had another thread where he asked opinions on another box i believe, but not about his current wall. and the op didnt ask any questions during his build log that required M5 to be as he was, or anyone else for that matter. and the log wasnt even full of misinformation given he wasnt posting it to teach anyone, nor was it there to ask questions about a build that was already in progress. now if M5 wouldve posted some of his less insulting statements in the thread he posted then it would be different. and thats because the OP was asking for suggestions and advice.

    I posted my experience with M5, not anyone else's.

    The misinformation was a general thing I've seen from M5 and was not directed at you. It seems as though you're looking for an argument, to me anyway.

    Trying to make sense of your reply is making my brain hurt. Do you read what you've typed after you've typed it? I'm not trying to be an ass, but that is hard to read.

    Well, his statement about the math being wrong got your attention. Didn't it?

    If I didn't know how to do the calculations and was relying on someone else, I'd most definitely start to ask some questions if it's my money on the line. Wouldn't you?

    I understand M5 can be hard to take, but the bottom line is that if you ask for help he'll give you help in his own fashion. When he sees that you're making an effort, he's more forthcoming.

    If you can't see that, ignore him. He's helped allot of members and you'll not change the minds of the ones that he's helped.

    You stated you prepped the surface properly and that you used a roller, I wasn't present when you applied this so I'll take your word that you did that.

    Looking at the pics you posted, I don't see any creases, cuts or tears in the foil from sharp edges, seams, curves around the decklid bracing or the edge of the roller.

    When I put mine on I had these marks in the foil or had to make the cuts to follow the curves, everything is staying up so far, put it on mid summer last year. It was in the mid to upper 90's for weeks and it's a black truck.

    It wasn't peal n seal ,but a very similar product from home depot.

    I Hope you have better luck with the dynamt. That sucks having to remove that stuff!
