    emdzey, the fact is, untill you pass regionals, it doesnt really matter what equipment you choose.

    Ive been beat out by people who were running $40 ebay subwoofers before. In kind, I've run DD midranges and three tempests in my car and beat over half my competitors.

    whats important for you to do to really get into the competition scene, is to fine tune your ear for staging and phasing. this means major major seat time playing with speaker positioning in the car. when you start to do this (and this can take weeks) red and I can start to help you zero in on stage characteristics, specifically stage instrument positioning, depth, height, the important stuff.

    Once you have potential phasing issues dealt with, we can start to do tonality. how the instruments should sound (and this one should be fun, some judges listen for different instrument aspects) on the stage in your car.

    Why go with expensive equipment? well, some speaker characteristics can aid in setting up your sound stage. One particular characteristic I am playing with now is the idea that a tweeter with a low FS can enhance, improve the ease of on axis staging. This is almost a non issue in a car anyways, due to the complex accoustics you will experience.

    But quite frankly, absolute phasing is the first and more important hurdle to overcome, and its probbaly better to do it with cheap speakers, such as lpg silk tweets, koda midwoofers, and as many subwoofers as your block rocking heart wants (youll naturally decrease these as you get a head for SQ) and slowly pare equipment to the essentials as your tuning ability is honed.

    did I mention I spanked the utop car with my DD's and vifa tweets? equipment isnt everything!

    and red, I know they are a bit pricey, but have you considered the LRx series rather than the VRx? I think the industrial design of the heatsink blows away the VRx, and that the noise floor in the car, off or not would prevent hearing the difference....

    oh, I forgot to mention what I look for in wiring. I look for a high strand count. the *general* tendancy is for higher strand count cabling to flex much more easily, and your back and fingers will thank you as you push it around laying it in your car

    as to OFC, its cool, but the fact is ETP copper is just as conductive. same with the silver coated OFC wiring. I wouldnt worry. Most wiring if not all is ofc these days anyways. probbaly have to pay more just to get ETP copper ;p

    thing is he's in the Phillipines....he owns a business that installs carPCs and he's trying to go out his first year and prove that a computer can sound better than a head unit.

    This is exactly what I was telling him on AIM. The questions he was asking on AIM were essentially impossible to answer for someone who has yet to compete.

    Once you have potential phasing issues dealt with, we can start to do tonality. how the instruments should sound (and this one should be fun, some judges listen for different instrument aspects) on the stage in your car.
    exactly! I just had a guy tune my car this past Sunday who judges and competes on a pretty high level with USACi. I know for a fact that what he listens for is completely different than other judges, but I just needed a starting point....

    honnestly, I haven't gotten to the point of sitting down with a price sheet and compare what it will cost me and what I can sell my current arcs for....I'll keep it in mind though when I look more indepth at them! Thanks for the heads up!

    I really prefer the look of the LRx amps, even over the VRx. I kick myself once a blue moon for not shelling out the extra $200 for the LRx.

    i hadn't realised you were doing *quality*

    sounds insane thinking about it in a complex baffled, padded box - reflection-a-go-go i feel.

    My kid brother does pro-audio, and he's got reference monitors in his bedroom.

    They *SCARE* me, listening to top ten tracks you can hear people cough in the *control* room during the recording sessions :P

    decent jazz sounds mindblowing, the sensitivity is amazing, but due to the accuracy they make mass produced cd's sound like *wank* because you can hear *all* of the imperfections.

    It's sort of cool.

    is it all measured subjectively by judges in a car then? how do you judge qs?

    technically it all comes down to subjectivity, but on theory its an objective measuring system. what you call a 4 another judge may call a 3 of fiv,e and so on. not too hard too see why scores vary so widely from competition to comp, judge to judge!

    in iasca, you are judged on several criteria. actual quality of sound is important, tonality, timbre, realism, etc. But also other stereo characteristics, too. linearity, staging, immaging, height, depth, width (for every 4 inches inside the tips of your side view mirror you lose a point. and thats point PER side). its things like that

    thtas about a third of your total score. next you give a presentation of your car to the judge. install, wiring, aesthetics, safety. anything the judge cant see you need to document in photos. if the judge cant see it as a photo or in your car, you get a 0. all batteries vented, fused on both sides, etc etc etc. you are judged on your car and also your presentation.

    the more questions the judge asks at this time, the better. it means he is looking for stuff to dock you points on, and cant find anything.

    finally, spl and RTA, if you are a rookie. SPL is -1 point for every dB under 135 you hit, you have to use the iasca disc. no time limit, within reason. you hit 135 or above, you get all 30 or 35 points. you get anything below 100, you get 0 points. if you are a rookie, they wil RTA your car, and you lose points based on how peaky your response is.

    whew! your judging paper is not on an 8.5x11 paper, its like 8.5x22! looong list, and as you up the classes to pro, the number of criteria just increase!

    red will come back to tell you about usac criteria. usac left california in 2001, we havent seen a show since then

    that sucks that they left cali! I know this last year they came real close to holding a joint finals...something fell through though (think it had a lot to do with egos honnestly....lol)

    Being that the rules JUST changed for USACi for this competition season I'm not real versed on them (there hasn't even been a show that's used them yet, this coming weekend down in South Padre will be the first weekend for them, and it's a tripple point show!)

    I do know that for this season they redid the rules to focus more on the sound, not so much on how much money you have to blow on the install...lol

    which is nice, because in the process they now have a class that is dedicated just to beginners, if you roll up and try to compete in teh lower classes, the judges reserve the right to bump you to a higher class, to keep the sport compeditive

    Once I get a score sheet for my class (intermediate Pro) i will know mroe about EXACTLY what they are looking for this year. You can read the current rules all you want, but till you see the score sheet you don't know for sure...lol

    Safety is a major concern when judging install, but the install is only like 60 points in my class, sound constitutes 125 points! SPL is your score (say 145) minus 100 - so it would then be 45. I would still like to see something different here, because you can have a GREAT sounding system, but joe blo with 4 12s can blow you away with a 160 to your 138....before they were considering moving the decimal over one place (when you hit a 143, it's actually a 14.3).
