WC's never ending s13 project

[OM3GA]

I think he means do you know what your temp was with the CX rad and if the Koyo will be a lower temp. Nice looking build thread i hope to get mine up one of these days. At least you arent on page 50 yet come on man you can do it! I believe in you haha

[White Comet]

well if that's the case, i can't compare. the cx racing rad never made it that far. as you can see from this thread, my car doesnt run yet, all i tried to do was fill the rad and that was all it took

[Scuffed_ChukiCoupe]

whoever's door that is how'd you get the crossover to stay there... im guessing double sided tape?

[mrgreeneyes]

I just saw your component speaker crossover location. While it's a good hiding place for them, it's not the ideal location. The crossovers need to be as close to the speakers as possible.

yeah, that makes sense. thats why OEM's put crossovers right in the doors....

oooooh wait. they're built into the amplifier/radio. huh. crazy.

these are NICE speakers, but far from "top shelf" or "audiophile" quality, and they are only amped via the deck. sooooo... no need for a crazy perfectionist setup.

they sound AWESOME as is... i should know... i run the SAME exact set in my car with a very similar setup, sounds fantastic. if you wanna get technical, the tweeter placement for ALL of us is horrible for soundstaging, but it sure as hell looks cool and sounds better with the windows down..

As curiosity is getting the best of me, but why would the crossover need to be close to the speakers?

[OutToWinPAHC]

I mean do you use two water temp gauges? I read at the exit of the head and then on the cool side of the rad, so I have an idea of how much the temp drop is across the rad.

The reason I ask is I want to know how that N flow performs for you. Because I am considering it, but I am worried about restriction and fluid pressure with the electric waterpump now.

I honestly don't have a good reason/explaination for it. I'm sure some of our audio forum guys would know better, but at the car audio shop I used to always frequent (had many SPL and SQ awards/trophies), they said closer was better for passive crossovers and I seem to recall this advice being on many install guides. I think it has to do with the capacitors and inductors and how they "color" the signal and that longer runs of wires (just a few feet) increase resistance, and can alter the crossover point. This is with passive crossovers since they are b/t the amp and speaker. I dunno though bc I'm not a pro, nor am I an elec. engineer.

lol, well, again I can't back up what I've been told over the years. But it seems you're speaking of electronic crossovers (built into the radio), I'm talking about passive ones. Different systems, one is before amplification (active), one is after (passive). My tweeters are lower than most other S13 installs I've seen. Most manufacturers I'm familiar with recommend the tweeter be as close as possible to the mid, but no more than 8-12inches away. I measured 10" to the center and placed them there (compromised). As you know, if you put the tweeter right by the mid, you lose highs bc they hit your leg, so we put it higher up to "raise" the soundstage, but even at 8-12" phase problems appear. CAr audio, one big compromise. WC knows I wasn't knocking his set-up, just offering my .0002 Also, I really don't know enough to argue the point, esp. with someone who used to do it for a living (you were an installer weren't you?) So, if it sounds good to him, that's fine with me.

I actually used the supplied screws and screwed it to the door. I wanted them to be flush with the door, and the tape would have left a gap. I then cut narrow slits in the door to feed the speaker wire through. In hindsight, I should have drilled individual holes for each wire, would have been much cleaner.

a lot of audio THEORY is theory alone. your boys at that shop have the RIGHT THEORY, but in practicality, NO car is EVER a perfect soundstage.

the points you pose are valid 100% with passive crossovers, however a human being CANNOT discern the difference an extra 2 ft of wiring would make on the speakers "coloring".

working in that industry for 5 years made me fully realize that a lot of shops SELL audio with theory, but can never actually carry it out, due to the fact that cars SUCK for staging. lol

so i gave up on selling on theory and sold/installed with practicality. the majority of people on this earth could not tell you what "sound staging" is, nor know if a system was setup properly for staging.

thus, salesmen who profess all this technical babble to the average joe or to his buddies, is just trying to inflate his e-peen and sound smarter/cooler

[homeslicej2]

gotcha. I guess in top-notch SQ cars for competition it might matter, but for regular use, it's not a big deal. As an aside, what are your thoughts on the Autosound 2000 5 disc set? I don't have an RTA or anything to use all the features of the CD's. I've heard that the CD's are still quite useful for by-ear-tuning. Don't want to get WC's thread to 50 pages too quick or anything but just wondering.

[Didderson]

Finally some good info in this thread

Jeff if she's not gonna run keep on teachin keegs LOL.

[Dizel01]

Soooooooo.....is this thing runnin yet?? I would love to lift my fail stamp on this thread some day.

[hbpignosePA]

i wanted to post the dancing bananna but i cant find it

[White Comet]

no job = no money = no parts = no finished car

[Scuffed_ChukiCoupe]

I hear you on that one. Leave white comet alone!

[Dizel01]

Damn Jeff, I think its time to start robbing banks.

[JRPS13]

hey WC wanna tell me how you got ur blinkers to blink opposite???

[White Comet]

follow adrians_s13's write up

yeah dale, its starting to look that way, i just need a reliable get away car lol

[Idahos13]

Anything new on this man?Looking forward to updates!

[hbpignosePA]

aw

i got excite thinkin the status of this changed.

guess not; we are very much alike in this aspect

[tEknoS13]

x2

[Didderson]

Lol me too.. Jeff I know u gots a job now so it shouldn't be too long til updates, but still weeks..

[OutToWinPAHC]

No job..... just pimp yourself out on craigslist. 20 here 20 there it adds up

[White Comet]

^ hahaha in this economy i'm lucky to get $5 a piece turning tricks. but dont worry, tom is right and i have a job now so this will pick up again. just paid for some cool parts and i hope to have them soon. i had to wait for them to get made so i'm really anxious by now. i'll keep this updated once stuff comes in and i finally get the last few parts

[spooled240]

jeff you have 5 more pages buddy

[idahotuner]

your projects and my are allways continuing and never running lol.

cept mine should be soon.

[idahotuner]

oh and why not be cool and have no radio lol

[cmoody2006]

Whats the latest WC? I haven't been on nico much lately... let alone updated what I've been up 2..... Vert's gettin crazy insane clean!

[mmaxeyjr]

so??.... is this car running yet??....

[mrgreeneyes]

so??.... is this car running yet??....

yeah, its a beast.

[mrgreeneyes]

i may have discovered the ignitor issue.

still a theory, but i found someone with the same issue.....

nissan apparently changed their game up partway thru production of ignitors and pinouts are different
