Quote from S14 DRIFT :

Diesel fuel requires compression to combust in a car, now I'm not a scientist and I can't be bothered to be, but from reading online the combustion temps in a diesel engine cylinder are more like 350 degrees which is above the autoignition point of diesel which is like 210..

question, if you hold a match to diesel and it reaches 350 degrees, thats when it will ignite from spark?
if you give it enough compression for it to reach 210 degrees then it will ignite without spark?

am i using the terms right? backwards?

i completely understand how a diesel engine works, compared to a gas engine, but this part is throwing me off a bit.

those were great

i dont usually post in this thread, but those are worthy of praise

EDIT: most are worthy of praise, but i dont know what to look for in a 'great photo' compared to a 'good photo', those just got my attention.

not for me

it has been able to snow temperature wise, just hasn't here..

i would like on paper, it could cut back on cost, and ease to ship. you could sell many more cause it is overall less.

i might be a minority here

i think he means using LFSTweak

i would buy it

looks like i crossed into its natural habitat and startled it.

that is a little lame....

Me and my brother took a spin after work/school. It's all I could get...the title is not ours yet for the gto, and mine needs a stabilizer link before it is mine; they are both at the dealership; much better pictures to come.

shot with a shoe.

its pronounced toaster

my first car

This is my first ever car, first ever bmw

1) Model Year, 1999
2) Model Number (528iT....), 528i
3) Design generation (E21, E34....), e39
4) Color (official, if known), black (not sure official)
5) Major options, fully loaded, 5 speed, dsp, business class
6) Modifications, none yet..soon cdv delete
7) Use: beater, track car, show car...., daily driver, soon a little of all 3
8) Awards or Accomplishments, its pimp
9) Ownership history, when did you buy it, etc.... purchased about 4 days ago, pictures finally..

my brothers day-after-purchase is the gto next to it; its a 6 speed ls2 with 400+ hp.

im so happy





sorry for bad pictures

also; the gto next to it is my brothers 6 speed, ls2 with 400+ hp

this is it!

my first car; my first bmw; my first love

its a 1999 528i, e39

needs essentially nothing, its a manual, with basically power everything.

questions? comments?





shittiest pictures, camera phone :/

my brothers day-after-purchase (the gto) is next to it. both black on black, his is a 6 speed ls2 with 400+ hp

im fine with tattoos, personally...they just cant be over done.

a well thought-out, non impulsive, reasonably sized tattoo (almost anywhere) can be fine in my opinion. they could be almost anywhere to conceal, or just cause it fits there well.

same goes with piercings; snakebites/spiderbites can look great. if done right, they dont nessecarily make you look like a rebel/drug user/etc. adds a little edge to your looks, its all how you highlight it imo.

my two cents, maybe worded a little wrong.

cheers lynce, take your time; everybody is at this point

HAPPY BIRTHDAY SCAWEN!

enjoy it, take the day off, take your mind off. Spend it with the family.

my dad will know how to wire them if i give him the spec's. im clueless with electrical, except for a simple outlet, or switch.

i am bound to take a trip to the audio experts in my area at some point, i guess..

each description of a ported vs. sealed box i want to change what i want...il figure it out eventually

i cant just wire the sub's parallel? will that work?

also, the dsp basically just makes the amp that comes with the car incompatable with everything else; my head unit's display is not working, and i want to be able to use my ipod. for this combo, it is easiest to just replace everything.

it has the 4x50W power outputs, but i cant find if it has the crossover...any idea jakg?


EDIT: and im rebuilding the whole audio system because i have to. the DSP radio it comes with wont allow it any other way without other modifying. so it isn't a question of the system being up to it, but a question of buying the right stuff.

one last hassle with you, i hope

this is the updated, and perhaps final list of whatever.

what do you recommend as a change? what do you recommend i go on ebay/amazon for to find cheaper.

Quote from Jakg :

Thats a "how long is a peice of string" question, that only you can answer.... I've used ~20m for my door speakers, but then I've run dedicated wires from all the doors into the boot. It depends what your wiring up, from where to where, the route etc. But at the end of the day - cable is cheap. You will always find a use for the spare stuff.

I notice you've also not bought any power wire / accessories...
Obviously you have different brands in the US, but looking through Crutchfield...

Alpine - ok,
Boston - older speakers were good, none of their new stuff is brilliant,
Diamond - good,
Focal - very good (although expensive),
Infinity - ok(ish),
JBL - good (...if your on a budget),
JL Audio - good (but quite expensive),
JVC - avoid,
Kenwood - ok(ish...),
Kicker - good
MTX - good,
Pioneer - nothing special,
Rockford Fosgate - good,
Sony - dont bother.

Avoid the Chinese stuff like the plague.

A ported box gives more output, but not at all volumes - it will be tuned to a specific frequency, and anything above or below that isn't going to be that loud.

I built a ported box, and it kicks like nothing else on the lows... but as you start to bring the frequency up, you start to lose alot of the output, and so you don't really get any bass.

Plus, a ported box is harder to build, has to be much closer to the right size to sound good, plus is always going to be larger etc... my next box will be sealed for sure.

At the end of the day it's personal preference - but you cant just slap a speaker in any old box and expect it to sound good.
This is probably the last place I would ask for car-audio advice tbh...

Try somewhere like here - http://www.stevemeadedesigns.com/board/

ok, i think i got this...just a recap to make sure..

for the wire, just take my own measurements, and add a few feet for comfort room?

doesn't this cover the "power-wire/accessories"? http://www.crutchfield.com/S-P ... Amplifier-Wiring-Kit.html



half of those brands i dont even think i considered on crutchfield; shouldnt have a problem there. il revise my list to make sure anyways.

dont plan on buying anything that i dont know the name.



if i can fit it, i will get ported i think. i will measure to make sure, obviously. my dad is great with measurements and he can help me with that.



when i figure out the main issues i am having, with the dsp etc, i will be sure to check out that forum.

thank you guys for your knowledge

Quote from Jakg :

The amp is rubbish - Sony's amps havent been any good for the last 10 years, and $200 for 600w RMS is rubbish.

what do you recommend, that will still not kill my budget, sound, or speakers? i prefer ordering from crutchfield; free shipping, lifetime support, 30 day guarantee, generally cheaper then other places, etc.

Quote :

Your speaker wire looks pretty expensive - I can get 10m (~33 feet) of 2.5mm² (13 AWG) speaker cable on eBay for around £5 (~$8).

i wasn't too woried about a few cents for a foot, but i guess i should check ebay for something as cheap as wire

how long should i need in total?

Quote :

DO NOT BUY A PREMADE PORTED BOX! I cannot stress this enough! A ported box has to be designed specifically for the sub your using - i.e. the main chamber must be the right size, and the port must be the right size (volume / length) for the particular sub you want to use, or it will sound rubbish. I would start with a sealed box, as it's the easiest to make (so if you buy a premade one chances are it's going to be ok), and if it's not quite the right size it won't sound shit. Also, a lot of people don't like the sound of ported boxes (me included - I spent several days making the perfect box only to find out I hate the things!)

this is where everything is going to get tricky. i heard a sealed box versus a ported box delivers cleaner, deeper bass. If im better off making a box, then good; im not too sure where to turn for a box though because of hearing mixed things.

Quote :

The subs look... ok, but nothing to write home about. Pioneers speakers are nothing special... for value bass, JBL GT5's get good reviews and can take a load of power.

the biggest thing is my budget. nothing is set in stone for anything. I want somthing that will be the best bang, and that will stay under 75-100$. I dont need anything brand new, or extra thin; just something that will sound good.

Quote :

No chance you could get some decent component speakers?

speakers are the least final thing im looking at. I need something that will fit with no modification; im not sure what the dsp radio has to do with this, but its confusing me.

Quote :

FWIW - you DONT need to match up the amp / speaker power perfectly. If your amp doesn't deliver enough power, when you drive it too hard you'll get distortion and then clipping which will kill the speakers. If you've got too much power, obviously you'll blow the speakers if you turn it up too much, but as long as your careful you'll get loads of headroom which means loads of clean power when your giving the speakers enough power. Most of my amps deliver 2x the rated power of the speakers.

how close do i have to get to the power ratings? obviously the closer the better, but i dont want to take chances with my volume knob; especially if i lend it out.


im probably going to create a seperate thread here, but not until i feel i have to.

thank you, guys.

well it started off with that being my main concern, then i realized the dsp will make everything complicated; i didn't feel like flooding you with questions you may or may not want to answer, i figured i would toss the link out there, and if anyone wanted to pick a question to answer, they could...but now im kinda stuck because i need to know what to ask for for christmas (keep in mind i am only 16 :tilt.

my main concerns right now are if i buy all of that, it will either not be compatible, or not fit.

If i go to one of the audio 'experts' around here;
A. i feel like they wont know car specific, but more just how to 'make it work', through modifying, or just through knowing how it all works.
B. as a business, they will probably pressure me into buying something of theirs, or if i already have the stuff (which i just need to know if it will work before i buy it), they will want me to have them do the work. I would have them do the work if i knew they wouldnt hack it together, or if me and my dad couldnt do it ourselves after knowing what we are doing.

EDIT: and yeah, i copied and pasted from the first post, and i think the forum there shortened the links, so the copied links were wrong..
