Pontiac GTO



  • Good try, elias, but just like privetotruski said 'cracovian' is Polish. It refers to the beautiful city of Cracow where, as the matter of fact, one of Spielberg's movies was shot, however, it was "Schindler's List" and not "The Terminal". He must have gotten inspired by that name though when he invented the fictional country of Krakozia (sp?)

    My brother almost imported the '04 Goat to Warsaw (the price then was sooo good) but he ended up with the Honda Pilot instead. Good for him; he'd be in big trouble now - he's much taller than I am ;-) He would probably have to get the part from Britain where they're sold as Vauxhall Monaros...
  • Got a question... I have read a lot about people upping the horses on their GTO's, can anyone tell me what kind of power the drive train can safely handle? I have been planning on various power upgrade to my '05 but I'd hate to do that and find the rest of the drive train can't handle the engine. :sick:
  • I thought I had seen posted here that some folks upgraded their stereo speakers. I just turned over 1,000 miles and I'm beginning to think my speakers/sound quality from my 02 Bonneville had better overall sound. For some reason i just don't think the factory speakers have enough overall depth. The bass is not all that good either. Has anyone changed out their factory speakers and has the quality (and bass level) improved with after market speakers? Did you change all speakers or which ones should I focus on replacing for the best effect? I would like to try this change-over myself, but would likely have a professional audio store do it.

    Robert pointed out about 3 pages ago that you can change the output on your stock sound system. I did and it made a large difference.
    OPen the boot, trunk.. peel back the laeft wall of carpet... on a metal plate between the gas tank and the fender is the amp for the system. REach around and you will feel the output nob. Turn it up or to what ever level you like. From stock its really low.

    First post, although I relied heavily on you guys in my decision to get the Goat. 2005 Phantom Black on Black M6, had it for a week. Hands down the best car I've ever owned. The local dealer got a glut of 05's (six, which constitues a "glut" around here) delivered in a two week span in August. Gas is $3.00 a gallon, he's got six GTOs (two sat on the back lot in their styrofoam and protective shipping materials) and the 06's are right around the corner. I figure they're ripe for a deal. I guess the mark-up is low because they weren't real enthusiastic at first. My buddy works at the dealership in the body shop. Apparently they'd just had a meeting about how crappy their numbers were for August, and September was looking disappointing as well. (Damn! If only they'd had more Azteks!)
    Anyway, he suggested timing my strike as near month end as possible, since that's when the sales pressure really ramps up. It was tough because the black M6 sitting on the back lot unprepped was the only one I was really jazzed about and I was afraid it would be gone. The end of September rolls around and doesn't GM put the Employee Pricing on the remaining 05 GTOs? I got the employee pricing and a $1,000 dealer cash, brought the price down to $29k.
    The forum is great. I've already done the sub amp tweak (very cool) and ordered the replacement Goldwood subs as suggested by Robert. I'll be upgrading the door and rear panel speakers next week. I did have XM added using an XM Commander unit. The control module fits perfectly in the little storage unit below the head unit, but it wasn't possible to recess it enough to be able to close the door. The appearance of the control unit ties in nicely with the car's black-and-silver interior appointments. Ditto with the Escort Solo 2 cordless radar detector, which also eliminates the issue with the lack of a dash mounted 12v receptacle.
    XM has its own unique compression characteristic that tends to sound "boxy" if there isn't a direct connection to the amp (RCA or a cassette shell adapter). With the Blaupunkt the only option was FM modulation. The XM Commander physically jacks into the antenna input rather than relying on over-the-air modulation, however there is still a marked loss of highs and separation. I'm hoping replacing the door speakers with high grade aftermarket gear will help. Note that the XM unit will step on your regular FM stations, so turn it off if you want regular on air radio (but why would ya?)
    With regard to removing the head unit, the tool is handy (Circuit City sells them for $20, in my case the Pontiac dealer loaned us theirs). As far as requiring re-coding, we had the head unit out of the car entirely for several hours, and when re reconnected it, not only did it function fine, but it still retained its settings (except for the clock).
    My question is, how do you disable that goofy "overspeed" indicator? I've run through the set up screens and I think I'm selecting "No" for overspeed, but the damn thing goes off just when I'm about to "get busy". Thanks again.
  • ausstarausstar Posts: 21
    Whats up mate. As far as I have experienced you can;t turn the bloddy thing off. If you go to the display that has the overspeed setting you can just turn it up as high as you want. I dont usually go more than 100 m/hr so that is what I have mine set to.
    On another note... Robert if you are reading this I was wondering if you have had any problems with the trunk release buttons. Sometimes mine works but most of the time I have to get out and hold the lid up and press the remote button at the same time. Fricken annoying cos I dont want to have to turn the car off every time I want to open the boot. I know the Aussie Monaro's dont have this problem I think this is just my car. The dealership does not have a clue how to fix it.!!
  • mick1mick1 Posts: 84
    The car must be in park to turn it off. I had the same problem it was driving me just as crazy playing with the buttons while driving. On the other hand maybe the car is trying to tell us GTO guys to slow down a little!
  • eliaselias Posts: 1,828
    on the aussie rear lower bumper/cover. the part i got is unfinished black. in photos of the aussie version they seem to be similar/dark grey to what it has on the GM USA part. i'm not sure i'm going to like the black lower bumper. i think i want it painted body color. maybe i'll try it in the flat black for a while and get it painted later. dunno. what are your thoughts on the whole thang ya bottler !
  • kbobe67kbobe67 Posts: 23
    Somehow I got it to turn off. I had just refueled and press the "set" button to reset the fuel stuff, and now in the left screen it reads "Overspeed: OFF". No idea how I did it.

    On another matter, I'm thinking of replacing the stock front speakers with components. Has anybody had success finding an appropriate mounting location on the upper door for the tweeter? There's a little triangular plastic piece that trims out the inside of the side rear-view mirrors that looks promising. Any thoughts would be appreciated.
  • jontyreesjontyrees Posts: 159
    If you do go with components for the front, try to get the highest efficiency drivers you can find. The stock head unit doesn't have a whole lot of output, and you may find yourself lacking volume, or cranking it up to distortion levels. I replaced the stock speakers with some middling Blaupunkt coaxials, and after some tweaking of bass/treble and the sub amp, it sounds pretty good. I definitely have to turn the volume on the HU way higher than before though, (around 40-45 for fairly loud, whereas 35-40 did it for the stock speakers). As a huge generality, cheaper drivers tend to have higher efficiency and are easier to drive than high end stuff, (eg an Infinity Reference speaker tends to offer a dB or two higher efficiency than an equivalent sized Infinity Kappa - the more expensive line).

    'Coure, you could add an amp.
  • jontyreesjontyrees Posts: 159
    OK - bad example on the Infinity speakers - I just checked Crutchfield, and it seems that the Kappas are now incredibly efficient, even more so than the Reference. The generality still held for other brands, eg Polk. Get some Kappas!
  • I see that GM sold only 994 GTOs during September even with Employee Pricing for Everyone in place. So in 9 months this year they have broken the 1K per month sales mark 4 times, including the leftover '04s they're were unloading during the first few months at $5K off msrp.

    Will there be an '08 with this kind of sales performance?

    Thin paper vs the thicker, beefier, more durable, higher power handling speakers. In general, a speaker with a higher power handling will have a lower sensitivity.
  • kevm14kevm14 Posts: 423
    I bet if you plugged in the T-S parameters for each, the references would still be more efficient. I've seen a lot of bogus efficiencies for speakers that just shouldn't be able to be that sensitive. Surprise, they're not.

    Well, today at Circuit City the install guys peered into those little louvered spaces on the dash at the a-pillars and determined that there were factory tweeters in there. I'm still trying to figure out how its a 10 speaker system. Presuming there are tweeters in the dash, that's two. Two 6.5" in the doors, two more in the rear side panels, that's six. The two subs in the deck, I get eight total. What am I missing?

    I did some listening tests for the front components and liked the MTX units best. They seemed warmer and less brassy than the Polk or Infiniti. Not sure about their relative efficiency but I'm gambling I can get by without and amp. MTX are on sale for $179, plus if you buy a second set (like their 6.5 coaxial for the rear sides) they're half off (or $35). That's $215 for the full compliment of door and rear panel drivers.

    Anyway, I took Robert's suggestion and ordered two replacement subs from Parts Direct. The units he suggested were 8 ohm. I upgraded a little to their "heavy duty" 8 ohm drivers. However today the installers put an ohm meter to the factory subs and read 1 ohm of resistance on each. They're concerned anything greater will eventually cause the sub amp to fail. Anybody have any experience with these? I guess I'll wait till the replacement subs arrive and determine if an upgraded sub amp is in order.

    As an aside, I've been whipping up on the Mustang and Subaru guys on their respective comparo forums.

    It's interesting how the GTO, (which virtually every performance enthusiast who doesn't own one hates) so often serves as the "benchmark" car for everyone elses' comparison tests, in which it always narrowly loses. The thing is, the Mustang and Subaru guys seem to have a lot to say about the GTO. For some reason the car's very existence really gets under their skin. On the other hand, I'd guess most GTO guys couldn't care less about any other car, with the exception of what's in store for the 2007 GTO.

    Seriously. I think we give about as much thought to other cars as Evil Knievel gave to the specs of the semi trucks he jumped over.

    Maybe the rear speakers are coaxial.

    That's interesting, I chose Polk over other brands for my Camaro because of the silk dome tweeters. FX6.

    However today the installers put an ohm meter to the factory subs and read 1 ohm of resistance on each. They're concerned anything greater will eventually cause the sub amp to fail.

    Wow, 1-ohm. Sounds like the factory wanted to get by with less amp or something. No wonder why it sounds so bad when you crank it up, the amp must be putting out a pretty gross signal, on top of the flimsy speakers.
    I'm an EE and I don't see how going to a higher impedence is going to hurt the amp. It should draw far less current than the stock speaker, which will make the amp run cooler, but you'll need to dial in that much more gain to get the same output as before and maximum output will also be lower. Perhaps a sub upgrade is in order.
  • There will be no 2007. Robert (the answer man) has covered that one more than once already.

    "The current model GTO will stop production no later than August of next year, maybe sooner (its Monaro counterpart ends production at the end of December). It can't be continued in North America because it doesn't meet 2007 MY crash standards."

    Sorry to interrupt the smiling, happy people feeling around here but if GM doesn't stop bleeding red ink the 2008 is done as well. No $$ and/or time to spare to develop it.
  • kbobe67kbobe67 Posts: 23
    Smiling, happy people? You have us confused with the Prius discussion board. Ok, so it'll be a 2008 GTO. Or not. I have news for ya, GM has been more or less sucking wind for the past two decades. They still manage to put out new models every few years. I guess we better take really good care of the ones we have, just in case.
  • kevm14kevm14 Posts: 423
    What do you think I'm doing with my 93 and 95? They abandoned BOTH of my cars' platforms. All I'm missing is a Grand National and a Fiero.
  • kbobe67kbobe67 Posts: 23
    The Fiero's back. I think they call it the "Solstice" now.
