#3479 of 4353 Kill Overspeed Alarm

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.

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.!!

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!

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 !

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.

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.

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.

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.
