| I have a Sirius portable radio in my truck and was wondering if it could be connected to the XM antenna in my Azera ('07 Ultimate). I like Sirius more and would like to be able to use it instead.. I would be canceling my XM sub. I know portable XM and Sirius radios use the same antenna connection plug. Thanks | |

Replying to: allmet33 (Sep 12, 2008 5:47 am)  where: 8-16 Driver Speaker 7-15 Passenger Speaker 6-14 Center Speaker 5-13 Left Rear Speaker This information is entirely based on the schematics from hmaservice.com. Yesterday I finally got some time to fiddle around and disconnected the 8-16 wires just to find out that both Driver door speaker and tweeter were then muted. Obviously this set of component speakers are sharing one and the same OUT channel from the infinity amp but what's more interesting is that I measured 2.8ohms impedance at the very same wires which theoretically cannot be matched to whatever combination of 2ohm door speaker with a 4ohm tweeter. I also replaced the center speaker with a 4" coaxial Hertz ECX http://www.hertzaudiovideo.com/default_en.htm in order to add some highs to the front stage, but the installation was not as easy as I expected. The dashboard hole was too wide to hold the new speaker and I had to cut open the plastic grille (remove the plastic grids) and screw it underneath ensuring that the front of the speaker is air tight to the rear sound waves. Allmet33, I noticed that you have removed the plastic ring aroung the OEM door speakers mounted with rivets - please advise how can I remove the rivets and keep the rings in one peace, in case I want to use them for the installation of the aftermarket coaxials (JBL GTO as you have recommended)? Any particular reason to remove the rings completely?

Replying to: megarock (Oct 05, 2008 1:52 am) Not sure exactly how you went about figuring things out. Personally, I contacted the good folks at Infinity's OEM department and they shared everything with me. The tweeter and front lower driver do not share a channel on the amp...the tweeters actually are on one channel, thus...two 4 ohm speakers wired in parallel on that channel provide a 2 ohm impedence. The rest of the speakers in the entire set up are 2 ohm speakers, except for the subwoofer, which has dual 4 ohm voice coils. Again, wired in parallel...making for a 2 ohm load at the amp. Don't know why you had problems replacing the center channel speaker. The Infinity Kappa fits in there with the only problem being the large magnet on the back bumping into the ducting under the dash, but can be offset slightly to work. The original speaker in that location is a 4" speaker.  Why did you cut open the plastic grille to install the center channel??? The grille pops off with only minor effort. The only thing I had to remove was the plastic from the underside of the grille that extends down to meet the oem speaker. What I did to remove the plastic ring that's riveted in...use a drill bit that's a little larger than the hole you see in the head of the rivet and simply drill it out. Once you've drilled all the rivets out...the ring comes off with ease. Removal of the rings is necessary because the speakers are actually built into the rings. The aftermarket speakers you get should have an adapter ring to fit 6.75" openings. I know the Kappas have that, I'm pretty sure the GTO's will as well. |

I just received an email back from the OEM Infinity Dept... "The size of the current center channel is 10cm. While you can use the 4x6 or 5.25 mid-woofers (2 ohm) some of the advantages you might hope to get will be negated by the center channel equalization. There is a 183 Hz high pass and a 7800 Hz low pass filter applied to the 10cm center. Both of your choices will operate down to approximately 80 Hz and out to 16 kHz. You would be throwing a lot of performance away. The Reference 1021T will work in this application provided the recommended capacitor is used." Personally, I feel this would keep the sound the way it is with the voice being dominant in the center speaker, but the music not spreading across the front sound stage. I can tell you, since replacing my center channel with the JBL 4x6" speaker...I've noticed that the front soundstage is much more balanced with music seeming to fill the entire front stage, but the voices are still centered as they should be. As you see, the information also says there would be a loss of performance. Not quite sure what was meant by that because I have not noticed a drop in performance at all. If anything, there's been an increase in listening enjoyment. To me, that's what performance is measured by in the end. Just sharing all I can with everyone, that's all.

Replying to: allmet33 (Oct 06, 2008 10:18 am)  The front imaging became more clear and transparent after the replacement of the center speaker previously characterized as dull. What was meant by loss of performance could be that using a wide range unit for a replacement speaker is irrelevant in this case due to the relatively limited frequency spectrum. Thanks for the shared information, the more we know - the better we utilize the potential of the equipment. I think it makes sense for a central speaker to have primarily vocal frequencies as otherwise the stereo effect will be lost somehow.

Replying to: megarock (Oct 07, 2008 5:35 am) If the sound system were a true surround system, I would agree with it making sense for the sound to be focused on the vocal frequency range. However, it's a music system and that part was ignored. When you're at a concert, if you close your eyes...music fills the entire front stage in front of you...from left to right with no gaps. When you hear the singer's voice, it is centralized (for the most part). This is what the OEM set-up lacks with how they set up the frequency cut offs. With the aftermarket speaker in place, it now allows for a greater frequency range to come through to include the musical along with the vocal, so the sound stage is more complete all the way across, but still centralizing the vocals. The one thing they did get right is the rear speakers are not dominant at all. You really don't know they are playing unless a sound is designed to come from the rear or is you fade them out, then you miss it. I just wish they have paid more attention to the subwoofer and put one in that could handle the lower frequencies a lot better. It's really good down to about 80 Hz, but below that...it really struggles. Thus, that is why I removed it from my set-up. Any bass below 80 Hz with the music turned up caused the sub to distort like crazy and sound awful.

I've always wondered what kind of components they have used for the amp, but unfortunately I cannot tell without dismentling the transistors from the radiator. Here is a pictue with the cover off:

Replying to: allmet33 (Oct 07, 2008 6:05 am) Question .... If the OEM center speaker has a high and low cutoff from the amp how can replacing an upgrade speaker improve the sound.??? I replaced the OEM center speaker with the upgrade Inf. co-ax and did not notice ANY improvement in the sound stage. My Son also said he heard no difference between the OEM and the upgrade speaker ....... Now I know why If your using the OEM amp and IT HAS BUILT IN CUT OFF and can hear the difference then it's called Psycho Acoustics ( If you believe it will sound better it will) That's why many audio company's put all kinds of Bling on their products to make it more Hi Tec looking

Replying to: hjc1 (Nov 09, 2008 12:17 pm) The cut off only controls the frequencies that will reach (or not) the speaker, that's it nothing more. What type of speaker did your son replace the center channel with? If it was a 4 ohm speaker, there's your answer. You hindered the performance of the amp because that would cut in half the power going to the speaker itself. If he used a 2 ohm speaker such as a JBL or Infinity product, him not hearing a difference means he may just not have an ear for it. Then again, I can't say simply changing out the center channel will make that much of a difference if you don't take care of the door speakers as well. All of my speakers up front have been changed, except for the OEM tweeters. The change in sounds is significant, much clearer, definitely cleaner and I can play my music louder without worrying about distortion.
