Ladies and Gents,

I own a 2006 G35 sedan with a factory Infiniti (NON-BOSE) radio. I am looking for information on the OEM system itself. Particularly:

1. Who makes the infiniti OEM radios?

2. Who makes the speakers?

3. Do the front speakers have a built in crossover (since they appear to be component speakers)?

4. Does the radio have a built-in amp or a small external amp?

5. What is the power rating (i.e. 20 watts x 4 channels) of the radio and/or amp?

6. Does the car have a subwoofer anywhere in it (probably not, but I thought i'd ask anyway)?

The reason for all my questions is that I am interested in upgrading the stereo system. The factory radio is actually not bad and I want to make sure that I improve the sound, not degrade it. Answers to the above information would allow me to do good comparisons when shopping for components.

Thanks for reading and any responses would be appreciated.

 

3. The front speakers have full signal to the woofers. The tweeters are spliced into that signal and have a small resistor that, I think, acts like a HP filter.

4. The base stereo has a built-in amp, not an external one.

6. No sub in the base system.

I don't know the answers to the other questions. Good luck!

Thanks to you both for the answers to my questions.

I will advise on what I end up doing with the audio system.

Thanks again!!!

 

Upgrading the head unit did wonders for the sound quality in my wife's 06 sedan. You start there and move up as you go.

 

Old thread, but what component speakers did you end up going with, and did you install a crossover for it? The passenger speaker died on my coupe and I want to find out what I need to do after I take off the door panel. I'm just looking for a straight swap, dont want to replace any other parts for now.

Thanks!

 

Any decent component speaker system has a crossover as part of it.

Hit up Crutchfield.com and punch in your car info and browse what's available. They include all the necessary adapters to make it as simple as possible.

As for recommendations on which components to get, list your budget and you'll get recommendations.

 

Vehicle is an 05 coupe with the non-bose system, all stock.

Ok, checked Crutchfield and if I'm understanding correctly, I just need to attach the previous woofer wires to the crossover input, and then attach new wires from the crossover output to the woofer, and wires from the tweeter to the crossover as well. If I order from Crutch, the woofer adapters are included, but if I don't, then I need to purchase or make adapters (like the zenclosures). I need to also seal off the front of the speaker to the grill, to improve the bass, from what I've read. Seems easy enough....

As for my budget, preferably would like to stick to under $100. Even tho these are out of my price range, I have seen the CTX65CS - Image Dynamics 6.5" Component Speaker System is well regarded on this site, so I will look to see if I can find any deals online and spend a few extra bucks.

I don't mind 2 way speakers if that would help get a little more quality for the price range I have. Thanks for all the help!

 

I'd keep saving. $100 replacements will be better than stock, but for all the trouble of installing, you might as well do it only once.

If you're going broke replacing a stereo, your priorities are all wrong.

 

Dartmouth01,

For the front of the car, I went with a set of Alpine SPS-600C (C is the Alpine designation for component.) For the rear doors I went with a pair of Alpine SPS 600 (Full Range.) The components are set up by Alpine so that the larger speaker has a built in crossover (attached to the speaker itself) and the tweeter comes with an in-line crossover (which is thin and long, but easy to hind behind the door.) I ended up installing the Tweeters on the front door just above and slightly forward of the door handle. All I used was a forstner bit in the appropriate size and then installed it (as the two tweeter parts screw into each other.) I left the factory tweeters in their original opening (no reason to move them.) I just made sure to cut the cables going to factory tweeters, so I could use them for the new tweeters. The large component speakers and the rear speakers all fit in the factory opening (although barely managing to cover the entire opening and I had to drill new holes for the mounting bracket screws.)

The benefit to these speakers was that I did not have to find a location in which to mount a “traditional” crossover. I got them for less than a $100 bucks on-line. However, they don't reproduce bass very well, so if you need some low end punch, you will need to look for something a little better or add a subwoofer (I did the latter and am very pleased - 10" Polk db1040DVC wired in parallel to draw 2 ohms out of the Kenwood KAC-6104D). In the end, they installation went pretty smoothly and turned out all right for an amateur. Hope this helps.

 

Red, thanks for the writeup. I ended up ordering the Image Dynamics speakers for the fronts, and the zenclosure spacers. I'm leaving the rears alone for the time being. I dont know yet how I'll mount the tweeters, but I was hoping they'd fit in the stock space, so i can keep the stock look as much as possible. I'm not sure where I'll mount the crossover either, but I suppose I'll find out when I have all the pieces and the door apart. :-)

The only thing I think I'm missing now is dynamat. I've never done this before but I figure it should be fairly straightforward. However, what I don't know is how much I'll need to cover both coupe doors.... suggestions? Also, where is the best place to get it? Online, or local install shop (since its pretty heavy, if I'm not mistaken?). Thanks!

 

dartmouth01,

Sounds like you are good to go. As for the dynamat, I did not use any (cause I'm sorta cheap) and that would have meant more time working on the car. Unfortunately, time is a precious commodity in my household, so I snuck in the stereo work when I could.

The stock tweeter location is not very roomy, but if you are ingenious, you can figure out a way. If not, I can take a photo of my tweeters on the door and you can see if that is a location you would be cool with. Lots of room behind the door panel to install those crossovers, so don't worry too much.

Have fun with the install.
