Stereo Clarification

Just need some clarification on specs of the radio, I searched and couldn't find any straight to the point answers. What is the ohm used in the 03-08 stock Bose system? Also, are the coax. speakers in the door 61/2in.? Would putting in some Alpine coax. speakers increase the sound quality?
Any help appreciated!
 
bump any ideas?

I'm sure someone has got to know.:smile (2):
 
Supposed to be 2 ohm. The doors are 6.5", you just need adapter plates because the Bose is a 3 bolt mount. But the adapter plates are dirt cheap. And yes, the sound does get better when you replace the speakers.

Thanks man! Didn't know I would be needing adapter plates if I go that route.
 
The adapters are like $15 for a pair. It's just really a spacer that bolts to the 3 Bose mounting points in the door and has 4 screw points for most aftermarket speakers. Just look on eBay for any 6.5" Bose adapter for Nissan/Infiniti, very common part. Dash speakers are 3.5" and those are direct drop in, but you have to get shallow ones because the climate control ducts are under there.

I don't beleive the 6.5" door speakers are coaxials, at least they weren't on my 2010 FX. They are midbass speakers, while the dash, center, and rear pillars are 3.5" tweet/midrange speakers. Replacing the door speakers with 2-ohm 6.5" coaxials might sound better, and/or it could mess up your stereo imaging with the 3 dash speakers already producing the high frequencies. If you were going to upgrade anything, you might want to start with the dash speakers. I've heard people that have had good success with either Boston Acoustic or Infiniti 3.5" speakers to replace the stock Bose 3.5 inchers.
 
Ok, thanks! Do I need adapters if I was to get the Boston acoustics ones for the dash? I think after snooping around I stumbled upon them somewhere so I know what you are talking about. Anyone have a link to an installation guide to the ones in the dash? Just would like to see the procedure to see how involved it is.
 
Changing the speakers wont do much. The bose speakers are 2ohm load. The bose speakers are actually pretty good with a different radio. The OEM radio doesn't do it any justice. I changed out my radio and it made a huge difference to the speaker sound.

Yes but to do that you have to cut up a bunch of stuff and make custom mounts right?
 
For me, changing the speakers made a pretty big difference. Everything got a little more clear and there was a lot more detail. It's not noticable while driving (which is why I suppose people like the Bose), but when parked, the difference in sound is very noticable. I thought about putting in an aftermarket head unit, but didn't want to deal with cutting up the dash and then trying to integrate it into the factory setup.

Did you do just the dash speakers or the door speakers? If you did the dash speakers how did you install them?
 
Dash and doors. Dash speakers are easy, the grill pops right out and you can just unscrew them. The only special tool you'll probably need is a right angle screw driver of some kind; the front screws are right by the windshield so not much room. I ordered my speakers from Crutchfield so I also got the harness which made them plug and play; no cutting.

Honestly door speakers are really easy as well. The door panel takes maybe 5 minutes to get off.

Alright, thanks man. Crutchfield doesn't sell the Boston s35's anymore so I have to find them on another site. If you could just show me that harness that you said to make it plug and play that would be great. I also am assuming you replaced all three?

Oh yeah and any worry with these being 4ohm instead of 2? And stupid question, do they sell them in pairs?

My guess is that its not a noticeable difference in sound quality because there isn't much power going to your new speakers. Stock Bose amps are not particularly powerful, and are designed to push efficient 2-ohm Bose speakers. If you were to add an aftermarket amp, I would bet a large sum of money that you could tell a big difference in sound quality when driving.
 
Yeah, I think I am going to try just the speakers first. If I end up enjoying it a lot then I will go to a new aftermarket amp. Stupid question, do they sell the speakers in pairs? If so for 50 bucks I will give it a shot if the 4ohm Boston acoustics will work.
 
They sell most speakers in pairs (2 coaxials, 2 tweets+2midrange, etc.) with the exception of subwoofers of course.
Good luck with your project. Tinkering with your car is half the fun..

Yep its all about getting that perfect setup! I will most likely pick up the Bostons and try them out then. Thanks guys!

So you guys pick up the pair of Bostons and only replace the two speakers on the sides and leave the middle alone?

The Bose speaker system is 2ohms. However the front left and right dash speakers are 4ohm each wired parallel to the 4 ohm left and right door speakers to create a 2ohm load for the front left and right channels. The center channel is 2 ohm, i believe. And the rear door and rear pillar speakers are wired the same as the front channel speakers to create a 2 ohm load for the left and right rear channels. I would use a matching 2ohm speaker component set front and rear to get a better sound using the stock Bose amp and use a matching a coax speaker for the center channel. However, if you are going to use a aftermarker amp then I would use 4 ohm component speakers because they are usually less expensive and have more brand choices. P.S. Do not add 2ohm door speakers to the 4 ohm Bose dash or pillar speakers or vise versa while using the Bose amp, it will create a 1.2 ohm load to the Bose amp, which may shorten the life of the Bose amp due to the higher current load.

Ok thanks for the explanation. Then it is good if I use the 4ohm Bostons.

And to any of you who have installed the Boston s35's. What was the adapter used to make it plug and play and if no adapter was used how did you wire it? Just ordered them and can't wait to throw them on!
