Does anyone know the impedance of the various speakers in the 2004 Blose stero? (roadster if it matters)

When I get the roadster I think the first upgrade I want to do is speakers. They are the weakest link in virtually any factory stereo in my experience. But I have heard that Bose uses some non-standard speakers with whacky impedance values.

Also, if anyone has done a speaker upgrade on a bose Z, can you please post what you did ? Thanks.

The Sales Rep at Circuit City told me that that Bose uses all one ohm speakers. He said I would need to get amps and replace all the speakers if I wanted to upgrade. I'm still tring to confirm that.

 

Tis true, unless this Blose is different than any other I've ever heard of. You could do a head unit and speakers, or head unit and amp and speakers. or, you COULD (but I sure wouldn't recommend it is you have any ear for music) keepoing the head unit and doing speaker sna amps using hi-low level converters (or built-into the amp).

And while most speakers do suck, the amp headunit is usually the weakest link; you get the most improvement by starting there. Most distortion you hear is from the amp distorting, not the speakers handling the power. Cheap speakers and good amps will sound better than cheap amps and good speakers.

 

My experience has been the exact opposite. Typically even a cheap amp has much lower distortion numbers than a decent speaker. Most of the pros I know (in the home stereo arena) recommend that a you spend 2X to 3X more on speakers than you do your amp. (these are home stereo numbers).

Maybe cars are different? I don't know. But in my last three cars I have upgraded just the stock speakers to good speakers and the improvement was amazing. Maybe it would have been better if I did the amps/heads, I guess I will never know since the cars are gone.

<<back on topic......>>

For my Z I would really prefer to keep the stock head unit if I can get decent (but not necessarily amazing) sound out of it. I am getting a roadster and a fancy head unit is just ASKING for a break-in. I am guessing that if a crook sees the stock unit he will leave my car alone. Who would steal a Bose?!?!?

So, if I could do upgrades behind the scenes (speakers, amps, whataver) but preserve the head unit I would like to go that route.

 

At least in the 2003 Coupe, the front speakers are 4 ohms and the rears are 30 ohms.

I could never get a definite answer on the sub, but I believe I determined it to be 1 ohm: https://my350z.com/forum/showthread....threadid=25758

As stage one of my Bose removal, I replaced just the 4 speakers with Infinity Kappa's. It sounded much better, but due to the high impedance of the rears, the HU needed to be faded all the way to the front.

I eventually just trashed the entire Bose system: https://my350z.com/forum/showthread....threadid=27990

I've since moved the Baselink to the stock location.
