I have MB Quart speakers from my old car (4 ohm)

I have heard that its not possible to add anything to a Bose system without changing everything. I would like to install these in the front of my car. Will this cause any issues of will it be a easy install?

I have seen the threads where people have installed the 2 ohm infinity kappas but I already have the MB Quarts so it does not make much sense to go buy new speakers if I don't have to.

Any help would be greatly appreciated.

 

If your MB's are 6.5 components, you can install them, but the sound output will be low because of the 4 ohm rating and you may not like the volume level. So then you will need to replace the Bose amp with another amp (best plan for sound quality) or replace the MB's with 2 ohm speakers (not as good for sound quality).

 

Kind of damned if you do damned if you don't kinda thing I guess..

I really don't want to replace the amp or anything. I had a lot of audio work done to my old car and just don't want to mess with all of that for a long time. I was just hoping I could replace the speakers and call it a day. I guess I could try them out and see how I like it.

If they don't work I could always go with the Infinity kappas like it seems a lot of people do here.

I was also thinking about getting these to replace the 6X9's on the rear deck.. http://mobile.jlaudio.com/products_s...p?series_id=23

 

I don't think those JL's would be a good replacement for the 6x9's if you keep the Bose amp. They are 4 ohms and I don't think the Bose amp has enough power to push them properly.

 

i have the bose system but only the head unit. i swapped out all the speakers. i have a jl cleansweep in my g it runs my 3 sets of a/d/s components and my 13w7. and i can plug my archos in for more music than i can ever think about listenimg to on a drive.

 

Yea but if I wire them in parallel then its a 2ohm load.

What is the power rating of the Bose system?

 

The Bose amp is 225 watts total for 2004. I have not seen the specs as to how that is distributed or at what THD%.

 

How does wiring seperat 4ohm speakers produce a 2ohm load? I thought that would cause problems?! A diagram would be appreciated.

 

^ It is basic electrical math.

parallel wiring -> 4 ohms + 4 ohms = 2 ohms
series -> 4 ohm + 4 ohms = 8 ohms

 

Yes, I've seen it on DVC subs but, I thought doing it with seperate speakers caused a problem with the audio output. Never thought to try it, seems too simple a solution to acutally work.

 

It works just like DVC subs.

 

Ok, so the amp sees a 2ohm load, I'm willing to try that and expecting it to work. But how about the power output/volume? Since you'd have two speakers running off one (of the two) rear channels, wouldn't the volume still be lowered by about 1/2? Or is there a way to compensate for that also?

 

The fact remains that the Bose amp is not very powerful to begin with.
