Bose speakers ???

[kbuskill]

fronts are 1.9 so you need 2ohm and rears are 3.6 so you need 4ohm.

Thank you Captain Obvious..... lol

Ok.... who wants to pull the A-pillar tweeters to see if they have the ohms marked on them???

Anyone..... anyone at all?

I have been looking at replacement speakers and so far I am leaning towards these...

Use these 2 ohm speakers in the front doors to replace the 1.9 ohm Bose.

Use these 3 ohm speakers in the rear doors to replace the 3.6 ohm Bose. And install the tweeters in the A-pillars.

The only thing I am not certain about is the ohm rating of the Bose tweeters and how they are wired. I would think they are parallel with the front door speakers which would also effect the ohms the amp sees.

I also considered leaving the factory tweeter and running these in the rear doors instead.

Any and all opinions welcome.

Any of those numbers make sense, other than the part number?

Those are all good choices,. I like Infinity speakers

No Sir.... that is all I could find in pics online as well.... I guess they are probably not marked.

May have to pull one and check it with a ohm meter..... yes I know it won't be accurate but it is better than nothing.

No worries... I am installing the "dynamat" on the rear doors today so I pulled the rear speakers.

2008 Suburban LTZ non-LUX Bose system...

1.9 ohm front door speakers

3.6 ohm rear door speakers

So looks like 2 ohm front and 4 ohm rear replacements would be in order.

Not sure how 2 ohm speakers in rear would affect the amp or the sound... I would assume the rear speakers would be louder but it may cause the amp to run hotter.

I am going to wait a while and see how sealing/sound deadening the doors is going to improve output... who knows, I may not need to upgrade.

If you have speakers in the very back like the NBS they may be wired in parallel with the rear door speakers. I'm not sure if the NNBS have the C pillar speakers or whatever they're called. Mine are a weird size, I don't remember the specifics.

How's the "dynamat" on the door with road noise?

I came across a post from some forum last night that said the front door and this tweeter were wired together so my understanding is that the tweeter is also about 1.6 ohms so that it and door do not exceed the rear door ohms. Does that make sense? Let me see if I can find it...

Did you check for rear speakers by the hatch? Some people don't even notice they're there.
