Bose speakers ???

[kbuskill]

I have a 2008 Suburban LTZ with the standard Bose system not the LUX Bose system.

Can anyone verify with 100% certainty if all 4 door speakers are 1.9 ohm... essentially 2 ohm?

I have looked but cannot seem to find hard facts.

I am thinking of upgrading the speakers but I am also lazy and didn't want to pull door panels and speakers just to check.

I know someone here surely has the answer.

Also does anyone know the wattage rating of the non LUX Bose amp?

I am trying to find some decent speakers that won't break the bank but I really don't know what ohms and wattage to look for.

Feel free to make recommendations. I have read that coaxials are good for the rear doors but to use components for the front.

Thanks in advance.

I was looking on ebay at stock speakers and it looks like 1.9 ohm front and 8 ohm rear.... seems weird.... hopefully someone has a set they removed sitting on a shelf and can verify.

Do you have part numbers for your original speakers Ken? Research for my truck, and I think we have the same system, says the rear door speakers are PN# 15186669 and those are 3.6 OHMS. My front door speakers are PN# 15905042 and they are 1.9 OHMS.

I like the sound and in a year or so will change them all out for new factory ones. I've never had such a powerful stereo system in my cars. I thought it cool that it gets louder and louder without distortion unlike our previous autos or even our old stereo system at home.

I would have to pull the door panels and speakers in order to get the part numbers and like I said.... I'm lazy... lol

I see so much conflicting information when I look at stock speakers on EBay.... not that EBay should be a trusted source for information but sometimes it works.

I see listings for Silverados, Sierras, Tahoes, Surburbans.... front and rear speakers with pics of the speakers and some are 1.9, 3.6, 4, 8, 12.5 ohm..... I think I may end up just having to pull them and verify.

Maybe I will just try sound deadening the doors and keeping the stock speakers for a while.

There is nothing wrong with my speakers but I thought since adding the sub it would be good to upgrade the rest of the speakers as well.

Did you run your VIN through GMPartsDirect and get the numbers? My part numbers came from there and then to answer your question I looked at images on google, folks showing backside of speaker with sticker which included the part number and showed the ohms. I have them all saved on Amazon too but so far they all work to our satisfaction. I can barely hear anyway anymore, damn tinnitus, an F-4 Phantom running in my ears all day long.

My daughter and I are supposed to be replacing the interior door handles next week. If we do, I'll see about confirming the part numbers while the panels are off.

Hadn't thought about running the vin to figure it out... I may give that a try later on today.

Thanks for the help.

This is helpful for another thread I created to see if you could run aftermarket amp on stock speakers. 2 ohm in front and 4 ohm in rear sounds interesting if this were the case. Fronts would then get louder if connected the same way. A good 4 channel 4 ohm amp would probably do wonders. Fronts can run @ 2 ohm and backs at 4 ohm.

My only concern with this would be that it could potentially cause the amp to overheat on the channels running at 2 ohms or it may induce clipping.

Most amps can run 4 and 2 ohm but not sure you can dedicate 1 channel to 4 ohm and another to 2. This is what I was hoping was possible to avoid the concerns you just listed.

I can confirm the front door speakers in my 2008 Suburban LTZ with the non-LUX Bose amp are indeed 1.9 ohm.... I will update this again after I pull the rear speakers and check.

I installed Infinity Kappa's 62.11i's in my front doors,.. mated with a Kenwood DDX and stock Bose amp,.. a huge improvement over stock sound.

Thanks for the info... I have been looking at upgrading the speakers and have heard good things about the Kappas... there is nothing wrong with my stock speakers at this point so I decided to sound deaden first and perhaps I will upgrade later.

Before...

After...

Still need to do the rear doors.

Looks good,.. where do you get the sound deadening material ?

I actually got it from my brother. He bought it for another project and never used it. I know he got it on eBay but not sure on brand or price.

Those Kappa's are 2 ohm speakers so they will get the most out of the stock amp and it seems they dont require much power to do well. If a 4 ohm was put in their place, I'm assuming thats half the power they will get from stock amp. It sounds like if we are planning to keep stock amp for a little while, we would get most out of 2 ohm speakers rather than 4 ohm.

Since you have aftermarket HU and probably puts out more power than stock amp?, I guess we would be winning if the 4 ohm was connected directly to HU rather than amp? You tried connecting those speakers directly to HU instead of stock amp? I hear the stock bose dont put out much power but they are super efficient and mate well with the bose speakers.

Sorry Ken, my daughter did the door handles for me yesterday while I was/am sick and forgot to ask her to check the numbers.

I have not,... but now you have me wondering...... I was assuming that the Bose put out more power than the HU, thats why I chose to do it that way, Also, it would take some creative portioning to do that because my entire system goes through a series of interfaces (2) in order to retain factory chimes, phone capabilities, Steering wheel controls, ect.... But thats an interesting point.... I wonder if I just did the from Kappa's direct from the HU and leave all else through factory if there would be an improvement. Does anyone know what the factory Bose puts out for wattage ?

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.

Before...

After...

Thanks for the feedback. I am planning to get front speakers first and run directly to aftermarket HU. I hear stock amp is very efficient but super low power. I'm curious to know numbers as well because if it will get louder on stock amp, i rather go that route too until I get amps.

I also want to hook up aftermarket sub to stock amp. I know it will be very underpowered but I already have sub would like to use it while waiting. Anyone know power goes into sub and what ohm the stock sub is?

fronts are 1.9 so you need 2ohm and rears are 3.6 so you need 4ohm. Your stock bose amp wont last long if you run 2ohm rears.
