Audio options

Nice post, LT

. Volvo is confusing in its literature on the audio, and that extends to the sticker specification that comes on the rear window of a new car.

My sticker says HU-613/6 speakers, but there are actually 8 speakers in the car, bass + tweeter in the front doors, bass in the rear passenger doors, and tweeters in the rear pillars.

One thing to consider is that if you get the HU-803 with the center channel speaker in the dash, then you can't have the navigation system in your car as well. They can't both occupy the same space.

Wiz,

FYI-  I did read that the HU-803 is compatible with the nav system... what changes is the size of the speaker- w/nav it is shared in the same compartment- speaker size drops to 4"x6" .  My guess is that the reduced size of the woofer will reduce range and effectiveness of the center channel in PLII , not only that, but the screen will likely be suject to some vibration- so long as it is damped, then great, if not, then you'll hear it rattle a bit... eventually.  Just a guess though, but probably not too far off from reality.

hey - egg on my face -

That a MY2003 thing or is it also true for the '02? (In the '02 the upgrade was an HU-813.)

 I'm sure I read somewhere that the two couldn't live together.

I've researched the Nav Sys w/HU-803 wrt to centre dash speaker. There's no change in speaker dimensions with or without Nav Sys. The speaker grate opening is purposely made large enough to allow the inclusion of the Nav Sys screen option with standard HU-803 speaker.

This makes sense as what caused me to research this was the fact that in my wife's S80 w/HU-801 the centre speaker grate is huge and much larger than the speaker dimensions hidden beneath.

The screens robustness wrt to speaker air compression waves is something to be reckoned with I suppose and hope Volvo has looked into that.

Maybe Hans at FDC will address that issue promptly for me

I stand corrected!  

**barrysharp** · 02-20-2003, 01:29 PM

wiz: I also stand corrected as Low Tide has the correct info. It's true that on the S80 there's no centre speaker dimensional change w/Nav screen but there is on the XC70 as the grate opening is smaller than on the S80 and consequently the XC70 centre speaker dimensions do have to be reduced to accommodate the Nav screen.  

Low Tide's info was confirmed by the XC70 michro fiche diagrams that I had my Parts Dept person review for me. There was no mention of what the reduce speaker size was though -- it's simply indicated as being smaller.

Wiz,

Think of it as "updated" rather than "corrected." I think that the shifting of the audio section of the XC70 is rather funky- and it well could have been the case earlier- or so it was related to you. Armed with the "updated" info we can all make better choices- its just a shame that we have to find the info and double check it in the first place.

Your point is that we have to go digging for it - and you're absolutely right. Volvo have a long way to go in providing their customers with up-to-date, accurate information.
