2004 C70 Speaker wiring diagram

[scot850]

I have (with abscates help!) figured out the speakers on a regular 4/5 door P80. Front dash impedance 8 ohm, front doors 8 ohm and then the rear doors + rear parcel shelf/'D' pillar (wagon) are 4 = 4 ohm = 8 ohm. So balanced.

On the C70, the front dash speakers were removed but I am going to guess they are the standard small square tweeter of 8 ohms. The doors (only fronts in the C70) have 2 speakers, a larger one and a smaller one. The smaller one has a label which has 4 ohms on it. The larger one I can't read as the label is faded, but I think it says 4 ohms. So that would be 4 + 4 = 8 ohms?

Then there are the rears side panels which also have 2 speakers per side. I can't read the labels on them but I think they may be 4 + 4 = 8 ohms although I am sure the larger is 8 ohms? This is weird as the head unit is not set up for this.

Does anyone have a wiring diagram for a C70 speaker layout? That car did not have the 2 subs behind the rear seat back.

I have my audio unit test station up and running and have checked out now 5 SC-815/816 units that are fully operational from bulbs to CD player, cassette player and radio! Now I want to test all the rest of my spare audio stuff to make sure they are good to pass on. I still have many amp link cables, amplifiers and more head units and speakers to test!

Thanks,

Neil.

Oops!! I totally forgot you sent that to me a while back! Many thanks for the reminder.

I know you sent a link with the items on it to identify them by number ID. I can figure many of them but not all in terms of their function?

two other questions.

1) I did not realize that the speakers used cross over units so did not pull them. I could not see them when I was working on the car so goodness knows where they are! Car is junked now so too late. I am assuming I can fit the speakers into my test rig in place of one of the corresponding speakers with the same impedance for testing purposes? They may not work as well but should be good enough to identify they are good??

2) The drawing has 14 !! speakers as far as I can tell. The car only had 10 that I know of, maybe 11 but the dash top was missing so I do not know if it had Dolby center speaker (so possibly 11?).

The drawing has 2 speakers at the front marked 16/26. Not sure what these are? Are they the small dash side speakers?

Or are any of the 6 in the middle of the drawing the 2 dash speakers (16/7 and 16/8 marked HI) I was thinking that 16/29-32 are the 2 door speakers possibly?

The rear has 6 speakers working on a pair of cross-over filters. I'm thinking that may be the 2 rear side speakers and possibly the 2 rear subs if chosen as an option? (16/43 + 16/44)?

Any help/guidance appreciated as always!
