Does this look like the original front speaker from '89?
what ohm are these?

 

they look original-8832 date code is 32nd week of 1988, these are usually 10 ohm,sometimes 4 ohm.

 

I've seen Japan around here. My1990 factories were from Singapore and say Delco Electronics. https://www.thirdgen.org/forums/elec...ml#post6330536

 

Yup,..... Those fronts should be 10 OHM.




( 4 OHM 4x6s were only used in Pontiac F-Bodys as part of the UQ7 subwoofer system & mounted in the REAR speakers boxes. Those cars also used 4x6 10 OHM in front too like all other F-Bodys. )

 

Ok, 10 ohm.
Here are the rear 6x9. Again I assume original and obviously 10 ohm.



Here is the original radio (as far as I know)



I had M&R rebuild it and add the aux cable.
Looking through Crutchfield catalog, I only see 4ohm replacements. What do you guys think about using 4 ohm instead of 10?

 

Don't do it: ( watch the video )

Edit: Factory head unit can power 1 4-OHM and 1 10-OHM on each channel (L-or-R). Some/Most Pontiacs used 4 OHM rear 6x9's. Connecting 2 4-OHM speakers to 1 side (L or R) side is not advised.

 

hmm, I cant see the video but I see what youre saying in the other thread.
bummer

 

I understand why the link doesn't work by simply clicking it; Site doesn't seem to want to redirect to an 'outside' website ? It used to work by just clicking the link, but not anymore. However: If you cut/paste the web into your browser,... you can watch it.
