Speaker sizes

VolvoFreak · Post by **VolvoFreak** » 08 Mar 2005, 18:44

I'm finding conflicting information all over the net about this. I want to start replacing the speakers in my car and don't know what sizes to order! I have a '93 850glt with speakers in the dash, front & rear doors and on the rear deck.

Not sure about the dash tweeters. I am thinking 2", the doors are 5 1/4". Back ones are the 6 x 9's. Good Luck.

Sweet.. That's what I thought. Any clue on the depth for the door speakers?

No idea on the depth of door speakers.

Dash takes 7" speakers.

7" on the dash!? Are you sure ('93 850glt)? The grills dont even look big enough for 4" speakers...

I got a pair of 5.25" Kicker's for the front door. They fit perfectly eventhough I needed to drill some holes for the mounting screws as the new speakers didn't line up with the factory holes.

Wow, they are so wrong it's not funny! I pulled the grill earlier and there are maybe 2" tweeters in there, but I think with a bit of coaxing I can get 3.5" in the same hole.

7" tweeters in the dash? That is nuts. They aren't even a third of that.

I heard that I must buy speakers that have 8 ohms for the Volvo 850 not 4 ohms. Is this true?

Yes and no. The front door and dash speakers are 4-ohms. However, the read door and deck speakers are 8-ohms, but are wired in parallel. By doing this, and according to ohms law, by wiring 2 8-ohm loads in parallel, the amp only sees a 4-ohm total load. If you disconnect the rear door speakers, you can put a 4-ohm speaker on the rear deck though.

Code: Select all

Front door left  -----------------> amp
(4 ohms each)
Front door right -----------------> amp


dash left  -----------------------> amp
(4 ohms each)
dash right -----------------------> amp



rear door left  ---
(8 ohms each)      \
rear door right --  \
                  \  \
deck left ---------\--+-----------> amp
(8 ohms each)       \ (4 ohm load)
deck right ----------+------------> amp
