How do I measure the size of my speakers in my ford ranger? And also how to know what wattage to buy?
Dylan K asked:
I want to buy 4 new speakers for my ‘97 ford ranger to get better sound quality, but i don’t know how to measure them to look for new ones. And my stereo system says 50×4 watts….what does this mean?

The front speakers should be 5 1/4 inches and the rear speakers should be 6×8 inches. The wattage on the speakers refer to how many watts a speaker can hold if you hook an amp up to it. The 50×4 on the head unit means 50 watts at 4 ohms

50 x 4 is a max value for each speaker
the realistic amount of power going to those is more like 20 watts.
you would want to find some speakers with low RMS values(under 50 or so),
and there are many sites to find your speaker sizes.
from crutchfield:
1997 Ford Ranger Pickup
with AM/FM/Cassette deck; with AUTO SET button on factory radio
* Aftermarket Stereo Installed [change]
Factory replacement info:
In-dash stereo
7-1/2″ depth; Size code E,S,U ; Non-standard dash opening (special integration package required)
Front speakers
Front Door: 6×8″
Far rear speakers
Behind Seat: 6×8″
So you need 6×8s or 5×7s
(normally the same thing, or very close to it)
Assuming I set up your truck right.
here’s the link to the thing I used:=%2fapp%2fCar%2fMyCar.aspx
