Fox speaker question

What I'm trying to accomplish , is putting the ford radio/amp back into my car. But the car has aftermarket speakers in it. I was concerned that the ohms in those speakers are going to be too high for the stock amp.
 
higher the ohm the less of a Load on the amp the lower the ohm the more load on the amp so 2 ohm is more power 4 is less of an output and 8 is less then that

the resistance of the speaker coil would be the least of my concerns. What I'd be looking at is whether or not the OEM head unit and amp even put out the RMS power needed to power those aftermarket speakers.

If the speakers you have are OEM replacements then it should be fine. If they are someone's idea of a ghetto rocking upgrade, then the minimum power necessary to support the speakers is probably out the range of the OEM amplifier.
 
It's not 4 ohms because the dash and doors are wired in parallel. Parrallel wiring messes with things a bit. I believe it's 6 ohms for the doors. The dash speakers use a base blocker for low frequencies and that allows for little power to go to the dash speakers

If you decide to use 6 aftermarket speaker, you can use 4 ohms but you need to install base blockers on the dash speakers. I had a thread on this a while back.

I found out from the previous owner of my car, that the only speakers that were changed are the rears. He installed alpine speakers from crutch field. The dash and doors are the stock premium sound. By me putting the stock radio/amp back in, do you think the ohms are compatible on the alpines with the stock football amp?
 
There are two rear speakers depending on the stereo setup. You either get premium or non-premium rear speakers. I *think* the rears are 6ohm but i've never had a set to personally examine.
