I'd like to just replace the factory amp with another one, but I'm having a hard time finding one. I found one on ebay and ordered it, but they shipped a different part # and refunded my money when I asked them if they had the correct part so now I'm back to square one.

Does anyone know of a good place to track one down or has anyone upraded their sub setup and want to get rid of their stock amp?

If I can't track down the factory amp, is there anything special I need to know about installing an eftermarket one? Ohms requirements, x-over frequency, etc.?

I'm happy with the stock sound and I'd like to fix this as cheaply as possible...

 

Besides ebay or a dealer(who would rape you cost wise) I really cant think of anywhere. There are a couple places on the internet that sell factory Ford parts, such as Tasca, but I dont know if they would have something like that or not.

 

if stock is good enough, you could probably find an 8 or 6 incher with an amp and everything you need for like 150 i would guess.
just get something that would fit where the stock one went

 

oh, didnt read that its just the amp

would it be possible to wire a cheapo aftermarket amp into the stock wiring?
i bet you could do that...you probably only need 100 watts or less

 

another thought, my buddy just took out his stock sub setup in his sport trac, not sure if he wants to sell it but i could ask him

 

If you don't mind asking him... The part # is XF3F-18C808-AA. There will be a sticker on the side of the amp.

I ordered one of ebay, but the first 4 characters of the part # the actually shipped were different and the plug going to the speaker didn't fit. So, even though the seller advertised it as XF3F-18C808-AA, they didn't have that part and I got stuck with the return shipping just to get my money credited back. I'd prefer to deal with an actual person over ebay @ this point so if he's interested in selling it, I definately want it.

 

That's my next best alternative, I just didn't want to mess with pulling a power wire from the battery and I don't know the ohms rating on the speaker or what frequency I'd need to cross it over at.

If I can find out the x-over frequency and the ohms on the speaker, I'll just buy a cheap amp and wire it up since finding a direct replacement if proving to be harder than I hoped.

 

Thanks, I'll check their website.

 

I found a used one on Ebay. Worked like a champ...

$40 well spent.
