If I replace the factroy radio with a pioneer AVH-P3200DVD can the volume controls on the steering wheel still be used?

 

you would need an adapter...something like this http://www.crutchfield.com/p_127SWIP...PS.html?tp=476

 

According to crutchfield.com If the factory radio is replaced, the factory sub will no longer work. Is this true because its kind of hard to believe.

 

I know you are two posts in, but a search through the DIY/FAQ section would help you here. There is a way to use the factory sub with aftermarket heads, and it has been reported on and photos have been taken of the exact process.

 

One more question. If I bought the wire harnesses for both the sub and speakers will I be able to control the sub seperately? or would I need to go the route of the rca cables to do that?

 

The wiring harness does NOT work with the sub. In the DIY tutorials I mentioned before, you will see how it connects. Yes you use RCA's off the deck, so control is possible.

 

Well I found this http://beatsonicusa.com/stereo/stere...ic-hsa-09.html this is what I was asking if it will work with the sub

 

That's the expensive way, but sure.

Here's the free way: (and I have to tell you... it was in front of you the entire time you were on this site,...so next time do some searching and you'll be good to go)
