Hi all, im looking to upgrade my crappy jbl speakers with some amps and focal speakers. I want to keep my factory head unit so im going to be using the rockford fosgate 3sixty to incorporate the new amps to the head unit. My question is has anyone used the 3sixty? The guy at the local audio store said that I must take the hi level input comming from the h/u after the factory amp. He said if I try to take it right after the h/u my steering wheel controls wont work. I dont think he would have a reason to lie but i've been doing some research on this and many other sites and I never hear of anyone doing this or having a problem like this. Just trying to make sure before I tackle it. Thanks.
