If you let us know what kind of car you are installing this in, it would be much easier for us to help you. As far as the remote wire, most factory radios do not have a suitable output wire to turn an amp on. In most cars we would connect the amp remote wire to the switched wire on the radio. Only problem is that the amp will turn on anytime the key is turned on. I would reccomend that you use a line out converter to obtain signal. You really should connect it behind the radio.
