Pretty sure I know the answers but not 100% sure:
1) if I have a 6 channel amp, will I run into problems if 2 of the 6 channels run at different ohms? What about a 5 channel amp where the 5 th channel is at a different impedance? These may be different since as I understand they tend to be two amps built into one.
2) I will have about a month time lapse between installing my h/u and amp. Is it harmful to hook up the RCA cables to the deck and wire them back to where the amp is going to be ahead of time? I don't want to go through taking apart the trim twice.
