Ive always used 30amp fuse i have fosgate 250 watt amp the older ones not the new looking style. yes the radio works fine on auxilarary and yes I have the rcas and power cables on different sides. My amp turns on w/ the car not the radio for some reason the remote turn on wire on my deck only puts out 3volts not 12 so its wired 2 turn on w/ the car.\
I had tgis set up wprking for months i sold my subs then i ran into thos problem. i just waab use my ap to wire up 2 speakers in the trunk.
