go to jaycar/**** smith and buy 2x IN4004 rectifier didoes, put one on each remote wire connection to each amp with the white band facing the amp.
i.e
head unit remote line ---[ I]---- amp remote terminal
do this on both amps this will only allow the 12v to travel from the head unit to the amp. not sometimes if you have 2 amps sharing a common rem line there can be a little bit of a spike coming back out the line when one of the amps turns off before the other, causing the amp to stay on for a split second too long.
