if your going to do that just get a relay and a fuse block, wire it(REM) to a battery fused close to the battery then through the NO contacts on the relay. wire the relay to the h/u acc power to it input and ground everything.. it will **** the relay in once the h/u turns on.. you will never have turn on/ off pops wired like that..
to the guy who says you can get better stuff for the money, you have no clue.. electronics markup plays a huge roll, but no way in hell audiopoop will sound as good put out as much nor be as relabile as the high dollar high end amps like sundown, MMats, RF, AB,SPL dynamics etc... its like saying a saturn will compete with a bmw..
