hi everyone, just fitting the stereo in my mk1 golf gti, just a quick question on the wiring up, i have a battery cut of switch inside the car that runs in betwwen the battery and fuse box to cut everything off when parked, also good anti-thief tool. i have run a new beefy wire from the battery to inside the car to the cut of switch then the fuse box wire connects to the other side, am i ok connecting my amp wire to that power coming into the car or does in need direct connection? it's a 2000w amp and a 3000w dual pioneer Sub.
