the sound is better than stock
connected the negative to the mouting bracket then to car body frame, went out for a drive, tried the horn several times, then stop, got out of the car, closed the door, oh wtf! i got electrified touching the door! it's not like those annoying static shock, this one is quite strong, assume 12V, my thumb hurts a lot, reminds me of some 220V shock before.
well, is this normal, i mean, after disconnect the (negative of) battery and connect again? or should i put a ground wire somewhere under the body and touch the ground or some sort like those old tricks?
i only got electrified once today though, out of 3 or 4 trips.
btw, broke 2 plastic brackets when getting rid of the front facial, and 3 bottom clips seemed not attached. well, the horn sounds better after all.
this one helps
