i just installed my amp right, and also grouonded the earth under the seat bolts. they are a right ass to get under. anyway,i found the official grounding point, its near the seat bolts,but under the carpet under the back seats. i only found this after i bloody mounted my earth! :x probably a better mounting point,as it must be paint free.
Anyway,how the **** did u all get ur power lead through to the battery? i tried squeezing it through the existing grommet behind the glovebox like some of u have claimed to have done, but i couldnt get mine to fit. :? :x i just cut the grommet in half, making it fit better and whack **** loads of vaseline ontop to seal out the water. gay. :x
