I can not seem to find a good grounding spot my wire is 4 guage and is only 2 and half feet long and suggestions. I drive a 2000 protege.

So where is the amp installed at? The frame of the car is the best ground around, can you not tap into it? Why can you not change the ground cable? What are we missing here?

power wire with a 40 watt fuse at the battery I have a 1.5 ft ground cable grounded with sanding to the rear-passenger mounting braket nexted to the door, can bridge any of my amps and they are all small except for the shitty jenson amp(it was free) but my kicker and xplode amps both cut out and dont work bridged

well im pretty sure its not a ground problem but more a case of too small of wires how big is that power wire? i dont know what models amps your using but im guessing your doing over 400rms total probably more anyways you should use atleast 8ga wire for three small amps but i would still suggest 4ga also you said you have a 40watt fuse in the power wire is that a 40amp fuse? if not i suggest you use a 25-40amp fuse because a 40 watt fuse would be like useless thats why your amps work when they arent bridged because they arent using much power but when bridged they need nearly double the juice wich they arent getting sorry to ramble so long but i could summ it up any other way lol.
