Power wire grounding
Whether the amp fuse keeps blowing, the ability wire--the wire that goes to the battery or a blazing connection--may be grounding absent. That fuse exists for honest this purpose--to blow before the internals of the amplifier shift ruined. It is specious to fail so that the bounteous expensive components stay intact.
The additional heat from the resistence could cause the amplifier's internal safety to kick on, popping the fuse. Inspect the power wire to the amp, and make sure it is at least Ten gauge in size, no matter what the amplifier's power rating is. The goal is to let the electricity flow as freely as possible. Less work means less heat.
Whether the ground itself is loose and allowed to step in the slightest, it could cause the fuse to blow or the amplifier to close off.
Resistance
Provided the influence wire is as well little in thickness or damaged, it could engender an quantity of resistence, which creates heat, which in turn makes the amp duty harder.
Faulty ground
Provided the ground wire is not fully connected, or the wire is damaged, spikes could antecedent the fuse to fail. Hint the ground wire (nearly always livid for audio amplifiers) to where it is attached to the chassis, inspecting for kinks, tears and other damage. Whether the wire appears in decent shape, peep the connexion objective.Damaged amplifier / wrong fuse size
If the internals of the amplifier are damaged, either through being tossed around in the automobile or being connected wrong, the fuse may blow immediately after power is applied. The only fix for this is To possess a stereo shop repair the amp, or replace the unit completely. The amp fuse would blow to protect the electrical system of the automobile and prevent further damage or fire. Also, using the wrong size fuse in the amplifier can cause it to blow. Check the amplifier fuse opening and the power wire--the correct fuse size is almost always listed.
