i want to know what could be the reason subs cut off and amp fuse keeps blowing? It would really be helpfull if anyone could tell me what to do to solve this problem.

 

Gain cranked? You need to give more specifics.

 

What amp?
What sub(s)?
What load/impedance?
How was gain set?
More info please...

 

also what gauge wire do you have running to your amp vs. how many watts it clames to have. also making sure your power gauge matches your ground gauge, and you have a good ground. what size fuse are you putting on it. we need more info lol
