my amp has places for 2 fuses but i guess it only takes one to run it, but anyway it had to 15 fuses in it and it kept blowing one out and not working so i asked stereo place about it and there like oh thats bad amp need to buy another, i was like i think i have to run bigger fuses hes like it doesnt matter there all the same... i put 20 fuse in it just to be safe and it hasnt burnt it up yet...
