[QUOTE="snoopdan, post: 5626408, member: 564991"] woah homie, you need to get that fuse size down if you want to be competitive. 300 amps would put you in street 4 and you'll be toasted by the veterans. You also need to keep your fusing 18" from your amplifier. Look at doing street 2-3... at least you'll be in the right class. Here is how fusing works : Street 1 0 - 550 pressure class -- 1 Fuse Street 2 551 - 1000 pressure class -- 2 Fuses Street 3 1001 - 2000 pressure class -- 3 Fuses Street 4 2001 - 4000 pressure class -- 4 Fuses Street 5 4001+ pressure class -- Fuses Not Required This is the calculation for pressure classes {(Total Amperage of In-line Fusing X 10) + Woofer Cone Surface Area} = Pressure Class # Examples for 15's (since thats what your running) 30 amps + 1-15's = 477 100 amps + 1-15's = 1177 200 amps + 2-15's = 2353 400 amps + 4-15's = 4707 [/QUOTE]
