[QUOTE="Nickie, post: 8213148, member: 659294"] Hey guys, I am having an issue. I have went through 2 80a fuses in two days. So yesterday I went out and bought a HD-1500 Concept monoblock class D amplifier, a second battery, then proceeded to hook it all up, took my sweet *** time with this btw making sure no wires was going to touch and all that. So last night, new years eve was driving to a local town to watch the "ball drop" listening to it loud for around 30 minutes or so at a time. Well me and my girl watch the ball drop, get back in car head home about 30 minutes later of loud listening. I notice my subs sound like they are losing power, so I pulled over to check it out, My 20 ferad spl cap is reading 9 volts and dropping, so I check the fuse under hood and sure enough, it was melted and blown. So, what is making this fuse do this? My setup JVC headunit 2 batteries 20 ferad spl capacitor 2 rockford fosgate p3's(oldschool silver cones) 4ga wire HD1500 Concept amplifier Wired to 1 ohm, the amp is 1 ohm stable. Now the amp has three 30a fuses, so 90a going to it. Could it be that the amps pulling 90amps through an 80 amp fuse? I figure that might melt the fuse first before blowing it. please someone give me advice, seems everytime I get ahead my systems bitching for more money to be spent on it lol... [/QUOTE]
